As professional counselors learn more about neuroscience, they need guidance on how to integrate this new knowledge into counselor education and counseling practice with clients. The purpose of this updated edition is to provide a comprehensive resource for translating and applying neuroscientific concepts to the theory and practice of counseling.
The authors provide guidance as to how counselors integrate neuroscience into their work, with the hope of better understanding and identifying methods for effectively and responsibly incorporating key principles of neuroscience into the profession. This new edition incorporates the 2024 CACREP Standards as markers of learning, to ensure that CACREP-accredited programs have the information needed to apply neuroscientific concepts to all the major areas of counseling practice.
This volume addresses the 2024 entry-level educational standards of the main accrediting body of the counseling profession, CACREP. Each of the eight common core areas of counseling knowledge and skills are covered (professional counseling orientation, social and cultural foundations, human growth and development, career development, helping relationships, group counseling and group work, testing and assessment, research and program evaluation). Several 2024 CACREP Standards that are integrated into the eight common core standards, such as the impact of crises, disaster, and traumatic events; the neurobiology of addictions; wellness and optimal performance; and psychopharmacology are also addressed. Some chapters also focus on doctoral-level 2024 CACREP standards for counselor education and supervision.

We dedicate this book to everyone who has been working toward integrating neuroscience into the counseling field and to the next generation of counselors, eager to understand the connections between brain, mind, body, and behavior.
Thomas A. Field, Laura K. Jones, and Lori A. Russell-Chapin have individually written some of the most inspiring and practical textbooks that integrated neuroscience and neuroscientific concepts into the counseling field. Here in the second edition of their edited book, Neuroscience-Informed Counseling: Brain-Based Clinical Approaches, they contribute to the continued significance of enhancing the relational work that counseling professionals and counseling students do by being informed by neuroscience research and literature. This book not only speaks to the dialogues between brain, mind, body, and behavior in a deficit-focused way but also helps counseling professionals conceptualize biological, neurological, and physical factors that play a role in from human development over the life span to overall wellness. Additionally, the organization of the book’s chapters aligns with the step-by-step approach addressed in a training model established for development of neuroscience competencies in counseling professionals.
— Yoon Suh Moh, PhD, LPC, CRC, NCC, BC-TMH, BCN, author of Neurobiology of Stress-Informed Counseling: Healing and Prevention Practices for the Helping Professions
The latest edition of Neuroscience-Informed Counseling successfully bridges the gap between neuroscience research and practical clinical application. Packed with insightful case illustrations, this invaluable book translates emerging brain science into clear interventions clinicians can employ immediately for improved treatment outcomes. I am thrilled to recommend the newest edition of this essential guide to brain-based therapies. The authors have vastly expanded the clinical utility for frontline counselors through enhanced psychopharmacology content, lifespan neurodevelopmental context, and demonstrating neuroscience-aligned skills via rich case scenarios. Connecting neurophysiological processes with counseling best practices, this multidimensional resource truly empowers therapist capabilities. From illuminating how neurobiology interacts with substance abuse to providing neuroscience interventions across specialty areas, practitioners now have an accessible framework for harnessing this knowledge toward evidence-based care.
— Carl Sheperis, PhD, NCC, CCMHC, MAC
An excellent and accessible read to get therapists up to speed on the brain. Practicing counselors have limited time to stay on top of current research, and we all know how mentally draining it can be trying to piece together real world applications from abstract publications. This updated edition of Neuroscience-Informed Counseling: Brain-Based Clinical Approaches does the heavy lifting for you, summarizing thousands of hours of reading into key observations and practical suggestions specifically relevant to the modern clinician. As a licensed therapist who has spent 20 years designing clinical applications for neurotechnology, I have seen many deeply curious counselors who want answers but don't know where to begin. This book is the solution: the perfect starting place for busy, overwhelmed clinicians to learn how to counsel mind, body, and brain.

This first section of the text reviews foundational knowledge needed to conceptualize client cases from a neurophysiological perspective. You will first be introduced to basic brain anatomy and systems before learning about neurophysiological development across the life cycle and the impact of neurophysiological marginality and traumatic stress on psychological health. This knowledge is considered fundamental to understanding the client’s presenting problem from a neurophysiological perspective, leading to more effective counseling relationships, assessments, and interventions.
Laura K. Jones
Learning about brain anatomy and the functioning of related systems may not be the first thing that comes to mind when you think about counselor education and training. You may wonder how your clinical decisions with a client, supervisor, or community would be influenced by your knowledge of the brain and body. As you read this and later chapters, you might find yourself becoming fascinated by the many wonders of the brain and body and how this information affects your work as a counselor.
Interest in the application of neuroanatomy to mental health has been long-standing. Sigmund Freud (1914/2014) suggested in his classic paper On Narcissism that “we must recollect that all of our provisional ideas in psychology will presumably one day be based on an organic substructure” (p. 78). Since Freud’s early conjecture, limitations in technology have hampered understanding of the effect of the workings of the brain on mental health functioning. On April 2, 2013, a paradigm shift in mental health research began with the launch of the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative. The mission of this initiative is to understand “the circuits and patterns of neural activity that give rise to mental experience and behavior” (National Institutes of Health, 2014, p. 12) and, in doing so, to cultivate an integrative understanding of brain-behavior processes. As technology and science continue to develop, so may our understanding of mental health as being a result of an intricate interplay between the brain, immune, endocrine, and gastrointestinal systems (Anisman et al., 2018; Brown et al., 2020; Hou et al., 2022; Peirce & Alviña, 2019; Skonieczna-Żydecka et al., 2018). This chapter is a first step in introducing you to the inner workings of the brain in an effort to inform your case conceptualizations, treatment plans, and clinical effectiveness with clients.
This chapter addresses 2024 Council for Accreditation of Counseling and Related Educational Programs (CACREP) Standards pertinent to the Foundational Counseling Curriculum (Section 3) area of Lifespan Development (Standard C):
Theories of learning (Standard C.3.)
Biological, neurological, and physiological factors that affect lifespan development, functioning, behavior, resilience, and overall wellness (Standard C.10.)
Rein is a 12-year-old female preadolescent of Native American descent. Her home environment is intact; she lives with both parents and a brother. Rein describes having an attentive but reserved family with limited communication regarding emotions, physiological changes to the body, or interpersonal relationships. Her parents scheduled an appointment because of a marked decrease in Rein’s grades at school—Rein previously having been a straight A student—and a noticeable withdrawal from group activities during class. Rein reports feeling very sad and lonely and indicates that she has been feeling increasingly more distant from friends in the past 6 months. Rein denies feeling bullied or victimized, but she does not feel that anyone likes or understands her and has a hard time connecting with others. She also reports feeling lethargic. Her mother confirms that Rein often cries and isolates herself from her family. Her mother also shared that Rein recently reached menarche and was concerned that Rein may feel embarrassed about this.
Despite incredible advances in science, the human brain in many ways remains a mystery. Part of its enigmatic nature rests in its complexity. Not only are various internal and external structures of the brain specified for certain functions, but those parts directly and indirectly influence one another and other parts of the body by way of various chemical messengers and electrochemical networks. Furthermore, several areas of the brain can work in concert to govern other aspects of an individual’s mental and physical functioning. Something as simple as reading the word “counselor” requires a remarkable succession of processes that involve virtually the entire brain.
In addition, researchers are now discovering more about how a person’s physical health, and even the nature of the microbes in their gut, influences the functioning of the brain and vice versa. Some of the paradigms of mental health are now shifting as researchers begin to further investigate the reciprocal functioning of the body and brain, such as the role of inflammation (the process by which white blood cells help to protect people from infection) in depression (Miller & Raison, 2016). Thus, let us explore some of what is known about the various parts and coordinated systems of the brain and body.
What is your first thought when you hear the word “brain”? Most people think of a gray folded mass that sits inside the skull. This folded mass is the outer layer or lateral part of the brain, called the cerebral cortex, or cortex for short. You may also know that in the interior of this folded cortex are other exceedingly important parts of the brain. These internal and external structures control virtually everything about you. They allow you to think, feel, behave, breathe, and survive.
The cerebral cortex, or outermost part of the brain, is actually a 2- to 4.5-millimeter-thick mass of gelatinous tissue (Fischl & Dale, 2000). Even though it is often thought of as gray (and parts of it are called gray matter), it is actually pink when it is healthy living tissue, much like other tissue in the body. This folded mass includes the ridges of cortex known as gyri (singular, gyrus) and the shallower grooves between the gyri known as sulci (singular, sulcus). Fissures are similar to sulci but are deeper and more clearly divide regions of the brain. The gyri, sulci, and fissures help to demarcate different regions of the brain.
The cortex is made up of two hemispheres: one on the left and one on the right. Connecting these two hemispheres is a thick band of nerve fibers known as the corpus callosum. It is the largest collection of nerve fibers in the entire nervous system, containing roughly 200 million interhemispheric connections (Luders et al., 2010). This band of fibers allows the two hemispheres to communicate back and forth and integrate the information being processed on either side of the brain. A common misconception in popular culture is that individuals are either “left brained” or “right brained.” It is accurate that certain functions may be predominantly controlled by brain regions in one hemisphere or another; for example, the area of the brain responsible for language production is typically located in the left hemisphere. Yet the notion that a person can be either left brained or right brained is an overgeneralization and a misrepresentation of brain functioning. More often than not, both sides of the brain are working in coordinated action to allow people to more fully perceive, respond, and adapt to their internal and external environments.
The cerebral cortex is further divided into four sets of primary lobes, with analogous lobes in each hemisphere. Each lobe is specialized for certain functions, such as sight, somesthesis (e.g., skin senses and proprioception), hearing and language comprehension, motor control, and executive functioning. The four lobes are the occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Figure 1.1 depicts the general location of each of the four lobes.

Occipital lobe. At the very back of the brain sits the occipital lobe, which is the smallest of the four lobes. This is the visual center of the brain. The occipital lobe pieces together the visual components of the surrounding world. This allows people to interpret and understand what their eyes are seeing, such as shape, color, size, depth, and motion. However, visual processing is limited, meaning that people cannot process everything in the world around them. Visual perception is determined by several factors, including how many objects are present, how long the objects are in the visual field, and to which objects people allocate their attention.
Parietal lobe. The parietal lobe is located between the frontal lobe and the occipital lobe toward the crown of the head. This part of the brain contains the primary somatosensory cortex, which regulates the sensations that are perceived by the physical body, such as touch (e.g., temperature, pressure, pain), and the awareness of bodily movement and the orientation of the body in space (i.e., proprioception). The most anterior (i.e., toward the front) gyrus of this cortex (i.e., the postcentral gyrus) extends across both hemispheres and contains a map of one’s entire body. For example, regions of this gyrus represent the thumb, tongue, arm, stomach, and even pinky toe. Every part of the body that one can feel is allocated a certain area of cortex on this gyrus, with the number of sensory receptors on the skin of that area governing how much of the cortex it represents. For example, the hands, face, and tongue are all represented by very large areas of cortex because people need to have very refined sensations of touch for these areas. The body maps are also contralateral (as opposed to ipsilateral), meaning that the right side of the body is mapped onto the left postcentral gyrus and vice versa.
Temporal lobe. The temporal lobe is located just behind the ears, below the parietal lobe and between the frontal lobe and the occipital lobe. The primary function of the temporal lobe is hearing and language comprehension. This region of the brain allows people to put together and comprehend the various sounds that are coming into their ears. Wernicke’s area is the region of the temporal lobe that allows people to process spoken language. The temporal lobes are also involved in memory. The hippocampus is located in the medial (i.e., interior) region of the temporal lobes and is responsible for the formation of long-term, explicit (i.e., consciously declared or declarative) memories.
Frontal lobe. The front section of the brain contains the largest cortical lobe—and the largest of any mammal—which covers nearly half of the entire cortex. Aptly named the frontal lobe, this area is also the most extensive in terms of the functions that it controls. The most posterior (i.e., toward the back) gyrus of the frontal cortex (neighboring the parietal lobe) contains the primary motor cortex. Like the postcentral gyrus (i.e., somatosensory cortex), this area contralaterally maps out the entire body, not for the purpose of feeling those parts but for the purpose of moving them. So as you reach to turn the page of this book, neurons (i.e., brain cells) in the upper left side of this gyrus (or the right side if you are using your left hand) are firing.
At the base of this primary motor cortex, extending down and forward and typically in the left hemisphere, is Broca’s area, which is responsible for language production. Note that the area for language comprehension is different from that for language production. Broca’s area is located at the base of the primary motor cortex because that
