Neuroscience Fundamentals for Communication Sciences and Disorders

Neuroscience Fundamentals for Communication Sciences and Disorders, Second Edition is a comprehensive textbook primarily designed for undergraduate neural bases or graduate neuroscience courses in communication sciences and disorders programs (CSD). The text can also be used as an accessible go-to reference for speech-language pathology and audiology clinical professionals practicing in medical and rehab settings. Written with an engaging and conversational style, the author uses humor and analogies to explain concepts that are often challenging for students. Complemented by more than 400 visually rich and beautifully drawn full-color illustrations, the book emphasizes brain and behavior relationships while also ensuring coverage of essential neuroanatomy and neurophysiology in an integrative fashion. With a comprehensive background in the principles, processes, and structures underlying the workings of the human nervous system, students and practitioners alike will be able to better understand and apply brain-behavior relationships to make appropriate clinical assessments and treatment decisions.

Extending well beyond traditional neuroanatomy-based textbooks, this resource is designed to satisfy three major goals:

• Provide neuroanatomical and neurophysiological detail that meets the real-world needs of the contemporary CSD student as they move forward toward clinical practice and into the future where advancements in the field of health and brain sciences are accelerating and contributing more and more each day to all areas of rehabilitation.
• Provide clear, understandable explanations and intuitive material that explains how and why neuroanatomical systems, processes, and mechanisms of the nervous system operate as they do during human behavior.
• Provide a depth and scope of material that will allow the reader to better understand and appreciate a wide range of evidence-based literature related to behavior, cognition, emotion, language, and sensory perception—areas that all directly impact treatment decisions.

New to the Second Edition

• 40 new full-color illustrations 
•  Reorganization and division of content from Chapters 4, 5, and 6 of the previous edition, into six new and more digestible chapters
•  A new standalone chapter on the cranial nerves 
•  Addition of a major section and discussion on the neural bases of swallowing
•  Addition of more summary tables and process flowcharts to simplify the text and provide ready-made study materials for students 
•  Revisions to most figures to improve their clarity and coherence with the written material

Praise for the First Edition

"This text is excellent. I love the analogies and descriptive illustrations to aid comprehension. I really appreciate having the option for unlabeled images. I put those on my class handouts to work on as we are learning new material. Best text I have ever used."
— Kelly Kleinhans, PhD, Associate Professor and Program Director, Master of Speech-Language Pathology, Austin Peay State University

"It is more in-depth than most, if not all, the books I have considered for teaching undergraduate neuroscience for Communication Sciences and Disorders majors. This book tackles a very difficult and dense subject using a mixture of strong, clear explanations and humor that will help students during their introduction to neuroscience. Neuroscience is often one of, if not the most daunting topics for our undergraduates, and this book makes it very digestible."
—Daniel Furnas, PhD, Assistant Professor, Communication Sciences and Disorders, Jacksonville University

"Andreatta has taken a different approach that is considerably less intimidating than other texts. The use of mild humor, analogies and the manner in which concepts are presented makes this an easy yet comprehensive read. It is probably the most comprehensive and student friendly text that I have seen written for undergraduate students."
—Carol Deakin, PhD, Associate Professor, Communication Sciences and Disorders, Alabama A&M University

"Humor throughout the text adds to the readability. Neuroscience can make for dry reading, but the humor makes it lighter. The manuscript is very thorough and covers a substantial number of topics. The chapter on the ear is excellent. ...It is much better than a comparable neuroscience for CSD text that I have used in the past."
—Jeremy J. Donai, AuD, PhD, Assistant Professor, Department of Communication Sciences and Disorders, West Virginia University

"The primary strength of this text is in its detail and organization. A very complete, well-written text. Its scope includes explanations of the mechanisms of the brain underlying basic and skilled actions from cellular functions, anatomic structures and physiologic processes of the nervous system. With a solid background in neuroscience, students will be able to better understand brain-behavior relationships in order to make appropriate clinical assessment and treatment decisions. The relatable examples, with a touch of humor, makes the text very readable. Students should be able to relate to all analogies and this prevents the reader from getting too bogged down in detail as they attempt to understand complex concepts."
—Janis M. Jarecki-Liu, PhD, Professor, Department of Communication Sciences and Disorders, Clarion University of Pennsylvania

"The author is very creative and the relatable, conversational style of this book is a definite strength. The author uses well placed, vivid analogies to explain concepts that can be quite challenging for students. The overall structure and organization of the book is also a strength as it uses a logical progression of the material."
—Irene M. Barrow, PhD, Professor, Department of Communication Sciences and Disorders, James Madison University

"As a student, I was intimidated by the complexity and grandeur of the nervous system. Dr. Andreatta's textbook, however, explained neuroscience in such an approachable and engaging manner. This textbook was truly a bright spot of a difficult semester, lighting a passion for neuroscience within me with fascinatingly clear food analogies and pockets of humor and empathetic notes throughout." 
—Peace Lu, Struggling Student Who Ended Up Fascinated With Neuroscience 

Review

“…The book targets several different audiences: senior undergraduate and graduate students in speech-language pathology, students in doctoral audiology programs, practicing clinicians, and faculty in Communication Sciences and Disorders (CSD), including those without neuroscience expertise. It is also accessible to those without any formal training in neuroscience. The book is organized, well-written, and illustrated in a way that faculty can use when teaching the neural bases of speech and language. The book serves as a useful guide to help lecturers build a course, create course content and/or materials, and design and develop lectures.
The book is divided into four sections, each with a list of corresponding chapters. This handy feature aids in conveying the four overarching topics of the book, and supports clinicians who wish to reference the book with a specific inquiry. To assist in learning and solidifying information, each chapter contains a "Top Ten" section that provides a thorough overview of the chapter's main points. The chapter covering the neural underpinnings necessary for speech includes several different modalities for effective learning: easy-to-read charts, engaging and amusing language, visual figures, and real-life situational examples of neurological involvement. This second edition book provides more full-color illustrations than the first edition, and includes more summary tables, flow charts, and revised visual figures…
This book is a worthy resource for any student or clinician requiring knowledge of neuroanatomy and neurophysiology. It covers the subject area in a comprehensive manner, allowing both students to acquire necessary groundwork knowledge and clinicians to reference the information in practice.”
– Melissa Raymond, M.S, Biola University, from Doody’s Reviews (May 2023)
