Arcuate fasciculus - definition

a neuronal pathway traditionally thought to connect Broca’s and Wernicke’s areas and to play an important role in transferring information about language between them. More recent research has suggested that the anatomy and function of the arcuate fasciculus is more complex than initially thought.

IN THIS IMAGE, BROCA’S AREA IS REPRESENTED BY THE BLUE REGION CLOSER TO THE FRONT OF THE BRAIN (ON THE LEFT), WHILE WERNICKE’S AREA IS REPRESENTED BY THE BLUE REGION CLOSER TO THE BACK OF THE BRAIN (ON THE RIGHT). THE RED LINES REPRESENT THE ARCUATE FASCICULUS, CONNECTING THE TWO REGIONS. — In this image, Broca’s area is represented by the blue region closer to the front of the brain (on the left), while Wernicke’s area is represented by the blue region closer to the back of the brain (on the right). The red lines represent the arcuate fasciculus, connecting the two regions.

BIZARRE

This book shows a whole other side of how brains work by examining the most unusual behavior to emerge from the human brain. In it, you'll meet a woman who is afraid to take a shower because she fears her body will slip down the drain, a man who is convinced he is a cat, a woman who compulsively snacks on cigarette ashes, and many other unusual cases. As uncommon as they are, each of these cases has something important to teach us about everyday brain function.

Dingman brings the history of neuroscience back to life and weaves in contemporary ideas seamlessly. Readers will come along for the ride of a really interesting read and accidentally learn some neuroscience along the way. - Erin Kirschmann, PhD, Associate Professor of Psychology & Counseling, Immaculata University
Bizarre is a collection of stories of how the brain can create zombies, cult members, extra limbs, instant musicians, and overnight accents, to name a few of the mind-scratching cases. After reading this book, you will walk away with a greater appreciation for this bizarre organ. If you are a fan of Oliver Sacks' books, you're certain to be a fan of Dingman's Bizarre. - Allison M. Wilck, PhD, Researcher and Assistant Professor of Psychology, Eastern Mennonite University
A unique combination of storytelling and scientific explanation that appeals to the brain novice, the trained neuroscientist, and everyone in between.
