2-Minute Neuroscience: Ventral Tegmental Area

October 5, 2016


In this video, I discuss the ventral tegmental area, or VTA. The VTA is one of the two largest dopaminergic regions of the brain (the other being the substantia nigra). Dopamine neurons leave the VTA in several different pathways and project throughout the brain. The mesocortical pathway projects from the VTA to widespread areas of the cerebral cortex and has diverse functions including motivation, emotion, and executive functions. The mesolimbic pathway projects from the VTA to several limbic structures; the largest projection is to the nucleus accumbens. The mesolimbic pathway also has diverse functions but is best known for its role in processing rewarding stimuli.

YOUR BRAIN, EXPLAINED

Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Building on neuroscientist Marc Dingman’s popular YouTube series, 2-Minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks using real-life examples and Dingman’s own, hand-drawn illustrations.

  • Dingman weaves classic studies with modern research into easily digestible sections, to provide an excellent primer on the rapidly advancing field of neuroscience. - Moheb Costandi, author, Neuroplasticity and 50 Human Brain Ideas You Really Need to Know

  • ...a highly readable and accessible introduction to the operation of the brain and current issues in neuroscience... a wonderful introduction to the field. - Frank Amthor, PhD, Professor of Psychology, The University of Alabama at Birmingham, author, Neuroscience for Dummies

  • An informative, accessible and engaging book for anyone who has even the slightest interest in how the brain works, but doesn’t know where to begin. - Dean Burnett, PhD, author, Happy Brain and Idiot Brain

  • Reading like a collection of detective stories, Your Brain, Explained combines classic cases in the history of neurology with findings stemming from the latest techniques used to probe the brain’s secrets. - Stanley Finger, PhD, Professor Emeritus of Psychological & Brain Sciences, Washington University (St. Louis), author, Origins of Neuroscience
