Introducing Mind and Brain - Angus Gellatly & Oscar Zarate


A fun comic style attempt at understanding the workings of the human brain.

The approach here is to identify disorders and map them to the physiology of the brain. A reasonably good approach since this how we have come to understand a lot about how the brain works (although feel a bit for people who experience such disorders).

Here are some disorders that I had no prior knowledge of ...

achromatopsia : loss of color vision caused by damage to V4 region in the brain
broca's apasia : disorders of speech
ideomotor apraxia : difficulty making movements and gestures
scotoma : blind spot caused by damage to V1
object agnosia : inability to recognize objects
form agnosia : can see color, depth and contour but percieves only parts, not whole objects
simultagnosia : objects are percieved and recognized, but only one at a time
associative agnosia : a patient can describe or draw visual scenes and objects, but there is a failure of recognition
prospagnosia : problem in recognizing familiar faces
jamais vu : recognition without familiarity
balint's syndrome : can recognize objects accurately, but cannot accurately reach for them
