PSYC 305L Lecture Notes - Lecture 40: Transcranial Magnetic Stimulation, Occipital Lobe, Brain Damage
Document Summary
Visual imagery and the brain, there is a clear biological evidence between imaging and perceiving a. i. A great deal about the specific brain structures are required for vision a. i. 1. a. i. 2. Many of the same structures are crucial for imagery. Vision relies heavily on tissue located in the occipital cortex: visual imagery and brain disruption b. i. A technique that creates a series of strong magnetic pulses at a specific location on the scalp b. i. 1. a. Temporarily disrupts the brain region directly underneath the scalp area b. ii. Brain damage also causes parallels in how people pay attention to visual inputs and to visual images: spatial images and visual images c. i. c. ii. c. iii. Blind individuals produce responses times proportional to the distance traveled in the image just as with participants who have normal vision. Spatial imagery might be represented in the mind in terms of a series of imagined movements, so that it is body imagery or motion imagery rather than visual images.
