Hemispheric Lateralisation And Split Brain Research

Question 1

What is hemispheric lateralisation

Answer 1

The idea that two halves of the brain are almost independent of each other and they are functionally different. Left side is dominant for language, right side is dominant for visual motor tasks

Question 2

The corpus callosum is what

Answer 2

Bundle of neurons that connect the hemispheres and allow both sides to talk to each other

Question 3

What is contralateral control

Answer 3

The right hemisphere of the brain controls the left side of the body and the left hemisphere controls the right side of the body

Question 4

What are split brain patients

Answer 4

The connection between the two hemispheres is cut during surgery, this means that they can’t communicate with each other. This procedure was used for a treatment for severe epilepsy

Question 5

Who were the first to investigate hemispheric lateralisation

Answer 5

Sperry and Gazzaniga, their aim was to examine the extent to which two hemispheres are specialised for certain functions

Question 6

What was the findings of spilt brain research

Answer 6

Facial recognition is in the right hemisphere
Speech and language in the left side

Question 7

Problems with sperrys work is what

Answer 7

Lack temporal validity and population validity as the research takes an idiographic approach

Question 8

Who is Kim peek

Answer 8

He was born without a corpus callosum so he was a natural born split brain patient.
He contradicts split brain research and he could read both pages of an open book at once
