Connection between 2 hemispheres?

Corpus Callosum = thick bundle of nerve fibres allowing quick communication between both sides.

1 of 7

Contralateral?

each hemisphere controls op. sides of body.

2 of 7

right side of brain deals with (and vice versa but language centres as well)?

visual information in left visual field taken from optic nerves of both eyes

3 of 7

Sperry- 1968

-research study on 11 patients who had corpus callosum cut to treat epilepsy.
-also key, saw words in visual fields. key- left= can say key but saw-right- can't speak but can draw a saw with left hand.
- suggests hemispheres are both capable of acting in

Gazzangina- 1983- facial recognition

variation of Sperry's research
faces shown to right hemisphere we're recognised.
shows RH= better at recognising faces

Split brains?

cutting corpus callosum. reduces epileptic symptoms and few side effects but unusual behaviour and sense of loss of agency led to research.

6 of 7

Evaluation of Sperry's research.

- small sample size and had varying amounts of connection cut and all undergone drug therapy. suggests some results may be due to participant variables making results ungeneralisable to wider population.
-the experimental procedure is unlike how individua
