split brain research / Brain techniques

Question 1

hemispheric lateralisation

Answer 1

the idea that the two hemispheres of the brain are functionally different and that certain mental processes and behaviours are mainly controlled by one hemisphere rather than the other

Question 2

split brain research

Answer 2

a series of studies which began in the 1960’s involving epileptic patients who had undergone a surgical separation of the hemispheres of the brain. allowing researchers to investigative the extent in which brain function is lateralised

Question 3

brain technique 1 = functional magnetic resonance imaging (fMRI)

Answer 3

a method used to measure brain activity while a person is performing a tasks that uses MRI technology. enabling researchers to detect which regions of the Brian are rich in oxygen and thus are active.

Question 4

brain technique 2 = Electroencephalogram (EEG)

Answer 4

a record of the tiny electrical impulses produced by the brain activity. bu measuring charcaterstics wave patterns, can help diagnose certain conditions of the brain

Question 5

brain technique 3 = Event related potentials ( ERPs )

Answer 5

the brains electrophysiological response to specific sensory, cognitive or motor events can be isolated through statistical analysis of EEG

Question 6

brain technique 4 = post mortem examinations

Answer 6

the brain is analysed after death to determine whether certain observed behaviours during the patients lifetime can be linked to abnormalities in the brain
