What is the occipital lobe mainly involved in?
|
Selecting, organsing and interpreting vision

|
|
What is an ESB and why are they performed?
|
Parts of the brain are withere chemically or electrically stimulated which make it possible to see what part of the brain is responsible for functions
|
|
|
What is hemispheric specialisation?
|
The dominance of certain functions by each of the cerbral hemispheres of the brain

verbal functions, logical functions such as maths and language
|
|
|
What happens when Wernicke's area is damaged?
|
People are still able to speak fluently however their words become like a word salad.

|
|
What do sensory areas in the brain do?
|
RECIEVE and PROCESS information from sensory receptors

What are the three cortical areas?
|
Sensory, motor and asscoiation
|
|
|
How much of the brains nuerons are located in the cerebral cortex?
|
Three quarters
|
|
|
What is the role of the parasympathetic nervous system?
|
calms the body and returns it to an equilibrium after the effects of the sympathetic nervous system are no longer needed
|
|
|
What do association areas in the brain do?
|
INTERGRATE motor and sensory information. Involved in things such as thinking and percieving
|
|
|
What is an EEG?
|
DARE:
detects, amplifies and records electrical activity of the brain. Used to identify regions of the brain that are most active during different functions |

|
|
What do motor areas in the brain do?
|
RECIEVE, PROCESS and SEND information about voluntary body movements
|
|
|
What is a PET scan?
|
Radioactive substances are injected into the brain and track glucose through the brain showing the amount of activity in different parts of the brain
|
|
|
What is respect for persons?
|
proper regard by the researcher for the welfare, rights, beliefs and customs of all individuals involved in research

|
|
What are the brain research methods that measure function?
