PSYCH JULY MOCKS BIOPSYCH LONG ANSWER OUTLINE

define localisation

the designation of a function to a specific area in the brain

motor cortex location function damage

LR frontal lobe voluntary movement loss of fine motor skills

somatosensory centres location function damage

LR parietal lobe sensory information loss of sensation

visual centre location function damage

LR occipital lobe visual processes blindness

auditory centres location function damage

LR temporal lobe analysis of speech info hearing impairments

brocas area location function damage

L frontal lobe speech production and fluency brocas aphasia

what is brocas aphasia

slow laborious speech

wernickes area location function damage

L temporal lobe understanding language and accessing words wernickes aphasia

what is wernickes aphasia

fluent speech lacking meaning

define hemispheric lateralisation

the tendency of brain functions to be specialised to a hemisphere of the brain

what is the communication pathway between the right and left hemisphere called

corpus callosum

what does contralateral mean

opposite sides dealing with opposite sides of the body

what is the function of the left brain

analysis language english and maths

what is the function of the right brain

synthesis spacial info music art and emotion

what is plasticity

the brains tendency to change as a result of new experiences

when does our brain grow the most synaptic connections and how much

infancy peaking at 3 with 15000 connections

what is synaptic pruning

the deleting of unused synaptic connections and the strengthening of commonly used ones

what is functional recovery

the redistribution or transferring of functions following brain damage

what is neural regeneration

the growth of new neural connections to compensate for damaged areas

what is spontaneous recovery

the rapid process of transfer of function to healthy brain areas

what happens when functional recovery slows

rehabilitation

give examples of trauma

physical trauma and bacterial infections

give examples of effects of trauma

amnesia and aphasia

what is axon sprouting

axon damage leading to other axons connected to the same neuron sprouting more connections

what is neuronal unmasking

the awakening of dormant synapses to increase neural input to damaged areas

what factors can make recovery slower

age gender and alcohol consumption

what is split brain research

the severing of the corpus callosum(commissurotomy) to study the link between the hemispheres of the brain

who is the named psychologist for split brain research

sperry

outline sperrys split brain research study

if an image was flashed in the right visual field they could say what they saw if in image was flashed in the left visual field they couldn’t say what they saw but could select the object with their left hand

explain the results of sperrys study

the severing of the CC meant communication between the hemispheres could not occur and info going to the right hemisphere could not be converted into language
