Motor Cortex

Responsible-->generating voluntary movements
Found--> frontal lobe

Motor Cortex-->both hemispheres-->control opp sides of body.

1 of 9

Somatosensory Cortex

detects sensory events from parts of the body

sensory info-->skin-->SC produces touch,

pressure, pain, temperature.

both hemispheres-->SC-->info opp sides of body.

2 of 9

Visual centres

visual centre located-->visual cortex

nerve impulses-->retina-->optic nerve-->part of

brain controlling circ rhythm

Both hemispheres--> input from opp sides

3 of 9

Auditory Centres

Located-->temporal lobe

Most of area is on both sides of brain

sound waves-->nerve impulses-->auditory nerve-->auditory cortex

4 of 9

Broca's area

Paul Broca-->Tan-->only syllable-->patient say

Tan-->understand language-->cannot speak + write thoughts

Patients-->damage-->left frontal hemisphere-->lang issues

Patients-->damage-->right frontal hemisphere
-->none

Existence-->language centre-->

5 of 9

Wernicke's area

Left temporal lobe

Patients-->speak-->unable-->understand language

Proposed-->language involves separate motor and sensory regions

Evaluation: Challenges to localisation

Not all researchers agree that cog functions happen in the brain.

Intact areas of the cortex could take over responsibility of injured areas responsible for that function.

Effect of the damage is therefore determined by extent rather than location

7 of 9

Evaluation: Communication may be more important that localisation

How areas communicate may be more important than which area controls what

Wernicke claimed that although areas are specialised in order to work they must communicate first.

suggests complex behaviours are built up gradually and moved through different s

8 of 9

Evaluation: individual differences in language areas

pattern of activation observed in response to language can vary

studies have found differences in brain area size associated with language

anatomical differences may explain superior language skills found in females.
