outer layer of the cerebrum, responsible for conscious behaviour
what are the functional areas of the cerebral cortex?
Motor, Sensory & Association
How is the brain contralateral?
Each hemisphere of the brain handles sensory & motor functions of the
opposite side of the body
How is the brain lateralized?
Although the brain is symmetrical, one side might do more than the other.
Where are the motor areas?
posterior part of the frontal lobe
Where is the primary motor cortex located?
precentral gyrus
What does the primary motor cortex do?
Responsible for the control of skeletal muscles.
,What muscles need the most precise motor control?
The face, fingers and the hands
Where is the premotor cortex located?
anterior to primary motor cortex
What does the premotor cortex do?
Helps plan movements by selecting and sequencing basic motor movements into
more complex tasks (e.g. playing a musical instrument).
What is Broca's area responsible for?
Preparation of speech. -> Organizes the making of sounds that will be heard as
words
What does the frontal eye field do?
controls voluntary eye movements
Where is the primary somatosensory cortex?
postcentral gyrus
What does the primary somatosensory cortex do?
receives sensory inputs from the skin, joints and muscles.
Important for proprioception
,What is the somatosensory association cortex?
-Posterior to the primary somatosensory cortex
-Integrates sensory input and determines size, texture, and relationship of parts of
objects being felt
What is the primary visual cortex
receives and processes incoming visual information
What is the visual association area?
interprets information acquired through the primary visual cortex
Where is the primary visual cortex located?

Evaluates pitch, rhythm and loudness of sound
What does the auditory association area do?
Interprets sounds based on memory.
