PRIMARY MOTOR CORTEX

–region of the posterior frontal

lobe involved in movement.

PRIMARY

SOMATOSENSORY

CORTEX-located caudal to the

central sulcus.Receives

information from the body

senses

PRIMARY AUDITORY

CORTEX-Located on the upper

surface of the lateral fissure

which receives auditory

information.

PRIMARY VISUAL

CORTEX-Located at the back

of the brain.Receives visual

information

The outer layer of the cerebral

hemispheres

Page 4: Fore brain

HIPPOCAMPUS-Forebrain

structure of the temporal lobe

AMYGDALA-Interior of the

rostral temporal lobe

FORNIX-is a bundle of axons

that connects the

hippocampus with other

regions of the brain

Page 5: Fore brain

Basal ganglia is located

beneath the anterior portion

of the lateral ventricles

Caudate nucleus is a tail like

nucleus that extends in each

hemisphere from the

amygdala

Putamen is located in each

hemisphere just lateral to the

globus pallidus

Globus Pallidus is located

between the thalamus &

putamen

Page 6: Fore brain

IT’S THE SECOND MAJOR

DIVISION OF THE

FOREBRAIN

Thalamus-situated near the

middle of the cerebral

hemisphere,makes up the

dorsal part of diencephalon

Hypothalamus-lies at the base of

the brain under the thalamus

CORPUS CALLOSUM-

egion connecting the

two cerebral

hemispheres

CINGULATE GYRUS-

Just above the corpus

STRUCTURE FRONTAL LOBE -includes

everything in front of central

sulcus

PARIETAL LOBE-located on

the side of the cerebral

hemisphere just behind the

central sulcus

TEMPORAL LOBE-juts

forward from the base of the

brain

OCCIPITAL LOBE-lies at the

very back of the brain.caudal to

the parietal and temporal lobes
