TELENCEPHALON DIENCEPHALON
CEREBRAL CORTEX
LIMBIC SYSTEM
BASAL GANGLIA
THALAMUS
HYPOTHALAMUS
 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
 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
 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
 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

 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
