This document provides an overview of the structure of the human forebrain. It describes the major divisions and regions of the forebrain including the telencephalon, diencephalon, cerebral cortex, limbic system, and basal ganglia. Specific areas that are called out include the primary motor, somatosensory, auditory and visual cortices, as well as the hippocampus, amygdala, thalamus, and hypothalamus. Diagrams are also included showing the lateral and ventral views of the forebrain structure.

CEREBRAL CORTEX
LIMBIC SYSTEM
BASAL GANGLIA
THALAMUS
HYPOTHALAMUS

3.  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

4.  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

5.  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

6.  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

10. CORPUS CALLOSUM-
egion connecting the
two cerebral
hemispheres
CINGULATE GYRUS-
Just above the corpus
callosum

13.  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
