What are the four main regions of the forebrain?
The Frontal, Temporal, Parietal and Occipital Lobes
What are the four main landmarks which divide the forebrain into its four main regions?

What is the Pink area of the forebrain called?
The Occipital Lobe
What is the Green area of the forebrain called?
The Temporal Lobe
Where are the Supramarginal and Angular Gyri?
Sitting on the posterior and inferior side of the parietal lobe (Mc’Donald’s “M”)
Where are the Primary and Secondary Visual Cortices?
In the Occiptal Lobe
Where are the Primary Auditory Cortex and Wernicke’s area?
Along the superior border of the temporal lobe
Where is the Broca’s area located?
Along the Posterior border of the Pre-Motor Cortex, in front of the Pre-Central Gyrus
Where is the Exner’s Area located?
Along the Posterior border of the Pre-Motor Cortex, in front of the Pre-Central Gyrus and above the Broca’s Area
Where is the Postcentral Gyrus/Primary Somatosensory Cortex?
On the posterior side of the Central Sulcus
Where is the Precentral Gyrus/Primary Motor Cortex?
On the anterior side of the Central Sulcus
What Connects the Broca’s and Wernicke’s areas?
The Arcuate Fasiculus
What is the structure Below the Purple region?
The Corpus Callosum
What is the Purple Region?
The Cingulate Gyrus
What is the Sulcus between the Green and Pink Regions?
The Parieto-Occipital Sulcus
What Sulcus runs through the Pink region?
The Calcarine Sulcus
What area of the Occipital Lobe can be identified through looking for the Calcarine Sulcus?
The Primary Visual Cortex
What is the structure below the occipital lobe?
The Cerebellum
What Structuresare part of theForebrain Diencephalon?
The Thalamus, Hypothalamus, and Pituitary Gland
What Structures are part of the Mid Brain?
The Cerebral Peduncles, Cerebral Aqueduct and the Superior and Inferior Collilculi
What Structures are part of the Forebrain?
Cingulate Gyrus, Corpus Callosum, The 4 Lobes,
What Structures are part of the Hindbrain?
Cerebellum, Medulla, Pons Bridge, 4th Ventricle
Where is the Pons?
In the bulge of the brain stem and the area of brainstem behind the bulge
Where is the Medulla?
Below the bulge of the Pons
Where is the Choroid Plexus?
Lining the lateral ventricles
What does the Hypothalamus look like?
A small triangular structure underneath the brain
Where are the Mamillary Bodies located?
Behind the Hypothalamus at its base
Where is the Pituitary Gland located?
Below the Hypothalamus
Where is the Thalamus located?
Above the Hypothalamus
Where are the Superior and Inferior Colliculi located?
Posterior to the 4th Ventricle, Opposite to the Midbrain
Do Primary areas (e.g. Motor, Visual, Auditory) occur in both hemispheres of the brain?
Yes
Do Secondary (Association) areas (e.g. Broca’s, Wernicke’s, SMAGLA) occur in both hemispheres of the brain?
No, only in the dominant hemisphere of the brain (Usually the left)
What structures form the Basal Ganglia?
The Caudate Nucleus, Putamen, Globus Pallidus, Subthalmic Nucleus and Substantia Nigra
What space surrounds the Thalamus?
The 3rd Ventricle
