in lateral
ventricles goes
into the third
ventricle.

Foramen of Monroe or the interventricular foramen
Third ventricle is bounded on either side by the hypothalamus.
Thalamus is above the third ventricle.
8. Cerebrospinal fluid
• Cerebrospinal fluid exits the brain ventricles and flows around the
entire cerebral hemisphere in subarachnoid space.
• The subarachnoid space contains one or two millimeters of CSF.
• CSF is an important pyhsical buffer.
• The drainage of CSF along the dorsal midline is happening via
subarachnoid granulations.
• Subarachnoid granulations are one-way valves that allow CSF to leave
the subarachnoid space and drain into the superior sagittal sinus.
• From the superior sagittal sinus (and other sinuses) CSF goes back to
the venous blood.
15. The internal capsule
• The internal capsule is the massive system of white matter that runs
between the cerebral cortex and everything that falls below the cerebral
cortex.
• Internal capsule axons pass the thalamus, brain stem and spinal cord:
many of axons are going in descending direction.
• Axons that are coming from the thalamus are projecting back to the
cerebral cortex.
Axons of the internal capsule are slipping between:
• the body of caudate nucleus, the thalamus
• the putamen, the nucleus accumbens
AND
18. Function
Putamen regulates movement of the body.
Caudate nucleus regulates movements of the
eyes, movements of the mind and thoughts.
Nucleus Accumbens is involved with
modulating movements of emotion or mood.
