• Internal capsule

Basal Ganglia

• Caudate nucleus• Involved in motor

output

• Voluntary movement and posture

• Fluid, smooth motion

• Forms portion of lateral wall of 3rd

ventricle

Basal Ganglia

Basal Ganglia

• Globus pallidus• Involved in motor

output

• Voluntary movement and posture

• Fluid, smooth motion

• Primary output of basal ganglia

Basal Ganglia

Basal Ganglia

• Internal capsule• Separates the caudate

from putamen and the globus pallidusand thalamus

• Relay sensory information from thalamus to cortex

• Will become corona radiata (coronal view)

Thalamic Nuclei

• Ventral thalamic nucleus

• Medial geniculate nucleus

• Lateral geniculate nucleus

Thalamic Nuclei

• Ventral thalamic nucleus

• VL

• Input from cerebellum

• Output to motor cortex

• Modulates motor functions

Thalamic Nuclei

• Medial geniculate nucleus

• MGN

• Input from inner ear

• Output to auditory cortex

• Transmits auditory information

Thalamic Nuclei

• Lateral geniculate nucleus

• LGN

• Input from the retina

• Output to the visual cortex

• Transmits visual information

Hippocampus

Amygdala

• Part of the limbic system• Also includes

hippocampus, fornix, cingulate cortex, olfactory bulb, mammillary bodies, striatum

• Regulates emotional behavior
