Attention and arousal

What is the function of the midline (thalamus)?

Attention and arousal

What is the function of the centromedian and intralaminar (thalamus)?

Coordination, helps maintain balance, posture, and equilibrium

What is the function of the cerebellum?

Balance and vesitbulo-ocular reflexes from medial longitudinal fasciculus, involved in the vestibulospinal tract

What is the function of the flocculonodular lobe?

Vestibular nuclei and visual cortex

From where does the flocculonodular lobe receive input?

Vestibular nuclei

Where does the flocculonodular lobe send output to?

Fastigial nucleus

What cerebellar nuclei are involved in the vermis?

Receives input from spinal cord, modulates posture, locomotion, smooth pursuits, and saccades

What is the function of the vermis?

Visual, auditory, vestibular, and somatosensory from neck and proximal body parts

From where does the vermis receive input?

Vestibular nuclei, superior colliculus, cortical motor areas, and motor centers in reticular formation

Where does the vermis send output to?

Interposed nuclei (globus and emboliform)

What cerebellar nuclei are involved in the intermediate zone?

Modulates limbs and digits, feedforward system

What is the function of the intermediate zone?

Somatosensory from limbs and spinal cord

From where does the intermediate zone receive input?

Cortical motor areas and red nucleus

Where does the intermediate zone send output to?

Dentate nucleus

What cerebellar nuclei are involved in the lateral zone?

Planning and mental rehearsal of complex motor actions, regulate thinking and emotions, evaluates sensory inputs

What is the function of the lateral zone?

Cerebral cortex

From where does the lateral zone receive input?

Primary motor cortex and premotor areas, prefrontal cortex, posterior parietal cortex, and red nucleus

Where does the lateral zone send output to?

(Efferent) transmits info to cortex via spinocerebellar tract

What in the function of the superior peduncle?

(Afferent) receives information from cortex and brainstem via corticopontine tract

What in the function of the middle peduncle?

(Afferent) receives information from medulla

What in the function of the inferior peduncle?

Motor control, initiation of voluntary movements, sequencing of movements

What is the function of the basal ganglia?

Sequence and amplitude of movements, regulates subconscious body movements, motor learning

What is the function of the putamen?

Primary and secondary somatosensory cortices, visual cortex, premotor and motor cortices, and auditory association areas

From where does the putamen receive input?

Control of thoughts and eye movements

What is the function of the caudate?

Association cortices and frontal lobe

From where does the caudate receive input?

Major reward stimulus center, feedback with dopamine (can contribute to addictions), regulation of emotions and mood

What is the function of the nucleus accumbens?

Subconscious movement, directly inhibits cerebellum

What is the function of the globus pallidus?

Thalamus (ventral anterior and ventral lateral nuclei)

Where does the globus pallidus send output to?

Eye movements, motor planning, reward system support

What is the function of the substantia nigra?

Thalamus (ventral anterior and ventral lateral nuclei)

Where does the substantia nigra send output to?
