The vestibulocerebellum/flocculonodular lobe does?
maintenance of equilibrium
monitors and adjusts vestibular reflexes
The vestibulocerebellum/flocculonodular lobe important in control of?
eye stability and movements for optimal vision
Flocculus coordinates tracking movements of the eyes and can?
suppress the VOR when appropriate
The vestibulocerebellum reciprocal connections with?
vestibular nuclei via inferior cerebellar peduncle
The vestibulocerebellum receives direct input from the?
vestibular appraatus
The vestibulocerebellum receives input from the?
visual system
The vermis and paravermis/medial hemisphere compares motor plan and actual movement. Makes anticipatory and corrective adjustments of movements in?
progress
-Activity increases during movement
The vermis and paravermis/medial hemisphere indirect input from collaterals of?
contralateral corticospinal neurons via pontine nuclei
-provides information on the intended movement
The vermis and paravermis/medial hemisphere extensive inputs from?
ipsilateral spinal cord
The vermis and paravermis/medial hemisphere are in the?
posterior spinocerebellar tract
cuneocerebellar pathways
-provides information on the actual movement in progress
The vermis influence predominately?
axial and girdle muscles for postural adjustments
The vermis works with vestibulocerebellum in?
controlling eye stability
-posterior vermis is a limbic area
The vermal output via the inferior cerebellar peduncles is the vestibular nuclei and reticular formation to influence?
vestibulospinal tracts
reticulospinal tracts
The vermal output via superior cerebellar peduncles is the reticular formation to influence?
corticospinal tracts
Paravermis/medial hemisphere coordinates gross limb?
movements (not fine movements of the fingers/thumb)
Paravermis/medial hemisphere coordinates muscles of?
speech
Paravermis/medial hemisphere coordinates inter-joint lower extremity movement during?
gait
Paravermal/medial hemisphere output via superior cerebellar peduncle - contralateral red nucleus in midbrain to influence?
rubrospinal tract
Paravermal/medial hemisphere output via superior cerebellar peduncle - contralateral ventral lateral nucleus of the thalamus to influence
corticospinal and corticobrainstem tracts
Lateral Hemisphere planning and programming of?
voluntary movements
Lateral hemisphere timing and sequencing of muscle contraction and relaxation to achieve smooth?
voluntary goal-directed movements
-activated prior to activation of corticospinal and corticobrainstem tracts
Lateral hemisphere coordination of limbs for fine movements, including the?
hand, fingers and thumb
Lateral hemisphere motor learning and storage of sequential components of?
skilled motor programs
ex: playing an instrument
Lateral hemisphere cognitive functions?
posteriorly
-language = verb generation and higher order languge tasks
