NSC 4366 1st Edition Lecture 12Outline of Last Lecture I. Basal GangliaOutline of Current Lecture II. Cerebellum-cerebellum sits on top of the pons-cerebellar peduncle is just fiberbundles• -inputs arrive at the cerebellar cortex• -cortex works its magic and projects to deep nuclei• -deep nuclei provide the cerebellar outputThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-anterior lobe is in the frontflocculonodular lobe came first evolutionarily-longitudinal (from side to side): -vermis is the midline structure-paravermis (paramedian) is lateral to the vermislateral zone is involved in motor skills of the hand (skilled movement) (biggest part in cerebellum)vermis invoved in trunk (balance)paravermis involved in proximal limbs (biceps, triceps, quads, hamstrings) - someone with paravermal dysfunction would not be able to walk rightflocculonodular - controls trunk (body posture) and eye movements(if someone has body posture problems they also have eye movement problems) (involves rubrospinal tract, vestibulospinal tract)Anterior love - regulates movement of legsdentate nucleus - lateral cerebellum - fine movement of the handsparavermis - intermediate nucleusvermis - fastigial nuceustwo inputs, one outputgreen input (inferior cerebellar peduncle) - spinal cord talks to cerebellum via the inferior cerebellar peduncle - incoming info from spinal cord and medullagold input (middle cerebellar peduncle) - transverse fibers going from pons to nucleusthe cortex talks to the cerebellum indirectly; cortex sends information down to pontine nuclei in the middle cerebellar peduncle and that’s how it communicates to the cerebellum (if you had a pontine stroke you would lose input to
