Q1 Where do neurons in this nucleus synapse? ANS Cerebellar nuclei and cerebellar cortex Q2 What class of cerebellar afferent originates from the marked nucleus? ANS Climbing fibers Q3 From what brain region do neurons in the marked nucleus receive their input? And to which deep nucleus do they synapse (A, B, C, D, E, or F)? ANS Ipsilateral cerebral cortex - D, E, F, but mostly F Q4 What are the major targets of axons at the tip of the pointer? ANS Red nucleus and VA/VL Q5 Name a motor control function of the marked nucleus. ANS Coordination of head and eye movements. Q6 Name one region where neurons in the marked nucleus synapse. ANS Motor cortex, premotor cortical regions (mostly premotor cortex proper) Q7 In what brain division (medulla, pons, midbrain, diencephalon, cerebral hemisphere) do axons in the marked tract decussate? ANS Midbrain Q8 From which of the labeled regions do the pontine nuclei receive a synaptic input? ANS All of the regions Q9 Does information carried in the marked tract flow into or out of the cerebellum? ANS Into the cerebellum Q10 What are the different projections of the magnocellular and parvocellular divisions of the marked nucleus? ANS The magnocellular division projects to the contralateral spinal cord; the parvocellular division projects to the ipsilateral inferior olivary nucleus.
