PRITE NEUROSCIENCE TEST QUESTIONS AND
ANSWERS
26 years old with weeks of R-hand clumsiness and HA. The examination
reveals a moderately dysmetric finger tamping, overt intention tremor on finger-
to-nose, and trouble with quick alternating hand movements. No papilledema
and the CNS is intact. Where will an MRI reveal damage? ANSWER The
cerebellum

striatum
Dopaminergic neurons in addiction project to the nucleus accumbens. Which
part of the brain contains the cell bodies of these neurons? ANSWER region of
the ventral tegmental

mediated by the ability to change shape and number quickly? Dendritic
ANSWER Spines

units

brought on by lesions affecting the cortical-subcortical circuits that connect the
frontal cortex, pons, and what? ANSWER The cerebellum
Which part of the brain is affected by light exposure? ANSWER Nucleus
suprachiasmatic
When does the peak of synaptogenesis occur? The first four years of life
