The cerebellum sends projections to the cortical motor systems via the [BLANK] and [BLANK].

You are recording from a neuron in the CNS of a monkey that fires spikes during a certain voluntary hand motion. However, you notice that the neuron also fires when the monkey watches another monkey do the same motion, and only that motion. Where would you expect to find this neuron?

Negative feedback for muscle contraction is provided by:

In Parkinson’s disease, dopaminergic input from the _______ decreases.

If a researcher were to stimulate dopamine releasing neurons that project solely to the direct pathway, which of the following would occur? 

The deep excitatory loop in the cerebellum:

LTD is a critical part of motor learning and the three key cerebellum elements involved are Purkinje cells, climbing fibers (CF) and parallel fibers (PF). See attached figure. Which one of the following statements is true regarding LTD in this local microcircuit?

Exogenous electrical stimulation of individual neurons in the motor cortex of a healthy macaque monkey could lead to the following:

Related to the attached images from two different patients, what substance was taken in high doses that led to cell death in image shown on the right?
