The striatum has an (excitatory/inhibitory) connection to the globus pallidus external.  Activation of that connection (increases/decreases) activity in the globus pallidus internal, ultimately (promoting/suppressing) movement.Group of answer choicesExcitatory, increases, promotingExcitatory, increases, suppressingInhibitory, decreases, promotingInhibitory, decreases, suppressingInhibitory, increases, suppressing   Is my reasoning correct?   basal ganglia circuitry: The striatum (caudate nucleus and putamen) sends inhibitory projections to the globus pallidus externus (GPe). Therefore, the connection between the striatum and GPe is inhibitory. The GPe sends inhibitory projections to the subthalamic nucleus (STN). The STN sends excitatory projections to the globus pallidus internus (GPi). The GPi, in turn, sends inhibitory projections to the thalamus. When the striatum activates its connection to the GPe (due to receiving excitatory input from the cortex), it inhibits the GPe.…

A second hit might arise because of viral infection. Tumor-initiating viruses often target RB1 for inactivation. What advantage would a virus gain by inactivating RB function in the host cell? Human papillomavirus (HPV) is an example of a virus that inactivates RB and causes tumors. Which cancer is HPV infection most closely associated with? How is HPV able to inactivate RB?
