Intro to Neuro Question: 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? The striatum has an inhibitory connection to the globus pallidus external (GPe). Activation of that connection decreases activity in the globus pallidus internal (GPi), ultimately promoting movement. Thus, the correct group of answer choices is: Inhibitory, decreases, promoting
