3 good questions and answers about "internal features of the brain"

The fact that low electrical current intensities applied to primary motor cortex can evoke movements what does this indicate
This indicates that the upper motor neurons of this area have relatively direct access to local circuit neuron and lower motor neurons in the brainstem and spinal cord
The commands to move eyes are generated in a similar set of circuits comprising
The frontal eye fields in the cortex and the superior colliculus in the midbrain, which then project to the brainstem reticular formation this organises and coordinates activation of the extracular muscles by lower motor neurons in the brainstem
What is the superior colliculus
An easily accessible layers structure in the midbrain
