You are examining a primitive vertebrate and want to determine whether the same part of its brain coordinates muscular movement as in the human brain, so you would do a surgical experiment to disconnect the rest of the brain from the

cerebellum

Explanation:

The basal ganglia and cerebellum of the first floor provide basic movement control and store many of our primitive reactions, as well as many of the learned programs that have become automatic. Right next to them is the limbic system, hence the close relationship between emotions and movements, and the feelings linked to the emotional consequences of our actions. This explains why they can accompany emotional changes to certain ailments that are related to the movement; For example, it is not uncommon for depression to accompany Parkinson's disease.

The cerebellum, on the first floor, is primarily responsible for balance, posture and coordination. As thanks to him we can move the attention rhythmically, he has a great participation in most systems, if not all. Cerebellum means in Latin "cerebrito", and sometimes it seems as if he has his own mind. Information regarding the movement and position of the body enters the cerebellum, where it is processed. Instructions are then sent to modify posture and coordinate muscle movements. This has a more fundamental importance than it may seem. In order for the movements to take place, the brain must know the position and speed of the body and each limb, and where you are in space and time. Spatial orientation and posture are essential to know "where you are." The only reason that you remain upright and gravity does not make you fall is the constant monitoring of the cerebellum. It adjusts the reactive changes of the posture in the brainstem, which sends spinal cord messages down, which control the muscles that straighten and extend the trunk and limbs and fight against the force that pulls down.

On the second floor are the motor and premotor cortices, which control things such as specialized movements of the face and extremities, in particular the manipulation movements in which the arm, hand and fingers participate. Good evidence of the extensive interconnection and feedback between the different plants can be seen by studying the effects of the motor cortex.
