The cerebellum of cartilaginous and bony fishes is extraordinarily large and complex. In at least one important respect, it differs in internal structure from the mammalian cerebellum: The fish cerebellum does not contain discrete deep cerebellar nuclei. Instead, the primary targets of Purkinje cells are a distinct type of cell distributed ...
The cerebrum is a major part of the brain, controlling emotions, hearing, vision, personality and much more. It controls all precision of voluntary actions, and it functions as the center of sensory perception, memory, thoughts and judgement; the cerebrum also functions as the center of voluntary motor activities.
The dentate nucleus is responsible for the planning, initiation and control of voluntary movements. The dorsal region of the dentate nucleus contains output channels involved in motor function, which is the movement of skeletal muscle , while the ventral region contains output channels involved in nonmotor function, such as conscious thought ...
The cerebellum is a high potential target for neuromodulation of neurological and psychiatric disorders due to the high density of neurons in its superficial layer, its electrical properties, and its participation in numerous closed-loop circuits involved in motor, cognitive, and emotional functions.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
This indicates that when chronic use damages the prefrontal cortex, the importance of the cerebellum to external incentive stimuli increases. This drug-induced damage of fronto-cerebellar circuitry may result in the cerebellum taking a larger role in long-term emotional memory, behavioral sensitization, and inflexible behavior. [9]
A woman exercising. In physiology, motor coordination is the orchestrated movement of multiple body parts as required to accomplish intended actions, like walking.This coordination is achieved by adjusting kinematic and kinetic parameters associated with each body part involved in the intended movement.
This sensory input, while processed, does not necessarily cause conscious awareness of the action. Closed loop control [24]: 186 is a feedback based mechanism of motor control, where any act on the environment creates some sort of change that affects future performance through feedback. Closed loop motor control is best suited to continuously ...
