Vestibulospinal Tract - Viktor`s Notes for the Neurosurgery Resident

... The vestibulospinal tract arises from the lateral vestibular nucleus (Deiters nucleus) and descends ipsilaterally in the lateral funiculus of the spinal cord. Vestibulospinal neurons synapse in laminae VII, VIII, and IX of the spinal cord. Several vestibulospinal fibers synapse directly with α and ϒ ...

Premovement neuronal activity

Premovement neuronal activity in neurophysiological literature refers to neuronal modulations that alter the rate at which neurons fire before a subject produces movement. Through experimentation with multiple animals, predominantly monkeys, it has been shown that several regions of the brain are particularly active and involved in initiation and preparation of movement. Two specific membrane potentials, the bereitschaftspotential, or the BP, and contingent negative variation, or the CNV, play a pivotal role in premovement neuronal activity. Both have been shown to be directly involved in planning and initiating movement. Multiple factors are involved with premovement neuronal activity including motor preparation, inhibition of motor response, programming of the target of movement, closed-looped and open-looped tasks, instructed delay periods, short-lead and long-lead changes, and mirror motor neurons.
