Alcohol
Cerebellum and Frontal Cortex

Alpha Motor Neuron

Motor Unit: is an alpha motor neuron and all the fibres it innervates

Motor Neuron pool

Intrafusal Muscle Fibres

Motor Neuron types

cortical motor areas can control alpha motor neurons and the brainstem (higher levels monitoring lower areas)

Tectum (roof of midbrain)

Vestibular spinal tract: 5 accelerometers in ears which land on alpha motor neurons which are set off by gravity. constantly sending a tonic signal to inform you of where you are

Reticulospinal tract
Reticular means web like

Lateral brain stem pathways: GOAL directed movements
not used as much in humans as in animals

Humans have a Lateral Corticospinal tract

M1 Neuroplasticity

PMA lesions

SMA lesions
