Expand description

Alpha motor neuron — spinal cord, innervates extrafusal muscle fibres.

Biophysics: Wang-Buzsáki Na+/K+ core, persistent inward current (PIC) for bistable firing (plateau potentials), Ca2+-dependent AHP for rate limiting (f-I gain control). Larger soma than cortical neurons → lower input resistance.

PIC is modelled as a slow L-type Ca2+ current that activates at depolarised potentials and inactivates very slowly, enabling plateau potentials and self-sustained firing after brief input.

AHP from Ca2+-activated K+ (SK channels) limits firing rate and produces the characteristic linear f-I relationship of motor neurons.
