NeuronCompartmentPropertyConnectivityNotes
Spinal cord L motor neuron alphaSomaI K,Ca.Intracellular recordings: activation by I AHP causes unstable depolarizing plateau potentials; activated and modulated by 5-HT for decending raphe axons (Hounsgaard J and Kiehn O, 1989 [turtle ]24 ). Intracellular recordings: afterhyperpolarization potential inverses during repetitive impulse firing, limiting durations and frequency range of impulse firing (Barrett EF and Barret JN, 1976 [frog ]25 ; discussed in Burke 1998).
