Nonlinear behavior of muscle reflexes at the human ankle joint.

abstract：:The neuromodulator acetylcholine (ACh) shapes neocortical function during sensory perception, motor control, arousal, attention, learning, and memory. Here we investigate the mechanisms by which ACh affects neocortical pyramidal neurons in adult mice. Stimulation of cholinergic axons activated muscarinic and nicotinic...

Although it is generally agreed that Ca2+ couples depolarization to the release of neurotransmitters, hypertonic saline and ethanol (ETOH) evoke neurosecretion independent of extracellular Ca2+. One possible explanation is that these agents release Ca2+ from an intracellular store that then stimulates Ca(2+)-depend...
