sensory neuron

Further receptor-deletion experiments strongly suggested that previously documented changes3,4 in two other key classes of sensory neuron are also involved.

Signals from a sensory neuron can reach nearly any cell within two passes of the electrochemical baton.

Skin’s somatosensory system comprises more than a dozen subtypes of sensory neuron, but only those involved in tactile sensation are well understood.

This single protein molecule can respond to both heat and capsaicin by opening an ion channel, a pore that lets positive ions flow inside, thereby causing the sensory neuron to fire electrical spikes.

Fast, but not as fast as the human nervous system, which can pass a message from a sensory neuron, through several interneurons, to a motor neuron within several milliseconds.
