The activation of olfactory receptors results in olfactory receptor neurons sending an impulse to the brain’s olfactory system.

This is why the response is so fast. Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal ...

Sensory neurones carry electrical signals - nerve impulses - towards the central nervous system (spinal cord and brain). The signal starts in a receptor ... The neurone ends in either a muscle ...

Expression of the alpha2delta1 receptor in sensory neurons increased as they over-secreted a neuropeptide called CGRP, all ...

New research has shown that some neurons that do not express leptin receptors are still sensitive to its activity.

When this receptor is overactivated, external sensory input is suppressed, and the brain generates more internally-driven images. "It's a bit like our brain is increasingly talking to itself ...
