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 ...
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 ...
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 ...
Researchers have shown that as flies encounter an odor signal, the specific pattern of interference between olfactory receptors helps flies quickly compute the “gist” of the odor’s meaning.
Experts agree that problems with synapses—the connections that allow communication between neurons—might be a ... a solution to this problem. As AMPA receptors are one of the most important ...
Researchers from the lab of Richard Simerly have uncovered the first example of activity-dependent development of hypothalamic neural circuitry. The work also suggests a novel role for the hunger ...
