Sensory systems are composed of receptors that sense the sensory stimuli, brain areas involved in sensory perception and neural pathways that connect them. The microanatomy of the axonal ...

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 ...

The modern study of human perception is not well reflected in the traditional textbook coverage of sensory receptors (retina, cochlea, corpuscular dendrites of the skin), sensory modalities (seeing, ...

These cells never come in contact with environmental signals like those near the skin but are studded with receptors that appear to get sensory input from hormones, proteins and other biochemical ...

There are three main types of neurone: sensory, motor and relay ... Information from receptors passes along neurones, as electrical impulses to co-ordinators such as the central nervous system ...

As AMPA receptors are one of the most important molecules ... activity might be responsible for disrupting the process of sensory perception, which may be the cause of external sensory information ...

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

N-methyl D-aspartate (NMDA) receptors are ligand-gated cation channels activated by glutamate, an excitatory neurotransmitter. These receptors are located mostly at excitatory synapses and ...
