SHENZHEN -- Chinese scientists have, for the first time, confirmed the existence of microglia in the peripheral nervous ...

Receptor cells detect a change in the environment (a stimulus) and start electrical signals along neurons. These move towards the central nervous system (CNS). The CNS is the brain and spinal cord.

Information from receptors passes along neurones, as electrical impulses to co-ordinators such as the central nervous system or CNS. The CNS is the brain and spinal cord. Muscles contracting or ...

The somatic system contains sensory and motor neurons. It sends and receives ... are responsible for carrying signals between ...

The nervous system consists of the central nervous system (brain and spinal ... of the Drosophila visual system classifies about 53,000 neurons into 732 types. The shapes and connections of ...

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory. Ashley started at The Scientist in 2018. Before joining ...
