When neuroscientists analyzed the exact properties of nerve connections in the brain, they made a startling observation: At a key connection, or synapse, messages are sent against the usual stream of ...

How do we think, feel, remember, or move? These processes involve synaptic transmission, in which chemical signals are transmitted between nerve cells using molecular containers called vesicles. Now, ...

The synaptotagmin protein family has been studied by neuroscientists for decades. However, most isoforms lack well-defined functions. Now, researchers have identified a crucial, presynaptic role for ...

Interactions of two voltage-gated calcium channels and a pump enable separate control of exocytosis and endocytosis at chemical synapses. Chemical synapses transmit information within the nervous ...

A new type of brain cell, called a glutamatergic astrocyte, has been discovered. It could explain how a variety of neurodegenerative conditions, such as Parkinson’s, develop. Brain cells can largely ...
