New research from MIT suggests that astrocytes - long considered support cells - may play a key role in the human brain's ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and ...

Sites of presynaptic neurotransmitter release are tightly correlated with the postsynaptic expression of cognate neurotransmitter receptors. At the same time, many neurons express more than one ...

Abstract: Neurotoxins can be divided into presynaptic neurotoxins and postsynaptic neurotoxins based on their mechanism of action. The two neurotoxins have important application in basic research and ...

Neuroligin-1 (Nlgn1) is a postsynaptic cell-adhesion protein exclusively localised to excitatory synapses that is crucial for coordinating the transsynaptic alignment of presynaptic release sites with ...

However, whether and how presynaptic adhesion molecules trans-synaptically regulate the localization and stabilization of postsynaptic neurotransmitter receptors remained largely unclear.

As nicely summarized by one of the reviewers, the authors investigated the role of the presynaptic protein PTPσ, a LAR-type receptor phosphotyrosine-phosphatase, as a transsynpatic regulator of ...

Each of these levels covers a different scenario that can occur between the presynaptic and postsynaptic cell, such as spatial summation or coincidence potentiation. Using their knowledge of these ...
