They also have not yet defined a physiological function of Aβ on glutamate receptors vis-a-vis an age- or disease-related one, or reached consensus on pre- versus postsynaptic generation of Aβ. α7 ...

How an electrical signal crosses that synaptic gap is not yet entirely understood, but the basic process seems to go like this: a presynaptic neuron receives a message that it has information to ...

Contribute to many important brain functions. Gap junctions operate in parallel with the more classic, synaptic neuronal connections in the brain. This discovery gives the researchers a new model for ...

Using both behavioral and electrophysiological readouts, Channelrhodopsin-2, a light-gated cation channel, is applied to the study of synaptic function in Caenorhabditis elegans. We introduce ...

The natural need for sleep and the brain's synaptic function are closely linked, according to a pair of studies in mice, which suggest that sleep deprivation may also deprive the brain of key ...

The same kind of neurons can have completely different wiring diagrams in the rat and mouse, as mice lack intercellular molecular channels known as gap junctions, researchers at Karolinska Institutet ...
