McGill University researchers have demonstrated that AMPA receptors (AMPARs), which mediate fast excitatory neurotransmission in the brain fundamental to learning and memory processes, exhibit varying ...

AMPA receptors control excitatory transmission in the central nervous system by converting glutamate release into rapid cation influx and postsynaptic depolarisation. Their gating kinetics and ion ...

In this study, researchers used positron emission tomography and a special tracer to study the relationship between the distribution of an important neuronal receptor (AMPA) and the occurrence and ...

To transmit excitatory signals, nerve cells mostly use glutamate as a neurotransmitter. To detect these transmitter signals, ...

While the COVID pandemic has thankfully been over for some time now, there is still a considerable number of people in the world (about 400 million) suffering from long COVID. Long COVID is a chronic ...

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, used high-speed atomic force microscopy to observe dynamic changes in AMPA receptors, which are vital for brain ...

Synaptic plasticity, the ability of synapses to strengthen or weaken over time in response to changes in their activity, is a central foundation of learning and memory. At synapses, presynaptic cells ...
