Volume transmission (VT) is a widespread mode of intercellular communication that occurs in the extracellular fluid (ECF) and in the cerebrospinal fluid (CSF) of the brain with VT signals moving from source to target cells via energy gradients leading to diffusion and convection (flow). The VT...
receptor activation as they generate massive spatiotemporal transmitter gradients. The detection of seemingly constant ambient levels arises from low sampling frequency and large collection volumes, and they are composed of highly dynamic signals even at baseline, as we recently discussed for dopamine [...
Preliminarily, we analysed three integrated visual cortex scRNA-seq databases from mouse, macaque and human, and confirmed the presence of a subpopulation of glutamatergic astrocytes (Methods and Extended Data Fig. 7c). We next imaged SF-iGluSnFR signals in awake mice, using acute cranial windows...
(8) These are located, not only centrally, but also peripherally in the skin, muscles, and knee joints and play a role in central nociceptive transmission, modulation, and sensitization of acute pain states as well as in the sensory transmission of noxious signals. The effect of minerals on ...
The transmission of synaptic signals is mediated by chemicalneurotransmittersubstances.Neurotransmittersare synthesized inpresynaptic terminalsand stored insynaptic vesicles.Transmitter releaseis evoked by presynaptic action potentials (APs), which activate influx of Ca2+into terminals and trigger a Ca2+-dependen...
