Chemical synaptic transmission is subject to modulation by intrinsic and extrinsic factors, including frequency and pattern of AP firing, which can either facilitate or depress the transmission across any given synapse.doi:10.1016/B978-0-12-387738-3.00032-9Janusz B. Suszkiw...
Synaptic transmission is the biological process by which a neuron communicates with a target cell across a synapse. Chemical synaptic transmission involves the release of a neurotransmitter from the pre-synaptic neuron, and neurotransmitter binding to specific post-synaptic receptors. Electrical synapse tra...
Neurons communicate through chemical synapses and electrical synapses (gap junctions). Although these two types of synapses often coexist between neurons, little is known about whether they interact, and whether any interactions between them are importan
forms. We argue that throughout evolution, distinct synaptic constituents have been co-opted from ancestral forms for a new role in earlymetazoan, leading to the rise of chemicalsynapsesandneurotransmission. Such a mosaic model of the origin of chemical synapses agrees with and supports the ...

Electrical synapses often lack the directional specificity of chemical synapses and may transmit a signal in either direction. During biological activity, electrical synapses do not have the potential for as much variation as do chemical synapses. ...
Hitherto the conception of chemical transmission at nerve endings and neuronal synapses, originating in Loewi’s discovery, and with the extension that the work of my colleagues has been able to give to it, can claim one practical result, in the specific, though alas only short, alleviation of...
The release of synaptic transmitter in chemical synapses is brought about by Ca2+ influx through voltage-dependent Ca2+ channels opened by depolarisation of presynaptic terminals. However, due to persistence or increase of transmitter release in low-Ca2+ media in some preparations, it has been propo...
It is impossible to try and state the problems of nerve-muscle transmission without immediately treading on controversial ground. There are physiologists who would even deny that a separate problem of transmission across nerve-muscle, or other synapses, exists distinct from the mechanism of unicellular...
