WebMay 1, 2003 · Typical cholinergic preganglionic terminals were numerous in all species. To ensure positive identification of adrenergic nerve terminals, some animals were pretreated with 5-hydroxydopamine. WebSynaptic plasticity is defined as the ability of synapses to change their strength of transmission. Plasticity of synaptic connections in the brain is a major focus of neuroscience research, as it is the primary mechanism underpinning learning and memory. Beyond the brain however, plasticity in peripheral neurons is less well understood, particularly in the …
Analysis of non-noradrenergic/non-cholinergic (NANC) transmission at single varicosities or swellings indicates that individual synapses possess different probabilities for the secretion of transmitter as well as different complements of autoreceptors and mixtures of post-junctional receptor … See more A neuroeffector junction is a site where a motor neuron releases a neurotransmitter to affect a target—non-neuronal—cell. This junction functions like a synapse. However, unlike most neurons, somatic efferent motor … See more In the peripheral nervous system, local junctional transmission was recognized in the late 1960s and early 1970s. Until then, all chemical neurotransmission was thought to involve synapses and the innervations of tissue were considered synonymous with … See more Non-synaptic transmission is characteristic of autonomic neuroeffector junctions. The essential features are that: the terminal portions of autonomic nerve fibers are varicose and mobile; transmitters are released from varicosities at varying distances from the … See more Neuromuscular junctions in gastrointestinal (GI) smooth muscles may reflect innervation of, and post-junctional responses in, all three classes of post-junctional cells.
