Basal Junctions at Synaptic Endings of Turtle Visual Cells
It has been often assumed that the first synapse of the visual pathway is confined to the region where the visual cell ending is indented by processes of other retinal elements (4, 9, 15), identified as horizontal and bipolar cells (11, 16). In the vicinity of the indented area, the visual cells contain small vesicles similar to those found at other synapses (3, 13, 14), and dense lamellae are ...
متن کاملEffects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
متن کاملNon-synaptic transmission at autonomic neuroeffector junctions.
Non-synaptic transmission is characteristic of autonomic neuroeffector junctions. The structure of the autonomic neuromuscular junction is described. The essential features are that: the terminal portions of autonomic nerve fibers are varicose and mobile, transmitters being released 'en passage' from varying distances from the effector cells; while there is no structural post-junctional special...
متن کاملSynaptic target recognition at Drosophila neuromuscular junctions.
Every synaptogenesis begins with "synaptic target recognition," a cell-cell recognition event in which a neuron and its target stably adhere. Despite its importance in developing nervous systems, synaptic target recognition has been difficult to study in complex systems. The relatively simple and genetically accessible Drosophila NMJ model system provides a repertoire of target recognition cues...
متن کاملChannelrhodopsin2 mediated stimulation of synaptic potentials at Drosophila neuromuscular junctions.
The Drosophila larval neuromuscular preparation has proven to be a useful tool for studying synaptic physiology. Currently, the only means available to evoke excitatory junctional potentials (EJPs) in this preparation involves the use of suction electrodes. In both research and teaching labs, students often have difficulty maneuvering and manipulating this type of stimulating electrode. In the ...
