Examples of presynaptic

presynaptic
Positive values denote postsynaptic to the middle of the cleft; negative values denote presynaptic to the middle of the cleft.

Only regions containing presynaptic ribbons were examined at high magnification and analyzed for labeling.
Presynaptic specificity of endocannabinoid signaling in the hippocampus.
Indeed, horizontal cell endings in the synaptic triad contain small numbers of small, clear-core vesicles, though they lack conventionally defined presynaptic membrane specializations.
This defect could be either presynaptic or postsynaptic.
In addition, methacholine may have different effects at presynaptic and postsynaptic sites.
A portion of the transmitters (factor r) returns from the synaptic cleft into the presynaptic hair cell.
Our aim is now to try to genetically block these presynaptic events to see if this influences disease progression.
To test the interactions between cones and horizontal cells, the linearity functions were compared for presynaptic-postsynaptic cell pairs according to the cascade model.
Thus, although neurotrophins modulate the formation of presynaptic axon terminals, the precise cellular and molecular mechanisms remain to be determined.
The computation of directional selectivity in the retina occurs presynaptic to the ganglion cell.
The mechanisms by which neurotrophins enhance the formation and function of presynaptic terminals remain unclear.
