Recent physiological work has used quantal analysis to investigate the properties of synaptic transmission and long-term potentiation in hippocampal area CA1. These analyses have revealed changes in the strength of excitatory post-synaptic responses following long-term potentiation that could be mediated by cellular mechanisms in the presynaptic element, in the postsynaptic element, or in both elements. In these studies, either minimal stimulation, presumably involving a single presynaptic axon… CONTINUE READING

AxonSibling in is aDendrites
An " apposition " was defined as a point where the axons and dendrites crossed in the same focal plane and therefore were sufficiently close to allow a dendritic spine to reach the axon and possibly establish a synaptic contact .
Two adjacent boutons of the same axon could also be found to synapse with different spines of the same dendrite .
An additional 4% of the axons wound back and forth across individual dendrites , possibly forming multiple synapses closely spaced along the dendrites .
An additional 4% of the axons wound back and forth across individual dendrites , possibly forming multiple synapses closely spaced along the dendrites .
Light microscopic analyses of Golgi preparations revealed that about 20% of the axons occurring in stratum radiatum come into close apposition with two to four different dendrites of a target CA1 cell .
