A set of plastic synapses on a command neuron constitutes a link vector.
Synaptic ribbons or bars are electron dense structures on the presynaptic side of photoreceptor and bipolar cell synapses.
Note that the relative density of immunoreactive processes or terminals may not be directly related to the density of synapses.
If synapses are stabilized by the light exposure, then the second deprivation should have no effect.
This might explain why glutamate released from astrocytes produces such diverse effects on different synapses and cell types.
The fact that the various synaptotagmins are co-expressed in synapses but not co-localized on synaptic vesicles suggests that they may have distinct functions.
In accord, voltage attenuations were severe for synapses located anywhere within 80% of the arbor (>75% loss at the soma).
Thus, adverse postnatal experience could contribute significantly to disordered development; enriching experiences, on the other hand, could potentially facilitate survival of neurons and synapses.
