Dendritic spine dysgenesis contributes to hyperreflexia after spinal cord injury.

abstract：:1. In Aplysia buccal ganglia, in which dual presynaptic neurons innervate multiple postsynaptic cells, strengths of the same identified synapses differ from animal to animal, consistent with developmental or plastic modulation. Synaptic strengths are specified by the postsynaptic neuron, so that synaptic current ampli...
