Journal ArticleDOI
Direct modulation of the secretory machinery underlies PKA-dependent synaptic facilitation in hippocampal neurons.
TL;DR: The data indicate that PKA causes synaptic facilitation by directly elevating the probability of exocytosis of individual vesicles in response to an invariant Ca2+ signal.
Journal ArticleDOI
Neuronal survival or death after dendrite transection close to the perikaryon: correlation with electrophysiologic, morphologic, and ultrastructural changes.
TL;DR: It is concluded that, in the model system used, neuronal survival after dendrite amputation depends on physical parameters of the lesion that determine the magnitude of the injury current reaching the soma.
Journal ArticleDOI
Calcium-independent activation of the secretory apparatus by ruthenium red in hippocampal neurons: a new tool to assess modulation of presynaptic function
TL;DR: It is reported that the polyvalent cation ruthenium red (RR) directly evokes rapid and reversible calcium-independent quantal secretion in hippocampal neurons by binding to external sites on the presynaptic terminal membrane.
Journal ArticleDOI
The sequence of ultrastructural changes in cultured neurons after dendrite transection
TL;DR: Cultured mouse spinal neurons were fixed at three different intervals after dendrite amputation: within the first 15 min, at 2 h and at 24 h, hypothesized to be the result of an increase in the intracellular concentrations of free calcium.
