Synaptic actions of identified peptidergic neuron R15 in Aplysia. I. Activation of respiratory pumping.
The purpose of the study described in this and the following two companion papers was to determine the synaptic actions of neuron R15, an endogenously bursting neurosecretory cell in Aplysia, as a step toward determining its physiological function. The results described in this paper demonstrate that activity in R15 increases the frequency of bursting in the R25/L25 network that triggers respir...
متن کاملSynaptic Actions of Identified Peptidergic Neuron Activation of the Large Hermaphroditic Duct R 15 in Aplysia
The purpose of the study described in this and the preceding two companion papers was to determine the synaptic actions of neuron R 15, an endogenously bursting neurosecretory cell in Aplysia, as a step toward determining its physiological function. The results described in this paper demonstrate that activity in R15 activates anterograde peristaltic movements in the segment of the large hermap...
متن کاملSynaptic actions of identified peptidergic neuron R15 in Aplysia. II. Contraction of pleuroabdominal connectives mediated by motoneuron L7.
The purpose of this study was to determine the synaptic actions of the bursting peptidergic neuron R15 in Aplysia. R15 is known to be excited by the neuroendocrine bag cells, which trigger egg laying. In the two companion papers, we show that R15 mediates some of the effects of the bag cells on respiratory and reproductive organs. In this paper, we demonstrate that R15 excites L7, a multimodal ...
متن کاملModulatory synaptic actions of an identified histaminergic neuron on the serotonergic metacerebral cell of Aplysia.
Possible sources of excitatory synaptic input to the serotonergic metacerebral cell (MCC) were determined by stimulating various neurons in the cerebral ganglion. Firing of the previously identified histaminergic neuron C2 was found to produce synaptic input to the MCC. The synaptic input consists of fast excitatory-inhibitory synaptic potentials on a background of a slow EPSP. The slow EPSP ap...
متن کاملDecreased Response to Acetylcholine during Aging of Aplysia Neuron R15
How aging affects the communication between neurons is poorly understood. To address this question, we have studied the electrophysiological properties of identified neuron R15 of the marine mollusk Aplysia californica. R15 is a bursting neuron in the abdominal ganglia of the central nervous system and is implicated in reproduction, water balance, and heart function. Exposure to acetylcholine (...
