Atypical properties of release and short-term depression at a specialized nicotinic synapse in the Mauthner cell network.
Many synapses exhibit temporally complex forms of activity-dependent short-term synaptic plasticity. The diversity of these phenomena reflects the evolutionary specialization of synapses within networks. We examined the properties of transmission and plasticity, in vivo, at an identified, specialized axo-axonic nicotinic synapse between the goldfish Mauthner cell and one of its targets, the cra...
متن کاملalpha-Bungarotoxin labeling and acetylcholinesterase localization at the Mauthner fiber giant synapse in the hatchetfish.
Autoradiographic and histochemical techniques have been used to characterize further the pharmacology of transmission at the Mauthner fiber giant synapse of the South American hatchetfish. [125I]alpha-Bungarotoxin was applied to hatchetfish medullae and a standard autoradiographic procedure was carried out on 3- to 4-microns sections of glutaraldehyde-fixed tissue. All Mauthner fiber giant syna...
متن کاملPostsynaptic Modulation the Mauthner Cell Synaptic Efficacy Mixed Synapses
Extracellular application of dopamine in the synaptic bed of the lateral dendrite of the goldfish Mauthner (M-) cell enhances both the electrical and chemical components of the mixed excitatory postsynaptic potential (EPSP) evoked by ipsilateral eighth nerve stimulation (Pereda et. al., 1992). We describe here results of experiments designed to determine the locus of action of dopamine and the ...
متن کاملThe octavolateralis system and Mauthner cell: interactions and questions.
This paper is an overview of some of the major points to arise in the accompanying contributions of this special symposium issue. The symposium papers arose out of discussions among investigators interested in the inner ear and Mauthner cell, with the focus on hydrodynamic components that activate the Mauthner cell through the octavolateralis system. The intention of the symposium was to invest...
متن کاملExcitability Changes of the Mauthner Cell during Collateral Inhibition
Excitability changes during collateral inhibition of the goldfish Mauthner cell (M cell) were measured directly by stimulating the cell with current pulses applied through an intracellular electrode. Excitability was suppressed during the extrinsic hyperpolarizing potential (EHP) as well as during the collateral IPSP. The inhibitory effect of the EHP was shown to be comparable in intensity to t...
