Noradrenergic System Increases Miniature Excitatory Synaptic Currents in the Barrel Cortex
Introduction: Neurons in layer II and III of the somatosensory cortex in rats show high frequency (33 ± 13 Hz) of miniature excitatory postsynaptic currents (mEPSCs) that their rates and amplitudes are independent of sodium channels. There are some changes in these currents in neurodegenerative and psychological disorders. Regarding to well known roles of the neuromodulatory brain systems in...
متن کاملMiniature synaptic currents become neurotoxic to chronically silenced neurons.
When deprived of spontaneous ongoing network activity by chronic exposure to tetrodotoxin (TTX), cultured cortical neurons retract their dendrites, lose dendritic spines, and degenerate over a period of 1-2 weeks. Electrophysiological properties of these slowly degenerating neurons prior to their death are normal, but they express very large miniature excitatory postsynaptic currents (mEPSCs). ...

متن کاملMiniature Excitatory Junction Potentials
Neuromuscular transmission of excitation in invertebrates has been studied extensively by many investigators (cf. Bullock & Horridge, 1963). Miniature inhibitory junction potentials (m.i.j.p.s) and miniature excitatory junction potentials (m.e.j.p.s) could be recorded from the longitudinal layer of the somatic muscle in the earthworm. Field stimulation to the peripheral nerves elicited inhibito...
متن کاملA new analytical method of studying post-synaptic currents.
A powerful methodology for analyzing post-synaptic currents recorded from central neurons is presented. An unknown quantity of transmitter molecules released from presynaptic terminals by electrical stimulation of nerve fibers generates a post-synaptic response at the synaptic site. The current induced at the synaptic junction is assumed to rise rapidly and decay slowly with its peak amplitude ...
