Slow synaptic transmission in frog sympathetic ganglia.
Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs. The sEPSP reflects a muscarinic action of acetylcholine released from boutons on B cells, whereas the late sEPSP is caused by a peptide (similar to teleost LHRH) released ...
متن کاملNoradrenergic 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 کاملVoltage clamp study of fast excitatory synaptic currents in bullfrog sympathetic ganglion cells
Excitatory postsynaptic currents (EPSCs) have been studied in voltage-clamped bullfrog sympathetic ganglion B cells. The EPSC was small, rose to a peak within 1-3 ms, and then decayed exponentially over most of its time-course. For 36 cells at --50 mV (21-23 degrees C), peak EPSC size was --6.5 +/- 3.5 nA (mean +/- SD), and the mean decay time constant tau was 5.3 +/- 0.9 ms. tau showed a small...

متن کاملEffects of Ketamine on Neuronal Spontaneous Excitatory Postsynaptic Currents and Miniature Excitatory Postsynaptic Currents in the Somatosensory Cortex of Rats
Background: Ketamine is a commonly used intravenous anesthetic which produces dissociation anesthesia, analgesia, and amnesia. The mechanism of ketamine-induced synaptic inhibition in high-level cortical areas is still unknown. We aimed to elucidate the effects of different concentrations of ketamine on the glutamatergic synaptic transmission of the neurons in the primary somatosensory cortex b...
