the activity of the magnocellular neurons (mcns) of supraoptic nucleus (son) is regulated by a variety of excitatory and inhibitory inputs. opioids are one of the important compounds that affect these inputs at son synapses. in this study, whole-cell patch clamp recording of son neurons was used to investigate the effect of acute and repeated morphine administration on spontaneous inhibitory an...
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...
We investigated whether capsaicin modulated synaptic transmission to hypoglossal motor neurons (HMNs) by acting on transient receptor potential vanilloid type 1 (TRPV1) receptors. Using whole-cell patch clamp recording from neonatal rat HMNs, we found that capsaicin increased spontaneous excitatory post-synaptic current (sEPSC) frequency and amplitude. Interestingly, the only effect of capsaici...
The time course of synaptic currents is a crucial determinant of rapid signaling between neurons. Traditionally, the mechanisms underlying the shape of synaptic signals are classified as pre- and post-synaptic. Over the last two decades, an extensive body of evidence indicated that synaptic signals are critically shaped by the neurotransmitter time course which encompasses several phenomena inc...

Elucidation of the mechanism of action of the atypical antipsychotic clozapine is complicated by the finding that this molecule interacts with multiple targets including dopaminergic and serotonergic receptors. Binding studies have suggested that clozapine also antagonises GABA(A) receptors, but physiological evidence for such a block at functional synapses is lacking. In this study, we explore...
