Effects 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...
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 کاملSelf-modeling structure of evoked postsynaptic potentials.
With the simplicity of the synaptic structure and physiology at neuromuscular junctions (NMJs) of crayfish and the given transmitter being released in quantal packets, a detailed assessment in the fundamental processes of chemical synaptic transmission is possible. Since the quantal event is the basic element of transmission, we consider an approach to further understand the characteristics of ...
متن کاملAgonist-dependent postsynaptic effects of opioids on miniature excitatory postsynaptic currents in cultured hippocampal neurons.
Although chronic treatment with morphine is known to alter the function and morphology of excitatory synapses, the effects of other opioids on these synapses are not clear. Here we report distinct effects of several opioids (morphine, [d-ala(2),me-phe(4),gly(5)-ol]enkephalin (DAMGO), and etorphine) on miniature excitatory postsynaptic currents (mEPSCs) in cultured hippocampal neurons: 1) chroni...
