Development of calcium-permeable AMPA receptors and their correlation with NMDA receptors in fast-spiking interneurons of rat prefrontal cortex.
Abnormal influx of Ca(2+) is thought to contribute to the neuronal injury associated with a number of brain disorders, and Ca(2+)-permeable AMPA receptors (CP-AMPARs) play a critical role in the pathological process. Despite the apparent vulnerability of fast-spiking (FS) interneurons in neurological disorders, little is known about the CP-AMPARs expressed by functionally identified FS interneu...
متن کاملTonic NMDA receptor-mediated current in prefrontal cortical pyramidal cells and fast-spiking interneurons.
Tonically activated neuronal currents mediated by N-methyl-d-aspartate receptors (NMDARs) have been hypothesized to contribute to normal neuronal function as well as to neuronal pathology resulting from excessive activation of glutamate receptors (e.g., excitotoxicity). Whereas cortical excitatory cells are very vulnerable to excitotoxic insult, the data regarding resistance of inhibitory cells...
متن کاملMechanisms of dopamine activation of fast-spiking interneurons that exert inhibition in rat prefrontal cortex.
Prefrontal cortical dopamine (DA) modulates pyramidal cell excitability directly and indirectly by way of its actions on local circuit GABAergic interneurons. DA modulation of interneuronal functions is implicated in the computational properties of prefrontal networks during cognitive processes and in schizophrenia. Morphologically and electrophysiologically distinct classes of putative GABAerg...
متن کاملPostnatal development of 2 microcircuits involving fast-spiking interneurons in the mouse prefrontal cortex.
Disturbed development of the parvalbumin-positive fast-spiking (FS) interneurons in the prefrontal cortex (PFC) is closely associated with many neuropsychiatric disorders such as schizophrenia and autism. FS interneurons form at least 2 microcircuits in the PFC: one with pyramidal neurons (FS-PN) through chemical synapses; the other with other FS interneurons (FS-FS) via chemical and electrical...
متن کاملDopaminergic modulation of short-term synaptic plasticity in fast-spiking interneurons of primate dorsolateral prefrontal cortex.
Dopaminergic regulation of primate dorsolateral prefrontal cortex (PFC) activity is essential for cognitive functions such as working memory. However, the cellular mechanisms of dopamine neuromodulation in PFC are not well understood. We have studied the effects of dopamine receptor activation during persistent stimulation of excitatory inputs onto fast-spiking GABAergic interneurons in monkey ...
