Adaptation to Synaptic Inactivity in Hippocampal Neurons
In response to activity deprivation, CNS neurons undergo slow adaptive modification of unitary synaptic transmission. The changes are comparable in degree to those induced by brief intense stimulation, but their molecular basis is largely unknown. Our data indicate that prolonged AMPAR blockade acts through loss of Ca2+ entry through L-type Ca2+ channels to bring about an increase in both vesic...
متن کاملSpinal atypical protein kinase C activity is necessary to stabilize inactivity-induced phrenic motor facilitation.
The neural network controlling breathing must establish rhythmic motor output at a level adequate to sustain life. Reduced respiratory neural activity elicits a novel form of plasticity in circuits driving the diaphragm known as inactivity-induced phrenic motor facilitation (iPMF), a rebound increase in phrenic inspiratory output observed once respiratory neural drive is restored. The mechanism...
متن کاملActivation of inwardly-rectifying k+ channels in hypothalamic POMC neurons: role in integrating synaptic and metabolic input
Hypothalamic proopiomelanocortin (POMC) neurons are critical for controlling homeostatic functions in mammals. We used a transgenic mouse model in which the POMC neurons were labeled with enhanced-green fluorescent protein (EGFP) to perform visualized, whole-cell patch recordings from pre-pubertal female hypothalamic slices. The mouse POMC-EGFP neurons expressed the same endogenous conductance ...

متن کاملA novel subunit for shal K+ channels radically alters activation and inactivation.
Shal (Kv4) potassium channel genes encode classical subthreshold A-currents, and their regulation may be a key factor in determining neuronal firing frequency. The inactivation rate of Shal channels is increased by a presently unidentified class of proteins in both Drosophila and mammals. We have cloned a novel Shal channel subunit (jShalgamma1) from the jellyfish Polyorchis penicillatus that a...
