The M-current (I(K(M))) is believed to modulate neuronal excitability by producing spike frequency adaptation (SFA). Inhibitors of M-channels, such as linopirdine and 10,10-bis(4-pyridinylmethyl)-9(10H)-anthracenone (XE991), enhance depolarization-induced transmitter release and improve learning performance in animal models. As such, they are currently(More)
Non-adapting superior cervical ganglion (SCG) neurones with a clustering activity and sub-threshold membrane potential oscillations were occasionally recorded, suggesting the presence of a persistent sodium current (I NaP). The perforated-patch technique was used to establish its properties and physiological role. Voltage-clamp experiments demonstrated that(More)
The basis of rhythmic activity observed at the dorsal column nuclei (DCN) is still open to debate. This study has investigated the electrophysiological properties of isolated DCN neurones deprived of any synaptic influence, using the perforated-patch technique. About half of the DCN neurones (64/130) were spontaneously active. More than half of the(More)
Spontaneous and rhythmic neuronal activity in dorsal column nuclei has long been identified in anesthetized cats. Here, we have studied the spontaneous behavior of cuneate cells in anesthetized rats through extracellular recording, showing that most cuneate neurones recorded (155 of 185) fired spontaneously. Overall, 74% of these spontaneously firing(More)
