Outward currents influencing bursting dynamics in guinea pig trigeminal motoneurons.
To initiate and maintain bursts (and plateau potentials) in the presence of serotonin, guinea pig trigeminal motoneurons utilize L-type Ca2+ and persistent Na+ inward currents. However, the intrinsic currents that contribute to burst termination and determine the duration of the interburst interval are unknown. Therefore we investigated the roles of outward currents, whose slow activation is co...
متن کاملInfluence of active dendritic currents on input-output processing in spinal motoneurons in vivo.
The extensive dendritic tree of the adult spinal motoneuron generates a powerful persistent inward current (PIC). We investigated how this dendritic PIC influenced conversion of synaptic input to rhythmic firing. A linearly increasing, predominantly excitatory synaptic input was generated in triceps ankle extensor motoneurons by slow stretch (duration: 2-10 s) of the Achilles tendon in the dece...
متن کاملEvaluation of the effect of dendritic branching on signal processing in hippocampus pyramidal cells
Since branching region of an active nerve fiber is an abrupt widening of the structure, two concepts emerge: first, the stimulating current must be sufficient to raise the outgrowing fibers above the thresh¬old, and secondly, the stimulating current will be divided in proportion to the characteristic admittance of the branches. On the other hand, blocking of the nerve impulse in this region is ...

متن کاملTemperature and Dendritic Response of Spinal Motoneurons.
Well-established are the facts that the dendrites of spinal motoneurons carry impulses, at least in the cellulifugal sense, and that they do so with a decrement. 1-4 Whether or not they do these things in the cellulipetal sense is not a matter of present, concern. The experiments to be discussed relate to "antidromic" conduction in dendrites of spinal motoneurons of the cat and the influence up...
