Rhythmic firing
WebbCardiac rhythm is a prominent feature of the autonomic control system, present on different levels, including neuron activity in central circuits. The mechanism of rhythmic … Webb1 aug. 1998 · Because of the large currents needed to evoke rhythmic firing and because some of the cells were studied using single-electrode voltage-clamp techniques (see Lee and Heckman 1998 ), resistances of the electrodes were kept low—typically ∼4–6 MΩ in saline before entering the cord.

WebbWe apply dynamical systems methods to understand transitions between irregular and rhythmic firing in an excitatory-inhibitory neuronal network model. Using the geometric theory of singular perturbations, we systematically reduce the full model to a simpler set of equations, one that can be studied analytically.
Webb13 sep. 2005 · I have read there are two types of fasics: spontaneous ones that fire with no relation to contraction of muscles and the contraction ones: which are rhythmic firing of motor unit - observed during weak contraction. The latter are seen in ALS and a compression of nerve root. My question is: 1. So, are there two kinds of fasics. northern monitor warrantyWebbThere are several types of epileptiform activity, including single discharges (sharps and spikes) and rhythmic and/or periodic activity.
