Depolarized neutrons shall also be monitored; they are not stored magnetically, but can still be collected when the inner walls of the trap are covered with a neutron reflecting material as, e. Type I compounds prolong channel opening only long enough to cause repetitive firing of action potentials (repetitive discharge), whereas type II compounds hold open the channels for such long periods of time that the membrane potential ultimately becomes depolarized to the point at which generation of action potentials is not possible [depolarization-dependent block (Figure 3)]. Excess glutamate release from depolarized presynaptic neurons, together with a diminution in the uptake mechanisms of glia and neurons, results in increases in synaptic glutamate and pathologic stimulation of N-methyl-D-aspartate (NMDA) receptors. |
