Since many processes in the nervous system are not normally seen to exhibit such runaways, there must be some factors opposing the primary instability. One is described briefly, showing that stabilization of a thresholded network is not difficult. The application of these facts to various symptoms ...
Central nervous system (CNS) oxygen toxicity, as manifested by the first electrical discharge (FED) in the electroencephalogram, can occur as convulsions and loss of consciousness. CO(2) potentiates this risk by vasodilation and pH reduction. We suggest that CO(2) can produce CNS oxygen toxicity...

Understanding these thresholds is crucial in studying the functioning of the nervous system and how signals are transmitted in the body. In economics, threshold is used to describe the level at which a particular action or decision becomes necessary or desirable. For example, in the context of ...

As illustrated in Fig. 2, the different separatrix types for different neuron classes define the instantaneous threshold voltages well. As an excitable dynamic system, the neuron defined by equations (2) and (3) must pos- sess at least one stable equilibrium. The stable equilibrium of a ...
The data suggest that the T-type Ca2+ current may play an important role in the processing of information in the nervous system by virtue of its ability to elicit burst firing in neurons. 展开 关键词: Neurobiology Ion Currents Dorsal Root Ganglia Epilepsy Repetitive Firing ...
