Spike response function
WebJul 3, 2024 · The effector response elicited is most simply categorized as “broadly T H 1 (T helper cell 1),” with CD4 responses somewhat dominant over CD8 and epitopes within spike antigen often at the top of a hierarchy of antigens throughout the proteome . Details of this antigen hierarchy seem to differ somewhat with disease severity.

The damage is apparently caused by effects on the mitochondria (energy producing organelles) in the cells – they change their shape and have reduced function.
The spike response model (SRM) is a spiking neuron model in which spikes are generated by either a deterministic or a stochastic threshold process. In the SRM, the membrane voltage V is described as a linear sum of the postsynaptic potentials (PSPs) caused by spike arrivals to which the effects of … See more In the SRM, at each moment in time t, a spike can be generated stochastically with instantaneous stochastic intensity or 'escape function' $${\displaystyle \rho (t)=f(V(t)-\vartheta (t))}$$ See more The Spike Response Model has been introduced in a series of papers between 1991 and 2000.
