Limit cycle behavior with two neurons
NettetWe prove that generic noninhibitory systems must exhibit a periodic behavior, a finite number of limit cycles, and two (at most) binary codes defined by the periodic neuron … Nettet8. sep. 2014 · This is to be contrasted with the behavior of models with a saddle-node-onto-limit cycle behavior. As discussed above, the amplitude of the response of type I …

Nettetentrain the SCN to extreme T-cycles (i.e., 22 and 26 h) if a higher proportion of neurons are responsive to the zeitgeber (Gu et al., 2012). Here, we mathemati-cally explored the impact of changing the proportion of neurons that receive the external stimulus on limit cycle oscillator behavior in an attempt to resolve dis- NettetSo after perturbation we obtain two additional (smal) limit cycles. So we have 4 limit cycles with (3,1) distribution It is unknown whether there is a quadratic system with …
Nettet6. mai 2011 · Here we describe noisy limit cycles and quasi-cycles, two related mechanisms underlying emergent oscillations in neuronal networks whose individual components, stochastic spiking neurons, do not themselves oscillate. Nettet11. des. 2024 · 3.2 The Firing Rate Function. Since our neuron model is a map, the period P of its limit cycle lies in \(\mathbb{N}\) for all positive suprathreshold drives ς. Therefore, the spiking rate function is staircase-like, with points of discontinuity whenever \(P\to P+1\).
Nettet1. feb. 2014 · If all neurons receive external input, the SCN shows limit cycle behavior in all conditions. If all neurons do not receive light input, we found that the entrainment range of the SCN was...
