Abstract

fetched live from OpenAlex

In this paper, we investigate the dynamic behavior of a system oftwo coupled Hindmarsh-Rose (HR) neurons, based on bifurcationanalysis of its fast subsystem. The individual HR neuron has chaoticbehavior, but they can become regularized when coupled throughsynaptic coupling or joint electrical-synaptic coupling. Throughnumerical methods we first investigate the bifurcation structure of its fastsubsystem. We show that the emerging of periodic patterns ofneurons is related to topological changes of its underlyingbifurcations. The Lyaponov exponent calculations further reveal thepathway from chaotic bursting behavior to regular bursting of HRneurons. Finally, we include both electrical and synaptic couplingin the system, and numerically calculate the time dynamics. Eventhough electrical couplings (or gap junctions) usually does notregularize chaotic trajectories, but joint coupling has been moreeffective than synaptic coupling alone in producing stable rhythms.The main contribution of this paper is that we provide amathematical description for transitions of neuron dynamics fromchaotic trajectories to regular bursting when synaptic andelectrical-synaptic coupling strengthens, using bifurcationanalysis.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
