Oscillating population models

Slow oscillating population activity in developing cortical networks: models and experimental results.

During early development neuronal networks express slow oscillating synchronized activity. The activity can be driven by several, not necessarily mutually exclusive, mechanisms. Each mechanism might have distinctive consequences for the phenomenology, formation, or sustainment of the early activity pattern. Here we study the emergence of the oscillatory activity in three computational models an...

Forced Oscillations in Self-Oscillating Surface Reaction Models

1 Introduction Harmonic resonance, subharmonic and superharmonic entrainment, quasiperiodic and chaotic behavior are well known to occur in nonlinear self-oscillating systems which are subject to periodic forcing. Harmonic resonance occurs if the periodic forcing signal has a frequency very similar to the one of the undisturbed system and results in an amplification of the oscillations.

Oscillating wildly

ome cells can induce the production of their own protective blanket. The signal comes from active neurons in the central nervous system (CNS), and triggers the differentiation of oligodendrocyte precursor cells (OPCs)—thus yielding the cells that cover the neurons with a protective sheath of myelin. Now, Beth Stevens, Douglas Fields, and colleagues (National Institutes of Health, Bethesda, MD) ...
