NONLINEAR DYNAMICS IN NEURAL FUNCTION
Neurons display a wide variety of different non-linerar dynamics,
such as action potential firing, sub-threshold oscillations
and the non-linear integration of synaptic inputs. We have used
in-vitro patch clamp recordings in slices of the mouse visual cortex
and biophysical simulations to investigate some of these phenomena.
In particular, we investigated the irregularity of spike trains in
pyramidal neurons and interneurons, the effect of the neuromodulator
acetylcholine on the spike phase-reset curves of neurons and the
interaction of sub-threshold oscillations with inhibitory synaptic
potentials. A framework derived from dynamical-systems theory
unifying these phenomena is presented.
