the phase-space dynamics of systems of spiking neurons
... This thesis investigates the dynamics of systems of neurons in the brain. It considers two questions: (1) Are there coherent spatiotemporal structures in the dynamics of neuronal systems that can denote discrete computational states, and (2) If such structures exist, what restrictions do the dynamic ...
