| The cerebral cortex is a recurrent network of excitatory and inhibitory cells that even in the absence of any external input generates spontaneous activity. This spontaneous activity is usually organized in rhythmic patterns that go from slow (less than 1 Hz) to fast (40-80 Hz) rhythms. This spontaneous activity propagates across the network. In this talk, the mechanisms that determine different rhythmic patterns will be discussed based on experimental and modelling results. The alteration of some of these control mechanisms will result in a perverted activity as it is the epileptic one. |
