Description	A large scale simulation of the cat cortex was performed using a cluster supercomputer. The model was assembled from a quarter-million single neuron models and the transmission of spikes between neurons was simulated. The V1 area of the cat visual cortex was stimulated with direct current to explore the propagation of signals from the visual cortex. A low frequency (5Hz) activity has been detection upon stimulation. The numerical properties of the simulation were investigated. A reverse estimation of the connectivity matrix and signal propagation delays have shown that the simulation was numerically sound and stable.

(en) Byla zpracována rozsáhlá simulace kočičího kortexu na clusterovém superpočítači. Model kočičího kortexu byl sestaven ze čvrt milionu jednotlivých modelů neuronů a byl simulován přenos akčních potenciálů mezi neurony. Oblast vizuálního kortexu V1 byla stimulována stejnosměrným proudem, aby bylo možné prozkoumat vlastnosti propagace signálu modelem. Během této simulace byla detekována nízkofrekvenční aktivita na frekvenci přibližně 5Hz. Zpětné odvození matice propojení kortikálních oblastí z výsledků simulace a odhad signálového zpoždění ukázaly, že simulace byla numericky stabilní a správně reflektovala strukturu modelu. (cs)
