Resumen:
Collective activity of neurons could play an important role in the large-scale integration of brain and there is still no integral formulation of the laws that govern its dynamics. As collective activity responds to evoked stimuli, we study thespatiotemporal properties of visually-evoked neuronal responses using high density surface electrocorticography (ECoG) recordings sampling neuronal activity along an entire hemisphere of the mouse brain. We combine surface and laminar recordings in different cortical areas within and outside the visual system. We found that in time domain, responses evoked by identical visual stimuli vary dramatically between trials and across individuals. Yet, frequency-domain analysis showeda consistent visually evoked synchronous gamma band oscillation (30-50Hz), which is present in all mice and coherent across trials in the early phase (
