In a state of sensory deprivation, sensory areas in the brain remain highly active. This activity, once interpreted as irrelevant noise, has been found to exhibit highly
coherent spatiotemporal structures.

To understand the biological meaning of these ongoing activities we are using the
zebrafish larva as the experimental model which enables monitoring the activity of large portions of the nervous system with single-cell resolution in an intact behaving vertebrate.

Our preliminary results suggest that the ongoing spontaneous tectal activity shows a biological relevant structure that may help increase the signal-to-noise ratio for stimulus detection in low-contrast or cluttering backgrounds.
