An animal’s behavioral state is reflected in the dynamics of population activity and its capacity to process sensory information. Previous studies in mammalian brains have demonstrated a relationship between behavioral states and information processing (Lee et al., 2016, 2019, 2020). However, these studies have been limited to exploring how population dynamics and sensory representation changes in specific cortical areas. Thanks to its transparency at early life stage and the advent of selective plane illumination microscopy, the zebrafish brain is an attractive model that allow for whole brai

The primary somatosensory area of the mammalian cerebral cortex is known to play a key role in tactile sensory processing and touch perception, which may not be restricted to an efficient analysis of the incoming sensory flow. Indeed, the neocortex is thought to be capable of generating predictions about future events based on the context, our past experiences and current motor actions. According to predictive coding theories, sensory perception would rely on the continuous comparison of expected sensory inputs with those actually received, and the error signal generated in case of mismatch be
