PROSPETTIVE TEORICHE E CLINICHE SULLA NATURA RITMICA DELLA PERCEZIONE VISIVA

Visual perception is characterized by the ability to form meaningful objects from the continuous stream of incoming information. While temporal integration processes enable the formation of coherent percepts over time, temporal segregation is critical to segment incoming visual information to unveil changes in the environment. In the last decades, a substantial number of studies has suggested that brain oscillations might provide a neural substrate and a perceptual frame for visual temporal processing. In this paper, we present experimental evidence in favor and against this link, discussing how neuromodulatory techniques such as electrical current stimulation and sensory entrainment can be employed to investigate the functional role of neural oscillations in defining conscious perception both in neurotypical and clinical populations.
