Topic: event segmentation

Our experience of the world is a continuous stream of events, things occurring at a particular time and place. How this flow of experience is parsed and organized impacts our perception and memory of such events, yet the neural mechanisms underlying this process are largely unknown. The lateral entorhinal cortex may play a key role due its convergence of multisensory inputs, its encoding of events and their temporal relationships, and its connections with the hippocampal memory system. Here, we simultaneously recorded hundreds to thousands of neurons from lateral entorhinal cortex (LEC), media

Catecholamines play a crucial role in updating mental representations in a world where constant exposure to new information requires continuous adjustments in our actions. To examine how the catecholaminergic system may influence how we structure the continuous stream of information around us into manageable parts, this study makes use of the theory of event segmentation. Building on previous findings, we propose that methylphenidate’s effect on event segmentation behavior depends on learning/prior knowledge and stimulus novelty.
