Segmenting, Connecting, and Recalling Events
Description
**Faculty Candidate - Cognitive Neuroscience**
How do we divide our world into parts? How do we synthesize parts into integrated wholes? I present a model of how our brain segments and connects information in naturalistic stimuli that are structured in space and time. Using a multivariate cross-decoding approach, I identify brain regions that are sensitive to configural arrangements of spatial information during action perception. In the context of narrative comprehension, I show how to decode event boundaries from neural activity, and find that our brains segment events across a hierarchy of timescales, ultimately extracting a modality-invariant situation model that is stably represented in higher-order brain regions. These high-level event boundaries are not only used to integrate events in the present, but also organize the encoding and recall of long-term episodic memories. Finally, I will discuss how we acquire the knowledge about event structure that later enables us to link information in space and time.
