My husband requested a circuit board design for this t-shirt, in green, of course. I didn’t have quite enough of the main fabric left to cut out the front and back in whole pieces. There was a big chunk missing at the shoulder. So I asked my husband if circuits ever had a reason for two of them to be joined together, so I could fill in the space, and he said sure. When circuit boards are fabricated, the machines make a whole panel of them at a time and they’re connected together with lines of perforation, called mouse bites, so they can later be snapped apart into separate pieces. So that’s how I filled in the gaps at the corners with scrap fabric to make them look intentional.

Mostly 100% cotton jersey, cotton and polyester thread, gold acrylic paint

How are events segmented and organized in time? And how might this impact our perception and memory?

Check out our work here on how neural trajectories in the lateral entorhinal cortex inherently drift over time, but abruptly shift at event boundaries to discretize a continuous experience.

bioRxiv · Event structure sculpts neural population dynamics in the lateral entorhinal cortexOur experience of the world is a continuous stream of events which must be segmented and organized simultaneously at multiple timescales. The neural mechanisms underlying this process remain unknown. Here, we simultaneously recorded many hundreds of neurons in the lateral entorhinal cortex (LEC) of freely behaving rats as we manipulated event structure at multiple timescales. During foraging as well as during sleep, population activity drifted continuously and unidirectionally along a one-dimensional manifold. Boundaries between events were associated with discrete shifts in state space, suggesting that LEC dynamics directly reflect event segmentation. During tasks with a recurring temporal structure, activity traveled additionally in directions orthogonal to the flow of drift, enabling the LEC population to multiplex event information across different timescales. Taken together, these results identify a hierarchically organized neural coding scheme for segmenting and organizing events in time. ### Competing Interest Statement The authors have declared no competing interest.
