Object dimensions underlying food representations in visual cortex

The paper identifies distinct computational constraints in lateral and ventral OTC for food representations, showing lateral regions prioritize action-related properties and ventral regions prioritize visual features.

Noisy models of the ventral stream reveal the impact of recurrence and learned representations on information processing timescales

The paper investigates how network architecture influences representation timescales in a noisy, recurrent model of the ventral visual stream, showing that timescales are set by architecture rather than training.

Pre-stimulus pupil-linked arousal enhances initial stimulus availability and accelerates decay in iconic memory.

The paper shows that pre-stimulus pupil dilation, reflecting arousal, increases initial stimulus availability in iconic memory but accelerates its decay, without affecting memory transfer or confidence.
