Distance Mapping and Variable-Specific Geometry of Goal-Relevant Frames in the Retrosplenial Cortex
Goal-directed navigation requires animals to continuously update their position relative to an unmarked goal. Here, we recorded retrosplenial cortex (RSC) activity in freely moving rats during goal-directed navigation and random foraging. We found that RSC neurons encoded the Euclidean distance to the goal, and that this distance representation was selectively biased toward the goal during navigation.
Mesoscopic cortical activities associated with pupil-linked perceptions inferred via explainable machine learning
Pupil dilation reflects arousal-related neural processes and is closely linked to sensory perception, attention, and cognitive state, but the mesoscopic cortical dynamics that accompany stimulus-evoked dilation remain unclear. Here, we combined simultaneous pupillometry and wide-field Ca2+imaging in mice with explainable machine learning to identify cortical activity patterns predictive of pupil dilation. Cortical activity was recorded during hindpaw somatosensory stimulation, visual pattern...
