QQ11: RSC is using the HPC spatial code for good! We observed retrosplenial populations encode task structure when behaviourally relevant cues were present in a hippocampal-dependent spatial task.

Poster QQ9: Theta sweeps can track moving bait and go backwards!
In our poster, we describe situations in which the stereotypic left-right alternating theta sweep pattern is modulated to cover behaviorally relevant space @azvollan.bsky.social

QQ7: How do MEC ultraslow dynamics vary across behavioral states. In free foraging, population dynamics organize in ultraslow sequences while in NREM sleep they present as synchronous oscillations.

QQ5: What is the developmental timeline of the low-dimensional manifolds of the entorhinal cortex? Rings and tori organize at P9-P10 before major sensory-motor milestones, coinciding with other major shifts in MEC cortical dynamics. @me

QQ4: QQ4: We study population dynamics across the spatial navigation circuit as a rat moves between 4 rooms. With 4 NPX probes in CA, MEC/PaS, SUB, and dPreSUB, we see how maps switch at a fine timescale and track when each region settles into the correct representation. @jocarpenter.bsky.social

QQ3: We observe hexagonal grid cells even in environments with elevation changes! The hexagonal pattern is cleaner on the surface of a ramp and on a dome seen from above, and more distorted on a cone seen from above.

QQ2: Where are the grid cells and if so, how many? We find that grid cells form a discrete "hot spot" segregated from other functional cell types in the superficial layers of MEC and PaS. @martipof.bsky.social
