New from our @cognizelab.bsky.social in Advanced Science:
Beneath the Big Five, personality consistently organises into two dimensions, each with distinct brain signatures.
Amazing work by postdoc @kaixiangzhuang.bsky.social and thanks to all our collaborators! doi.org/10.1002/advs...
Thanks a lot Rod!

Our findings reveal that the brain does not just detect "novel or familiar", it represents spatial novelty as continuous gradients, which may be a fundamental organisational principle for spatial cognition 🌍🧭 (and potentially other structured knowledge - to be continued…)
Figure 4: Hippocampal-cortical coupling reflects shared novelty preferences
Using rest-fMRI, we found that hippocampal voxels and cortical vertices with matching novelty preferences showed STRONGER intrinsic connectivity.
This suggests the gradients are functionally coupled!
Figure 3: Two streams of cortical processing for spatial novelty
🔴 Visual + frontoparietal networks → responded to NOVELTY
🔵 Default mode + motor + ventral attention → responded to FAMILIARITY
Importantly, we found a centre-surround gradient in posterior medial cortex!
Figure 2: A novelty-to-familiarity gradient along the hippocampal long axis
🔴 Posterior hippocampus → preferred NOVEL spaces
🔵 Anterior hippocampus → preferred FAMILIAR spaces
Though this division wasn't binary: we found a smooth, continuous gradient!
Figure 1: How we quantified spatial novelty during free exploration
During 7T fMRI, participants navigated a VR arena collecting objects while we tracked their every move. We divided the arena into sectors and calculated novelty based on visit frequency + time between visits.
🧠 New paper alert (the 1st one from our new lab)!

How do our brains distinguish novel from familiar places as we explore our environments, e.g., a new city?
