🚨 🧠
We have a new preprint out where we studied which brain networks are engaged during mental imagery and self-generated thought.

We used a precision fMRI approach along with multidimensional experience sampling (mDES) to get trialwise self-reports from each participant about what they imagined.

New preprint!!!

We can reliably detect brain changes in individuals in just a year by collecting several rapid 1-minute T1s at each time point - i.e. "cluster scanning". We discovered large individual differences, even in healthy adults

As if there wasn’t enough to worry about…

It turns out the Salience (SAL) and Parietal Memory Networks (PMN) are the same thing!

😩😩😩

🧵

These findings not only show an interesting functional dissociation along the hipp. long axis, but also highlight the value of network-driven, domain-agnostic explorations of hippocampal function for identifying surprising findings, like the Posterior-SAL hipp. sensitivity to transient salience.

In a surprising contrast, the Posterior-SAL hipp. region was not primarily sensitive to scene construction, instead showing activity in response to salient stimuli (A & B below) and task transitions (C & D below), despite these tasks having no obvious declarative or associative memory demands.

Activity within hipp. regions closely resembled that of their partner cerebral network.

The Anterior-DN showed increased activity when participants were asked to imagine their future, and in particular was driven by the process of scene construction (see work from @laurendinicola.bsky.social).

In 20 extensively scanned participants (Discovery n = 11, Replication n = 9), we segmented the hippocampus based on differential functional connectivity to two cerebral networks, identifying distinct Anterior-DN and Posterior-SAL hippocampal regions (following the lead of Zheng et al. 2021).

We revisited the functional specialization of the human hippocampal long axis across two independent datasets, with some surprising results.

New paper out in Nature Neuro, wherein we ask:

How do perceptual and mnemonic brain networks share information?
