3) @dianacperez.bsky.social is presenting TUESDAY AM at LPB028
Diana used precision datasets of younger and older adults to individual brain network maps
▶️ she shows that variability increases across the lifespan, suggesting new models for the development of individual differences

1) @zachladwig.bsky.social will be available on SATURDAY PM at poster CC14
He’ll show his work using precision fMRI to identify new common network motifs in the PFC and investigate how network borders support executive function.

This approach has uncovered key 🧠 network insights into, e.g.:
• distributed & parallel association networks
• prefrontal specialization
• motor map interruptions (from @gordonneuro.bsky.social 👇)
• subcortical–cortical links
• network evolution & development

In the face of these individual differences, how can we find common principles in 🧠 organization across people 👨👨👧?
We map out a strategy using a series of relative ‘zone’-based markers.

This is because brain network features occur in different locations across people 🧑🧔🧑🦱🧑🦰🧓👱♀️
We review recent work highlighting the scope & characteristics of individual variability in brain network organization.

(8) - Cognitive control tasks activated a set of regions, but rather than matching a single network, these sat near the borders of individual control networks (FP, DAN, CO).
This echoes recent work by @moatazassem.bsky.social and suggests borders could be sites of cross-network communication

(7) Task activations matched network boundaries even in idiosyncratic locations! Like a piece of the language network in mid-LPFC. These cases provided clear examples of functional interdigitation and how group maps overestimate overlap/blurring of distinct regions

(6) These individual-specific activations corresponded better to individual-specific brain networks versus group average estimates.
** Note: this individual advantage was generally true, but was larger in the LPFC than in the rest of the brain!

In several ways we found that the answer was yes.
(5) Replicating prior work by @rodbraga.bsky.social @laurendinicola.bsky.social @jingnandu.bsky.social we found language, theory of mind, and episodic projection contrasts preferentially engaged LPFC regions of the LANG, DN-A, & DN-B

(4) The rostral CO region was a special high-density-zone relative to other regions of the brain (confirmed with spin test). All 7 association networks frequently appeared near this location.

Most neuroimaging studies have identified either:
(1) relatively little functional differentiation in the LPFC, supporting the idea that a large chunk of the LPFC may be flexible or
(2) that its function changes in a slow, continuous, gradient-like fashion.

The lateral prefrontal cortex 🧠— which we think of as critical for goal driven behavior + is a target for psychiatric treatments— is fundamentally different in individuals relative to the group averages we’ve often studied.
