Reposting videos from Twitter: #3 an analogy between the cortex and a boat. The default mode network is analogous to the keel, hiding under the waterline and serving as a counterweight to the forces acting on the sail.

Thinking about physical space, the cortical surface and brain function. In cartography, different flat projections of the globe are used for different functional purposes (e.g., navigation, measurement, radar) each projection transforms space in different ways to achieve that purpose.

"Importantly we looked at how many people you would need to show the relations in the best tasks for capturing a specific trait. Our estimates suggest hundreds (not thousands) of people would be needed to show the brain-trait relationship seen in the whole sample."
November 15, 2024 at 10:37 AM
"These relations were clear for #gradients 3 (task positive-task negative) and 2 (vision-motor). Tasks with a strong response for one trait were different to those for other traits. This suggests there is likely no -one-size-fits-all situation for all brain-trait associations"
November 15, 2024 at 10:37 AM
"We examined if location of any of the tasks in the state-space varied with traits using Linear Mixed Models in R. We found little evidence that traits uniformly impact on brain activity in all tasks. Instead brain-trait association were often stronger in some tasks than others 👇"
November 15, 2024 at 10:37 AM
To this end we took the task data from the Human Connectome Project and examined how brain activity in each situation vary with the Big-5 Personality traits. We built a 3d state-space using the first three #gradients from the work by Daniel Margulies and projected task data into it 👇
