really nice and well done meta-analyses and review here...highly recommended!

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

We are still accepting applications for a tenure track position in cognitive and neural systems in the Psychology Department at University of Arizona. Please repost:

Naturalistic movements enrich episodic memories but not their spatiotemporal structure It remains unclear how episodic memories, our memories for past events, are generated from the rich sensory details encompassing everyday experience. …

how important are space and time to memory? the surprising result from a new paper with graduate student Sameer Sabharwal-Siddiqi is that several measures of space and time show no correlation with the richness of episodic memories! check it out:

Newly trained navigation and verbal memory skills in humans elicit changes in task-related networks but not brain structure Learning new navigation or memory skills engages flexible brain network dynamics without altering gray matter, white matter, or hippocampal structure.

what happens when you spend two weeks learning new navigation or memory skills? as shown in our recent paper below, brain network connectivity changes but not hippocampal or other brain volumes! special thanks to collaborators Li Zheng and Steve Weisberg

This is truly amazing. 85% accurate test in 45 minutes. The work was funded by the National Cancer Institute of the National Institutes of Health. Good thinking on the part of Trump/Musk to cut its funding. Make Cancer Great Again.

We showed we could decode one city from another using hippocampal multivariate patterns. We dealt with the visual confounds that Steve mentioned by having people recall distances from the locations in different environments.

Amazing opportunity to be a lab manager in @sarahsolomon.bsky.social's new lab!!

Thank you Benjamin for a fun conversation. Chance to learn about science...and more...from our discussion!

We're looking for a new postdoc to join my lab group! Please help spread the word. Our project is collaborative study with the Washington State Twin Registry (WSTR) and affords incredible research opportunities related to the behavior genetic study of social relationships and health. Details in link

We have filled two positions but one is still open. Please apply to the position ending in 305– it’s a silly HR thing. Feel free to email me directly for more info.

My lab is recruiting new members for an NIH-funded project to uncover neural mechanisms of motivation and its regulation w fMRI neurofeedback and innovative multivariate modeling.  Please share! Full postings:

I really liked this as well!

Impoverished details with preserved gist in remote and recent spatial memory following hippocampal a... Cognitive Map Theory predicts that the hippocampus (HPC) plays a specialized, time-invariant role in supporting allocentric spatial memory, while Stan…

Does the hippocampus play a time-limited or perpetual role in spatial memory?

In naturalistic tasks, the hippocampus is NOT necessary for gross representations of large-scale environments. But it plays a long-lasting role in memory for local layouts and details.

Memory retrieval is believed to be accompanied by a reactivation (reinstatement) of the neuronal populations that were active when the event was initially experienced (for review, see [Rugg et al., 20...

I wrote a j-club commentary on a recent article published in #Jneurosci by @neurosteel.bsky.social et al. I discuss the phenomenon of retrieval-related 'anterior shift' and I highlight the implications that this work has on studies examining neural reinstatement.

Very pleased to announce our recent paper on aging and spatial memory in PNAS with research scientist Dr. Li Zheng! We find both age-related and performance-related heterogeneity that contribute to older adults having, on average, worse spatial memory. Check it out! www.pnas.org/doi/10.1073/...

Dissociative effects of age on neural differentiation at the category and item level Increasing age is associated with age-related neural dedifferentiation, a reduction in the selectivity of neural representations, which has been proposed to contribute to cognitive decline in older ag...

New paper in #Jneurosci !⭐
doi.org/10.1523/JNEU...

Prior work suggests that age-related reductions in neural selectivity are restricted to the scene-responsive cortex. We show that age effects for other visual categories are observed when selectivity is measured at the level of individual stimuli.
