New preprint: "Monosynaptic connections link functionally similar regions in human cortex." We use electrical stimulation + fMRI in epilepsy patients to map whole-brain monosynaptic connectivity at 42 cortical sites. doi.org/10.64898/2026.… 1/n

@Norcal_Neuro @dyamins Highly interesting! This seems broadly consistent with what we saw in human iEEG data: doi.org/10.1101/2023.0…

1/ New preprint with @dyamins + team! Ventral visual representations within areas evolve over the course of the response along the same hierarchical complexity axis that distinguishes the visual areas, potentially driven by local recurrence. biorxiv.org/content/10.648…

Es-fMRI offers a scalable platform for a tracer-grade human connectome, with implications for human cognitive neuroscience, patient-specific neuromodulation, and biologically grounded computational models of cognition. More to come. 14/n

Many thanks to @AlanBushPhD, Atsushi Takahashi, @ndsisterson, A. Walton, @samhutch511, John Yee, John Kirsch, @ev_fedorenko, @Nancy_Kanwisher, Bob Desimone, @RMarkRichardson, and other amazing coauthors and teammates. And, our patients, above all. 13/n

I still get chills Meet Mike *30+ years severe depression *first hospitalized @ 13y *20 meds *3 rounds of ECT *2 near-fatal suicide attempts Mike felt joy for the first time in decades after we turned on his new brain pacemaker or PACE see paper, thread doi.org/10.31234/osf.i…

Excited to share our latest story! We found disentangled memory representations in the hippocampus that generalized across time and environments, despite the seemingly random drift and remapping of single cells. This code enabled the transfer of prior knowledge to solve new tasks

I’ll present preliminary data of human eStim-fMRI and same-individual characterizations of cognitive functions (w/ @ev_fedorenko and @Nancy_Kanwisher). Such data will enable us to go well beyond existing work in relating anatomy to function. Please drop by and chat! (2/2)

My #SfN24 poster is on Tuesday morning (303.11, T2). We (w/ @RMarkRichardson @brainmodlab ) devoloped a safe, high-SNR eStim-fMRI protocol for mapping close-to-ground-truth anatomical connectivity of the human brain in epilepsy patients, taking <5 min per stim site. (1/2)
