Preprint alert!!! We recorded directly from the human ventral tegmental area (VTA), the principal source of cortical dopaminergic innervation, while patients performed an instrumental learning task. ๐งต๐

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought.

A birthday is a good time to reflect! To mark SPM @ 30, this month's issue of Cerebral Cortex features deeply insightful commentaries on neuroimaging analysis from Ed Bullmore, Peter Bandettini, Peter Fox, Pedro Valdes-Sosa, Klaas Enno Stephan, Viktor Jirsa, et al [1/2] academic.oup.com/cercor/issue
Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric โp-factor.โ But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... ๐งต Thread with our reflections on the matter ๐
Spoke at my first #OHBM in Brisbane ๐ฆ๐บ and received a Merit Abstract Award. We conducted the first human study recording LFPs from the VTA during reward learning. Signals reflected reward outcomes and expected value. Grateful to @vlitvak.bsky.social, mentors and our team. Manuscript ๐
