#CogNeuro seeks unified theories of behavioral, physiological, and mental states. To this aim, our @NatureNeuro Perspective proposes a new framework centered on #TaskDemands & across-task generalization. https://t.co/EKXhrcJbUC

@jamesgheys1 @ErinBigus @Hyunwoo_Lee5223 Congratulations @jamesgheys1 ! Great to see this work finally published 😀

[SfN Journals @SfNJournals]

#JNeurosciAnnualSpotlight | Azizi, @nachopolti, and @virginie_vw @neurospin discovered that cortical alpha burst activity may represent a state of awareness occurring only in the absence of attention to time. This enables later recall of time duration. https://t.co/UvGdk63kNE

[Thérèse Collins @theresecollins.bsky.social @TCollinsUPCite]

A new Master’s program in #cogsci is born!
Operated jointly by @Sorbonne_Univ_ and @univ_paris_cite, in Paris w/ 100% of classes & internships in English, the cog-SUP program will open in Sept 2024 with its 1st class of students.
Applications open soon!

#JNeurosci: This MEG study from Azizi, @nachopolti, and @virginie_vw @neurospin suggests that brain rhythms called alpha bursts temporally track states of awareness in episodic memory, from which future recollections of elapsed time will be derived.

Happy to see this work finally out! Together with Leila and @virginie_vw we explore the link between alpha brain rhythms and retrospective timing in humans 🧠🕓

@pearlsaldanha @JonRWhitlock @Jingyi_GF Congratulations! 😀

[Ignacio Polti @nachopolti]

Interested in how temporal context modulates #gridcell-like signals in the human entorhinal cortex during sensorimotor timing behavior?

Come by my #SfN22 poster SS6 today to hear how @NauMatt and I studied this together with R. Kaplan, @virginie_vw and @doellerlab | @KISNeuro

[MPI für Kognitions- & Neurowissenschaften @MPI_CBS]

It's very important in sports, and in interpersonal relationships, too - perfect #timing. @NauMatt & @nachopolti together with Christian Doeller @doellerlab demonstrate in an #MRI study that our #brain learns best in connection with constructive #feedback. https://t.co/xTLJ34comI

[Ignacio Polti @nachopolti]

@NauMatt @eLife @doellerlab @virginie_vw Code & data are #openaccess and can be found on @OSFramework: https://t.co/RMItjQ4TjB

New paper @eLife with co-first author @NauMatt!

Hippocampal activity reflects timing behavior & the updating of task-specific yet generalizable sensorimotor representations in real time https://t.co/sMuL41GmGR

🧵 Joint-author thread below!
w/ R.Kaplan @doellerlab @virginie_vw

[Ignacio Polti @nachopolti]

@NauMatt @eLife @doellerlab @virginie_vw Yes! In addition to behavioral feedback, the (anterior) #Hippocampus signaled how strongly TTC estimates converged onto their mean (Tweet 5)

In machine learning terms, its activity appears to reflect “regularization” and “accuracy”

Again, strong differences across regions!
