@i_am_shri_ @TrikBek @fMRI_today @ArziAnat @PedroMediano @ETagliazucchi @javiergcas Thank you Sri!

@SamikaKumar_ @TrikBek @fMRI_today @ArziAnat @PedroMediano @ETagliazucchi @javiergcas Congrats for the nice work :)

Brain network dynamics in transitions of consciousness reorganize according to task engagement Excited to share my first PhD work with @TrikBek @fMRI_today @ArziAnat @PedroMediano @ETagliazucchi @javiergcas Corinne Bareham and Isabel Fernandez biorxiv.org/content/10.110… 1/7

This work shows the brain’s capacity for flexible reorganization during decreasing alertness. Understanding how alertness fluctuations and cognitive processing jointly modulate brain networks is needed to develop an integrated framework of consciousness and cognition. 7/7

3) When people became drowsy, active task engagement was associated with increased long-range frontoparietal synchronization, but passive listening was mainly associated with increased parietal synchronization. 6/7

@TrikBek @CambPsych @CamBrainCNS @CamNeuro @fMRI_today Really grateful to @TrikBek for constant support and mentorship, and thank you @CamBrainCNS for the great experience!

I got an evening better pic of @SamikaKumar_ giving her wonderful talk about brain dynamics during film watching when awake and drowsy 😴 @CambPsych @CamBrainCNS @CamNeuro @fMRI_today

Short of sleep these days? 💤 We got you 😉 Join us 7pm on 11 April for our next Neurotalks, this time on Sleep and Consciousness! More on our three wonderful speakers, @SamikaKumar_ from @CambPsych, @Neurocool from @MRC_LMB, and @TomMcClelland1 from @CambridgeHPS, below ⬇️🧵

Our open-source #python toolbox for automated sleep staging has now been published in #eLife! And it doesn't stop to sleep staging: events detection, artifact rejection, spectral analyses, phase-amplitude coupling, and more! @sleepdiplomat #sleep elifesciences.org/articles/70092

Weird, but true: the fMRI-BOLD signal in human V1 reflects arousal and behavioral performance on the timescale of individual trials. Happy to finally share our paper! Work with Minyoung Ryoo, @zviroth, @SagharMirbaghe1, @djheeger, and @elimerriam.

"Ketamine and sleep modulate neural complexity dynamics in cats" New colab paper led by @claubotica with Castro-Zaballa @PedroMediano @DanielBor and @ptortero in a collaboration between us at @CambPsych and the Lab of Sleep Neurobiology @Udelaruy. biorxiv.org/content/10.110… 1/n
