Excited to share our new findings: transcutaneous vagus nerve stimulation leads to increases in locus coeruleus activity, which correlate with changes in salivary alpha amylase in older individuals. #locuscoeruleus www.brainstimjrnl.com/article/S193...

Locus coeruleus fMRI response to transcutaneous auricular vagus nerve stimulation is coupled to changes in salivary alpha amylase
Transcutaneous auricular vagus nerve stimulation (taVNS) has shown promise to non-invasively enhance memory in older adults and those with mild cognitive impairment (MCI) [1,2]. Evidence suggests this...

In life, 3 things are certain: death, taxes, and decision-making variability🧠. Our review tinyurl.com/4dcwafc4 explores how computational models 💻 explain variability, their limits, and recent advances. A thread🧵👇 @redmondoconnell.bsky.social @neuromurphy.bsky.social Mark Bellgrove (not on Bluesky)

Does tVNS elicit replicable effects beyond BOLD responses in the brainstem? Yes, pulsed, but not conventional tVNS leads to robust pupil dilation in our new meta-analysis. Published in Brain Stim w/ @cecivez.bsky.social @akuehnel.bsky.social #neuroskyence 🩺 www.sciencedirect.com/science/arti...
Across 18 studies, the meta-analysis shows moderate evidence against an effect of taVNS on pupil dilationStimulation effects of taVNS on pupil dilation depend on the use of a phasic vs. conventional protocol.

Anne Churchland and Felicia Davatolhagh discuss why we must address the gender gap in neuroscience citations. www.thetransmitter.org/publishing/w...

Women are systematically under-cited in neuroscience. New tools can change that.
An omitted citation in a high-profile paper led us to examine our own practices and to help others adopt tools that promote citation diversity.

Are people back on BlueSky? I hope we can leave Twitter behind while keeping the good scientific community we once had there. We have a new preprint on tVNS-induced pupil dilation. It comes again with a Shiny App to customize the settings. #neuroscience www.biorxiv.org/content/10.1...

Our latest result is out now: phasic and tonic taVNS at rest, under standard params, might both modulate the noradrenergic system in phasic mode only (by proxy of pupil dilation). With the great team @marzecova.bsky.social and Gerhard Jocham at @hhu.bsky.social 🙌 #neuroskyence

Tonic and phasic transcutaneous auricular vagus nerve stimulation (taVNS) both evoke rapid and transient pupil dilation

My article, "We know what attention is!" is out in @TrendsCognSci . it argues that our experimental methodology commits us to a simple functional conception of attention. In that sense, we agree on and know what attention is. I will thread about it later. authors.elsevier.com/a/1iGCs4sIRv...

Vagal signals are classically seen as inhibitory but there is lots of evidence suggesting they are way more adaptive than that. @nbkroemer.bsky.social and I packed them into an easily digestible TiCS review for you to feast on 🔥 50 day free access, and a little appetizer 👇 🧠🟦 tinyurl.com/bdh279jv

First paper share on BlueSky! Our new result (w Anna Marzecova & Gerhard Jocham): phasic and tonic taVNS at rest, under standard params, might both modulate the LC-NE system in phasic mode only (here: by proxy of pupil dilation) - possibly important for use in tasks. www.biorxiv.org/content/10.1...

Both tonic and phasic taVNS protocols induce rapid and transient pupil responses. Surprising how similar the responses actually are in light of previous studies. Great work by Skora, Marzecova, & Jocham (not on bsky yet). #neuroscience #psychology 🩺 www.biorxiv.org/content/10.1...
Similar changes in pupil dilation in the phasic and tonic
