Our new paper https://t.co/JEFw6Efy5w shows that the mental models subjects bring into a two-stage task can drastically change their behavior. This thread is teaser of this work lead by @carolfehersilva now out in @NatureHumBehav #neuroeconomics @econ_uzh

We are eager to put this to work (EEG-informed laminar and subcortical imaging). Interested in this type of measurements? We are about to announce several postdoc positions to work on an @ERC_Research project on learning and decision making. Stay tuned 2/2

Our bespoke head coil for simultaneous EEG-fMRI in 7T by @Shajan_G w/ new EEG cap design by @Brain_Products. Open design concept allowing EEG amps next to subject’s head. Negligible loss in B1+ and fantastic EEG signal recovery (comparable, if not better than our 3T setup) 1/2 https://t.co/pT12Qo6BaK

Many congrats to all our staff promoted this year Research Associate Chaona Chen & Katarzyna Jaworska Research Fellow (Grade 8) Gemma Learmonth & Greg Weir Lecturer (Grade 8) Chiara Horlin Senior Lecturer Heather Cleland Woods Prof Rachael Jack & Prof Marios Philiastides https://t.co/GeeXKJm2un

Big congratulations everyone! https://t.co/1TKeEipdQn

Some optimism to start the day - with labs starting to reopen, we're recruiting for a new Wellcome-funded postdoc to join us @EP_UCL @WCHN_UCL later this year. Advert and link to apply is here (closes 29th July): https://t.co/tEauoxdonU Please RT!

Check out our new preprint on #serotonin and #pupil #arousal resulting form an in house #collaboration! Cazettes, Reato, Morais, @arenart73 & @zmainen https://t.co/0bfsoD6MEf

Opponent intracerebral signals for reward and punishment prediction errors in humans https://t.co/POdc32BURy #biorxiv_neursci

“Opponent intra-cerebral signals for reward and punishment prediction errors in humans” Wonderful preprint by @maelle_gueguen and colleagues where they investigate the intracranial correlates of punishment avoidance vs. reward seeking learning. Thread 👇 https://t.co/fg3tL5lu3r

How sensory evidence is transformed into motor output is not fully understood. Here, the authors use stereoEEG recordings during a rule-switching task to reveal network dynamics of decision making. @MarijeterWal

Ever wondered why the decision between caramel and chocolate could be trickier than you think? Get your tickets now and tune in on the 19th. https://t.co/Kx2UoxwpUx

This 👇 is happening, thanks to @The_MRC support. I am looking for postdocs and RA to join the group (Nox Lab) ~Jan 2021, when I will be back from maternity leave. Get in touch if you are interested in pain and computational neuroimaging! https://t.co/bKIiR2Spgc https://t.co/cdFqfxf0we

Excited to share our preprint “Ramping activity in midbrain dopamine neurons signifies the use of a cognitive map” led by grad student @Akash_Guru_. Ramps fade when sensory cues are available but persist when an internal model of goal progress is required. https://t.co/oa3oSDEjXl https://t.co/ECPaK6P2xo

Pupil diameter encodes the idiosyncratic, cognitive complexity of belief updating https://t.co/O5ZZlhjIoQ #biorxiv_neursci

New preprint! We use a new task to show that pupil dynamics reflect computations required to update beliefs, which we dissociate from low-level stimulus properties (switches). These effects were also modulated by idiosyncratic subject beliefs. Details in thread. 1/8 https://t.co/0IbYDRUYco

Cortical neurons can oscillate at 10 Hz on their own. We analyze laminar LFPs to show that alpha pacemakers are located in deep layers (IG) in V2/V4 but in superficial (SG) layers in IT (arrows understood in the sense of Granger causality). https://t.co/ld1I2SbDt2 https://t.co/8LKqQmBhRm
