Subcortical correlates of consciousness with human single neuron recordings Subcortical brain structures contain neurons encoding subjective reports of stimulus detection in human participants, suggesting a role for conscious perception.

New “version of record” in @elife.bsky.social! ‬

We recorded neurons in the thalamus and subthalamic nucleus of humans and found both sensory- and perception-selective neurons with two distinct latencies!

It's been a while since our last laminar MEG paper, but we're back! This time we push beyond deep versus superficial distinctions and go whole hog. Check it out- lots more exciting stuff to come! 🧠📈

My laboratory at Université Laval in Québec City, Canada, is looking for a postdoc to study how neuromodulatory systems impact cortical processing during foraging behavior. This fully-funded position offers a collaborative environment in a great city. More info👇

We are having an amazing time learning about the brain circuitry at the Canadian Association for Neuroscience meeting in Toronto. Not a lot of human brain neuroimaging or pain mechanisms, but hey, that can change!

"These findings challenge the traditional brain-centric view of reward processing, supporting a more unified and integrated model in which gut-derived and vagus-mediated interoceptive signals are pivotal in intrinsically shaping motivation and reinforcement."

Looking forward to #VSS2025! On the first day, @dotproduct.bsky.social sky.social will be presenting a poster on how predictions embedded in alpha oscillations modulate perception of noisy stimuli. Come one, come all! Poster 16.322, Friday 3-5pm, Banyan Breezeway. #neuroskyence #visionscience

When you successfully anticipate future events, what happens to your ability to encode the present? 🤔

Successful prediction increases the likelihood of successful encoding. We speculate about how switching between distinct encoding & prediction states can produce this effect.

Cognitive behavioral therapy skills via a smartphone app for subthreshold depression among adults in the community: the RESiLIENT randomized controlled trial - Nature Medicine A trial that used a master randomized design found that the skills commonly found in smartphone-based cognitive behavioral therapy, when tested alone or in combination with behavioral activation, were...

Published today in Nature Medicine. In one of the world’s largest RCTs of its kind (n=3,936), a smartphone app teaching 5 key cognitive-behavioral therapy skills improved subthreshold depression—and the effects lasted 6 months.
