Dissociable effects of curiosity and hedonic valence on reinforcement learning
Curiosity and exploration support learning and adaptive decision-making in uncertain environments. While these processes are sensitive to motivational context, it remains unclear how outcome valence s...
Why do we go downstairs when we hear a scary noise at night?
New #preprint by postdoc Kati Rothenhoefer shows how novelty seeking & explore-exploit decision making in #macaques resolves curiosity about whether choices will lead to appetitive or aversive outcomes.

GitHub - Julie-Fabre/bombcell: Automated quality control, curation and neuron classification of spike-sorted electrophysiology data
Automated quality control, curation and neuron classification of spike-sorted electrophysiology data - Julie-Fabre/bombcell
π We are excited to share that bombcell is now available in Python! π Automatically sort your units into good/MUA/noise/non-somatic using quality metrics and interpretable & adjustable classification thresholds.
pip install and play around with our toy dataset:

Well whether or not "they have to do it", is still a question, but I would say blinking is a convenient way to break up incoming information.
Next time you give a lecture or a talk, take note of when the audience blinks relative to your speech cadence and information you are sharing

The idea of blinking and editing are linked comes from the first link - "In the Blink of an Eye: A Perspective on Film Editing" by Walter Murch
"...And that blink will occur where a cut could have happened, ... Not a frame earlier or later." (pg 36)

In a past life I did film production and editing and we knew to make edits around content - we would see blinks in the audience with cut scenes as if they were chunking information
I remember reading this back in the day which helped me a lot with editing

Dynamic basal ganglia output signals license and suppress forelimb movements - Nature
Basal ganglia output neurons fire dynamically in bidirectional and movement-specific patterns to license forelimb movements.
Forelimb movement control at the basal ganglia - brainstem interface!
Happy to finally share this work from me and @harsh-kanodia.bsky.social with Silvia Arber!

Grab a drink, sit down, and let me walk you through the moment-by-moment process of how information loops through basal ganglia circuits during a decision.

Having learned from Carl both as an undergraduate and graduate student, I continuallyΒ go back to my notes and the topics studied in his course to help me think about concepts in cognitive neuroscience.
Thank you, Carl

Super proud of this work and as I finish up my #PhD studies I am actively looking for a #postdoc position.
I am interested in studying learning and value-based decision making and how cortical and subcortical areas contribute to complex behavior
