The representation and valuation of subgoals in the human brain during model-based hierarchical behavior
The human capacity to plan and perform long, complex sequences of behavior to achieve distant goals depends in part on a hierarchical organization that divides behavior into structured segments. Such ...

my first human/fmri pre-print is out. in it, we provide some insight into how the brain persistently represents subgoals and evaluates choices in relation to those subgoals during behavior that is both hierarchical and model-based.

new paper from a collaborative endeavor! (@co0p3r.bsky.social) we find & replicate food-reward biases in a reinforcement learning task (where food stim are incidental)
people with eating disorder symptoms show a low-calorie food bias while those without show a high-calorie food bias... (1/3)

Eating disorder symptoms and emotional arousal modulate food biases during reward learning in females - Nature Communications
Disordered eating can disrupt the rewarding value of food. Here, the authors show in a female sample that eating disorder symptoms, emotional arousal, and interoceptive awareness modulate goal-ir...

I'm excited to share that the last chapter of my PhD thesis is now published in Nature! 🍾
What drives serotonin neurons? We think it's the expectation of future reward and --- critically --- how fast this expectation is increasing. 📈

A prospective code for value in the serotonin system - Nature
Merging ideas from reinforcement learning theory with recent insights into the filtering properties of the dorsal raphe nucleus, a unifying perspective is found explaining why serotonin neurons are ac...
