very excited to share some of the final bits of work from my PhD! 🎉 we find that phasic DA in the accumbens simultaneously tracks persistent motivation towards reward cues in addition to new learning (but maybe not RPE?!) in sign-tracking rats. check out the preprint below!
Phasic dopamine encodes persistent attraction to reward cues https://www.biorxiv.org/content/10.64898/2025.12.09.693300v1

I am excited to announce (belatedly) that my dissertation’s final chapter has been published in the Journal of Neuroscience! doi.org/10.1523/JNEU...
Hemifield Specificity of Attention Response Functions during Multiple-Object Tracking
The difficulty of tracking multiple moving objects among identical distractors increases with the number of tracked targets. Previous research has shown that the number of targets tracked (i.e., load)...
