Ramping activity and reward I realized that I never posted about this awesome paper, which quantifies contributions of movement, reward anticipation, and timing to cortical and striatal ramping activity:

Congratulations to Hannah Stutt! This is much too late - but congrats to Hannah Stutt for defending her PhD earlier this year. She will join Austin Coley's lab at UCLA.

I've been quiet on social media recently - but I miss the opportunity to talk about all the cool things happening with other scientists since the days of Twitter. So - congrats to Hannah Stutt on defending her PhD on dorsal striatal dopamine and timing. Next step: on to awesome postdoctoral work!

Our latest work: www.biorxiv.org/content/10.1... We show that corticostriatal ramping activity can't readily be explained by movements using motion tracking, and that ramping can't readily be explained by reward anticipation in mice performing timing and Pavlovian tasks.

Timing, movement, and reward contributions to prefrontal and striatal ramping activity
Across species, prefrontal and striatal neurons exhibit time-dependent ramping activity, defined as a consistent monotonic change in firing rate across temporal intervals. However, it is unclear if ra...

Wild - the term 'prefrontal' I think first appeared in 1878 in the journal Brain relating Phineas Gage and other lesions. For the human chauvinists out there - I think the term originates from fish skull anatomy, and in the first description - animal references abound:
