New preprint. We show that in addition to reward prediction errors (RPEs), dorsal striatal dopamine signals encode sensory prediction errors (SPEs), the difference between sensory prior & observed stimulus. www.biorxiv.org/content/10.6...
Dorsal striatal dopamine integrates sensory and reward prediction errors to guide perceptual decisions
Perceptual decisions are shaped by expectations about sensory stimuli and rewards, learned through sensory and reward prediction errors. Dopamine is known to convey reward prediction errors that shape...

For 2026, I dare the human & rodent behavioral & cognitive neuroscience communities to find one NHP paper relevant to your research & cite it regularly next year when writing up your manuscripts. If you already cite one, find another one and double up. #Neuroskyence bsky.app/profile/vinc...
I definitely didn’t just scrape the web to get the h-index and total citation count as of 12/30/2025 for 319 living and dead nonhuman primate researchers to get a sense of publication metrics by rank on tenure-track.

Unfortunately this study, while heroic in many ways, does not take into account cardiac, respiration and other vasomotor effects, all of which have spatial signatures. Nor is there an electrophysiological measure of neural activity. Be careful before throwing the baby out with the bath water.

"drug for disorder which isn't a disorder doesn't act on a brain network (which isn't a network) called as the thing in the name of said not-disorder, according to increased signal detected by a method in which increased signal possibly doesn't indicate increased activation"
I don't think there's an attention deficit, I don't think hyperactivity is a primary issue ... and I'm not sure it's a disorder. I think it's a relatively lower tolerance for activities with low predicted rewards. which leads to new activity seeking manifesting as movement.

So reindeer (Rangifer tarandus) can't fly, but they are VERY MAGICAL.
For example, their EYES CHANGE COLOR during the year & they're one of the few large mammals that can see UV. Golden brown in summer, deep blue in winter.

We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor?
