More details: Come hear about my work isolating a corticostriatal locus of birdsong learning - and how I leveraged this localization to make birds learn faster! #SfN25
Early Career TPDA Poster session: Sat. night 6:45-8:45pm, poster H6

Woolly bear gang (Isabella Tiger Moth) Look at those teeny feet!
Also, there is folklore that the length of the black band predicts how harsh of a winter it will be - looks like a mild one

Congrats to a legend of neuroanatomy! Her findings are foundational and her figures (or those inspired by them) are fixtures of basal ganglia talks

This is supported by pharmacological DA blockade affecting learning but not movement parameters. Konstantin's work is persuasive, and it's clear that at least some of the RPE literature can be explained by movement kinematics, and more careful measurement of these parameters is def. needed (4/5)

Analysis of the timing of DA transients found parameter-related DA is aligned with syllable onset (left), but the PE signal lags by ~200ms (right). This makes sense: PEs have to occur *after* the behavior that caused them - in the bird's case after he hears his song and judges its quality (2/5)

Always wondered what these gorgeous ducks at Duke Gardens were. Finally figured out they are Ruddy Shelducks native to Asia - must've been brought here?

And, to beat a dead horse, correlation with a behavior does not necessarily align with a functional role in that behavior, which Musall et al also show. Of course, cell types ≠ brain areas, so this is still consistent with claiming that brain areas aren't the primary organizational unit (2/x)

It's important to pick a substrate that matches your camouflage - the katydid knows what's up, the moth...less so
