🧠 New preprint by Greenstreet, Geerts, Gallego, and Clopath on #MotorLearning across #cortex, #cerebellum, and #BasalGanglia.
Key idea: supervised learning builds a low-dimensional action embedding, and #ReinforcementLearning operates directly in this structured space. This explains generalization, interference, and striatal similarity patterns as geometric consequences, not add-ons.
📣 Now published:
"Auditory-motor adaptation and de-adaptation for speech depend more on time in the new environment than on the amount of practice"

#MotorLearning #Adaptation #Speech #Sensorimotor #MotorControl
Speech auditory-motor adaptation to a formant-shift perturbation and de-adaptation after the perturbation is removed both depend more on total amount of time spent in the corresponding environment than on the number of practice trials.
Learning new movements doesn't just change brain activity—it rewires the brain's circuits. Discover how UC San Diego scientists uncovered this transformation. #Neuroscience #BrainPlasticity #MotorLearning

How do we become the pilots of our own bodies? New research reveals the surprising key to building a sense of agency. #Neuroscience #MotorLearning #HumanExperience

How do we come to feel that our movements are truly our own? A new study reveals that agency arises not from imitation, but from the messy, vital process of trial and error — a finding with big implications for rehabilitation, virtual reality, and more.
Motor learning at #SfN24
It has been almost 10 years now that we have come to the realization that a particular type of our operant experiments can be classified as motor learning. In such "operant self-learning" experiments, the animal learns about the consequences of its own behavior and adjusts future behavior accordingly. In this experiment, a tethered fly, flying stationarily in an otherwise featureless environment, is trained to avoid/prefer one of two turning directions. The fly is tethered to a torque […]
Whodathunk? Motor learning in motor neurons, huh?
I was very excited when our latest research paper came out, after all, I was confident our 30-year-long search for the sites of plasticity in the form of motor learning we study was coming to an end. In this work, we were fairly confident that underlying the type of learning we study was a novel form of plasticity in a very specific set of motor neurons in the ventral nerve cord of the flies we use for our research. The reason for our confidence was the convergence of several lines of [...]

This year, we have two posters for #SFN both in the morning.
On Tuesday, it'll be on optogenetic self-stimulation with Ben deBivort as co-author:

but it'll be mainly the recent work of undergraduate Luisa Guyton.
On Wednesday it'll be on different ways in which we improve #motorlearning in #Drosophila
