Linking abnormal neural activity patterns to motor deficits by Herzfeld, David J

“…Abnormal activity in the cerebellar nuclei can be used to predict motor symptoms and induce them experimentally, pointing to potential therapeutic strategies…”

A memory of errors in sensorimotor learning by Herzfeld, David J., Vaswani, Pavan A., Marko, Mollie K., Shadmehr, Reza

“…The current view of motor learning suggests that when we revisit a task, the brain recalls the motor commands it previously learned. In this view, motor memory…”

Behavioral training of marmosets and electrophysiological recording from the cerebellum by Sedaghat-Nejad, Ehsan, Herzfeld, David J, Hage, Paul, Karbasi, Kaveh, Palin, Tara, Wang, Xiaoqin, Shadmehr, Reza

“…The common marmoset ( ) is a promising new model for study of neurophysiological basis of behavior in primates. Like other primates, it relies on saccadic eye…”

An implicit memory of errors limits human sensorimotor adaptation by Albert, Scott T., Jang, Jihoon, Sheahan, Hannah R., Teunissen, Lonneke, Vandevoorde, Koenraad, Herzfeld, David J., Shadmehr, Reza

“…During extended motor adaptation, learning appears to saturate despite persistence of residual errors. This adaptation limit is not fixed but varies with…”

Principles of operation of a cerebellar learning circuit by Herzfeld, David J, Hall, Nathan J, Tringides, Marios, Lisberger, Stephen G

“…We provide behavioral evidence using monkey smooth pursuit eye movements for four principles of cerebellar learning. Using a circuit-level model of the…”

Motor variability is not noise, but grist for the learning mill by Herzfeld, David J, Shadmehr, Reza

“…A study demonstrates that variability in how people perform a movement can predict the rate of motor learning on an individual basis. This suggests that motor…”

Rate versus synchrony codes for cerebellar control of motor behavior by Herzfeld, David J., Joshua, Mati, Lisberger, Stephen G.

“…Information transmission between neural populations could occur through either coordinated changes in firing rates or the precise transmission of spike timing…”

Evaluation and resolution of many challenges of neural spike sorting: a new sorter by Hall, Nathan J, Herzfeld, David J, Lisberger, Stephen G

“…We evaluate existing spike sorters and present a new one that resolves many sorting challenges. The new sorter, called "full binary pursuit" or FBP, comprises…”

Movement vigor as a traitlike attribute of individuality by Reppert, Thomas R, Rigas, Ioannis, Herzfeld, David J, Sedaghat-Nejad, Ehsan, Komogortsev, Oleg, Shadmehr, Reza

“…A common aspect of individuality is our subjective preferences in evaluation of reward and effort. The neural circuits that evaluate these commodities…”
