From Parallel Sequence Representations to Calligraphic Control: A Conspiracy of Neural Circuits [PDF]
, 2004 Calligraphic writing presents a rich set of challenges to the human movement control system. These challenges include: initial learning, and recall from memory, of prescribed stroke sequences; critical timing of stroke onsets and durations; fine control

Antidepressant Effects of (S)-Ketamine through a Reduction of Hyperpolarization-Activated Current Ih
iScience, 2020 Summary: Compelling evidence suggests that a single sub-anesthetic dose of (R,S)-ketamine exerts rapid and robust antidepressant effects. However, the cellular mechanisms underlying the antidepressant effects of (R,S)-ketamine remain unclear.

In Synch but Not in Step: Circadian Clock Circuits Regulating Plasticity in Daily Rhythms [PDF]
, 2016 The suprachiasmatic nucleus (SCN) is a network of neural oscillators that program daily rhythms in mammalian behavior and physiology. Over the last decade much has been learned about how SCN clock neurons coordinate together in time and space to form a ...

Quantitative assessment of prefrontal cortex in humans relative to nonhuman primates [PDF]
, 2018 Significance A longstanding controversy in neuroscience pertains to differences in human prefrontal cortex (PFC) compared with other primate species; specifically, is human PFC disproportionately large? Distinctively human behavioral capacities

Numerosity perception is tuned to salient environmental features
iScience, 2022 Summary: Numerosity perception is a key ability to guide behavior. However, current models propose that number units encode an abstract representation of numerosity regardless of the non-numerical attributes of the stimuli, suggesting rather coarse ...
