Curr Biol
. 2024 Mar;
34(7):1519-1531.e4.
PMID: 38531360
How are we able to learn new behaviors without disrupting previously learned ones? To understand how the brain achieves this, we used a brain-computer interface (BCI) learning paradigm, which enables...

Nature
. 2022 Jan;
602(7896):274-279.
PMID: 35082444
The brain's remarkable ability to learn and execute various motor behaviours harnesses the capacity of neural populations to generate a variety of activity patterns. Here we explore systematic changes in...

Nat Commun
. 2021 Jun;
12(1):3689.
PMID: 34140486
Calcium imaging is a powerful tool for recording from large populations of neurons in vivo. Imaging in rhesus macaque motor cortex can enable the discovery of fundamental principles of motor...

Nat Neurosci
. 2021 Mar;
24(5):727-736.
PMID: 33782622
Internal states such as arousal, attention and motivation modulate brain-wide neural activity, but how these processes interact with learning is not well understood. During learning, the brain modifies its neural...

Proc IEEE Inst Electr Electron Eng
. 2021 Mar;
105(1):66-72.
PMID: 33746239
Brain-computer interfaces (BCIs) record brain activity and translate the information into useful control signals. They can be used to restore function to people with paralysis by controlling end effectors such...

Nature
. 2021 Jan;
591(7851):604-609.
PMID: 33473215
In dynamic environments, subjects often integrate multiple samples of a signal and combine them to reach a categorical judgment. The process of deliberation can be described by a time-varying decision...

Cell Rep
. 2020 Aug;
32(6):108006.
PMID: 32783934
In multiple cortical areas, including the motor cortex, neurons have similar firing rate statistics whether we observe or execute movements. These "congruent" neurons are hypothesized to support action understanding by...

Neuron
. 2020 Feb;
106(2):329-339.e4.
PMID: 32053768
Current theories suggest that an error-driven learning process updates trial-by-trial to facilitate motor adaptation. How this process interacts with motor cortical preparatory activity-which current models suggest plays a critical role...
