[HTML][HTML] The human amygdala parametrically encodes the intensity of specific facial emotions and their categorical ambiguity

…, Y Huang, R Hurlemann, IB Ross, JM Chung… - Nature …, 2017 - nature.com
The human amygdala is a key structure for processing emotional facial expressions, but it

The geometry of domain-general performance monitoring in the human medial frontal cortex

Z Fu, D Beam, JM Chung, CM Reed, AN Mamelak… - Science, 2022 - science.org
Controlling behavior to flexibly achieve desired goals depends on the ability to monitor one’s
own performance. It is unknown how performance monitoring can be both flexible, to …

[PDF][PDF] Single-neuron correlates of error monitoring and post-error adjustments in human medial frontal cortex

Z Fu, DAJ Wu, I Ross, JM Chung, AN Mamelak… - Neuron, 2019 - cell.com
Humans can self-monitor errors without explicit feedback, resulting in behavioral adjustments
on subsequent trials such as post-error slowing (PES). The error-related negativity (ERN) …

Working memory load-related theta power decreases in dorsolateral prefrontal cortex predict individual differences in performance

…, J Kamiński, CM Reed, JM Chung… - Journal of cognitive …, 2019 - direct.mit.edu
Holding information in working memory (WM) is an active and effortful process that is accompanied
by sustained load-dependent changes in oscillatory brain activity. These proportional …

[HTML][HTML] Dataset of human-single neuron activity during a Sternberg working memory task

M Kyzar, J Kamiński, A Brzezicka, CM Reed, JM Chung… - Scientific Data, 2024 - nature.com

Extent of single-neuron activity modulation by hippocampal interictal discharges predicts declarative memory disruption in humans

…, CP Mosher, N Chandravadia, JM Chung… - Journal of …, 2020 - Soc Neuroscience
Memory deficits are common in epilepsy patients. In these patients, the interictal EEG commonly
