An Intracortical Implantable Brain-Computer Interface for Telemetric Real-Time Recording and Manipulation of Neuronal Circuits for Closed-Loop Intervention.
(Frontiers in human neuroscience, 2021-01)Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces ... -
Attentional Biases in Value-Based Decision-Making
(2014)Humans make decisions in highly complex physical, economic and social environments. In order to adaptively choose, the human brain has to learn about- and attend to- sensory cues that provide information about the potential ... -
Cortical Brain Activity Reflecting Attentional Biasing Toward Reward-Predicting Cues Covaries with Economic Decision-Making Performance.
(Cereb Cortex, 2016-01)Adaptive choice behavior depends critically on identifying and learning from outcome-predicting cues. We hypothesized that attention may be preferentially directed toward certain outcome-predicting cues. We studied this ... -
Evaluating Human Performance in Virtual Reality Based on Psychophysiological Signal Analysis
(2018)Physiological signals measured from the body, such as brain activity and motor behavior, can be used to infer different physiological states or processes in humans. Signal processing and machine learning often play a fundamental ... -
Fusion Methods for Detecting Neural and Pupil Responses to Task-relevant Visual Stimuli Using Computer Pattern Analysis
(2008-04-16)A series of fusion techniques are developed and applied to EEG and pupillary recording analysis in a rapid serial visual presentation (RSVP) based image triage task, in order to improve the accuracy of capturing single-trial ... -
Improvement in visual search with practice: mapping learning-related changes in neurocognitive stages of processing.
(J Neurosci, 2015-04-01)Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus-response ... -
Interactions of Attention, Stimulus Conflict, and Multisensory Processing
(2012)At every moment in life we are receiving input from multiple sensory modalities. We are limited, however, in the amount of information we can selectively attend to and fully process at any one time. The ability to integrate ... -
Internal vs. External Attention and the Neurocognitive Processes of Subsequent Memory
(2018-04-25)The capacity to store large amounts of information is increasingly relevant in today’s data-saturated society. Two subtypes of our attentional mechanisms are known as internal and external attention, and are respectively ... -
Intraoperative Frontal Alpha-Band Power Correlates with Preoperative Neurocognitive Function in Older Adults.
(Front Syst Neurosci, 2017)Each year over 16 million older Americans undergo general anesthesia for surgery, and up to 40% develop postoperative delirium and/or cognitive dysfunction (POCD). Delirium and POCD are each associated with decreased quality ... -
Memory encoding and retrieval: The role of attention, representations and networks
(2020)Episodic memory, as a cognitive construct, exists only in relation to those other cognitive constructs that reference it. It is, as Ribot suggests: the tactile, the muscular, the auditory and so forth. And it is even more ... -
The Dynamic Interplay Between Attention and Reward
(2022)Over the past decade there has been an explosion of interest in exploring how attention and reward value can interact with one another during cognition and behavior. This interdisciplinary work has already provided many ... -
The neural dynamics of stimulus and response conflict processing as a function of response complexity and task demands.
(Neuropsychologia, 2016-04)Both stimulus and response conflict can disrupt behavior by slowing response times and decreasing accuracy. Although several neural activations have been associated with conflict processing, it is unclear how specific any ... -
Uncovering the Neural Basis for Bradykinesia in Parkinson’s disease: Causality of Beta-frequency Oscillations
(2018)Substantial correlative evidence links the synchronized, oscillatory neural firing patterns that emerge in Parkinson’s disease (PD) in the frequency range of 13-30Hz (termed “beta band”) with the development of bradykinesia ... -
Use of Machine Learning and Computer Vision Methods for Building Behavioral and Electrophysiological Biomarkers for Brain Disorders
(2023)Research on biomarkers of brain disorders is an actively developing area. Biomarkers may allow for the early detection of diseases, which is essential for early intervention and improved outcomes. Biomarkers for monitoring ...
