A quantitative comparison of NIRS and fMRI across multiple cognitive tasks

X Cui, S Bray, DM Bryant, GH Glover, AL Reiss - Neuroimage, 2011 - Elsevier
Near infrared spectroscopy (NIRS) is an increasingly popular technology for studying brain
function. NIRS presents several advantages relative to functional magnetic resonance …

Functional near infrared spectroscopy (NIRS) signal improvement based on negative correlation between oxygenated and deoxygenated hemoglobin dynamics

X Cui, S Bray, AL Reiss - Neuroimage, 2010 - Elsevier
Near infrared spectroscopy (NIRS) is a promising technology for functional brain imaging
which measures hemodynamic signals from the cortex, similar to functional magnetic …

Neural coding of reward-prediction error signals during classical conditioning with attractive faces

S Bray, J O'Doherty - Journal of neurophysiology, 2007 - journals.physiology.org
Attractive faces can be considered to be a form of visual reward. Previous imaging studies
have reported activity in reward structures including orbitofrontal cortex and nucleus …

The neural mechanisms underlying the influence of pavlovian cues on human decision making

S Bray, A Rangel, S Shimojo, B Balleine… - Journal of …, 2008 - Soc Neuroscience
In outcome-specific transfer, pavlovian cues that are predictive of specific outcomes bias
action choice toward actions associated with those outcomes. This transfer occurs despite no …

[HTML][HTML] Morphological alterations in the thalamus, striatum, and pallidum in autism spectrum disorder

…, FP MacMaster, MM Chakravarty, SL Bray - …, 2016 - nature.com
Autism spectrum disorder (ASD) is a common neurodevelopmental disorder with cognitive,
motor, and emotional symptoms. The thalamus and basal ganglia form circuits with the cortex …

Direct instrumental conditioning of neural activity using functional magnetic resonance imaging-derived reward feedback

S Bray, S Shimojo, JP O'Doherty - Journal of Neuroscience, 2007 - Soc Neuroscience
Successful learning is often contingent on feedback. In instrumental conditioning, an animal
or human learns to perform specific responses to obtain reward. Instrumental conditioning is …

[HTML][HTML] Reduced intrinsic connectivity of amygdala in adults with major depressive disorder

R Ramasubbu, N Konduru, F Cortese, S Bray… - Frontiers in …, 2014 - frontiersin.org
Imaging studies of major depressive disorder (MDD) have demonstrated enhanced resting-state
activity of the amygdala as well as exaggerated reactivity to negative emotional stimuli …

Efficacy of adjunctive D-cycloserine to intermittent theta-burst stimulation for major depressive disorder: a randomized clinical trial

J Cole, MN Sohn, AD Harris, SL Bray, SB Patten… - JAMA …, 2022 - jamanetwork.com
Importance The antidepressant effects of transcranial magnetic stimulation protocols for
major depressive disorder (MDD) are thought to depend on synaptic plasticity. The theta-burst …

[HTML][HTML] Speeded near infrared spectroscopy (NIRS) response detection

X Cui, S Bray, AL Reiss - PLoS one, 2010 - journals.plos.org
The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally
delayed from the onset of the underlying neural activity. As a consequence, NIRS based …

Human medial orbitofrontal cortex is recruited during experience of imagined and real rewards

S Bray, S Shimojo, JP O'Doherty - Journal of …, 2010 - journals.physiology.org
Human decision-making frequently relies on mental simulation of future rewards to guide
action choice. In this study, we sought to uncover brain regions engaged during reward …
