Use of Salvia divinorum in a nationally representative sample.
(The American journal of drug and alcohol abuse, 2012-01)
Salvia divinorum has known hallucinogenic effects and is legal in most parts of the
United States. Given that this psychoactive substance has a potential of misuse and
abuse, further data regarding the clinical and psychosocial ...
Mental Health and Substance Use Among Patients in a North Carolina HIV Clinic.
(N C Med J, 2015-07)
BACKGROUND: The HIV/AIDS epidemic is a significant public health concern in North
Carolina, and previous research has pointed to elevated mental health distress and
substance use among HIV-infected populations, which may ...
The spatiotemporal dynamics of autobiographical memory: neural correlates of recall, emotional intensity, and reliving.
(Cereb Cortex, 2008-01)
We sought to map the time course of autobiographical memory retrieval, including brain
regions that mediate phenomenological experiences of reliving and emotional intensity.
Participants recalled personal memories to auditory ...
Brain activity during episodic retrieval of autobiographical and laboratory events: an fMRI study using a novel photo paradigm.
(J Cogn Neurosci, 2004-11)
Functional neuroimaging studies of episodic memory retrieval generally measure brain
activity while participants remember items encountered in the laboratory ("controlled
laboratory condition") or events from their own life ...
Neural responses to emotional involuntary memories in posttraumatic stress disorder: Differences in timing and activity.
(NeuroImage. Clinical, 2018-01)
Background:Involuntary memories are a hallmark symptom of posttraumatic stress disorder
(PTSD), but studies of the neural basis of involuntary memory retrieval in posttraumatic
stress disorder (PTSD) are sparse. The study ...
Complementary topology of maintenance and manipulation brain networks in working memory.
(Scientific reports, 2018-12-13)
Working memory (WM) is assumed to consist of a process that sustains memory representations
in an active state (maintenance) and a process that operates on these activated representations
(manipulation). We examined evidence ...
Co-activation of the amygdala, hippocampus and inferior frontal gyrus during autobiographical memory retrieval.
(Neuropsychologia, 2005)
Functional MRI was used to investigate the role of medial temporal lobe and inferior
frontal lobe regions in autobiographical recall. Prior to scanning, participants generated
cue words for 50 autobiographical memories and ...
Rapid brain responses independently predict gain maximization and loss minimization during economic decision making.
(J Neurosci, 2013-04-17)
Success in many decision-making scenarios depends on the ability to maximize gains
and minimize losses. Even if an agent knows which cues lead to gains and which lead
to losses, that agent could still make choices yielding ...
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 ...
The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)
In this study, we leveraged the high temporal resolution of EEG to examine the neural
mechanisms underlying the flexible regulation of cognitive control that unfolds over
different timescales. We measured behavioral and ...
