Differential developmental trajectories of magnetic susceptibility in human brain gray and white matter over the lifespan.
(Hum Brain Mapp, 2014-06)
As indicated by several recent studies, magnetic susceptibility of the brain is influenced mainly by myelin in the white matter and by iron deposits in the deep nuclei. Myelination and iron deposition in the brain evolve ...
Activation in mesolimbic and visuospatial neural circuits elicited by smoking cues: evidence from functional magnetic resonance imaging.
(Am J Psychiatry, 2002-06)
OBJECTIVE: The authors sought to increase understanding of the brain mechanisms involved in cigarette addiction by identifying neural substrates modulated by visual smoking cues in nicotine-deprived smokers. METHOD: Event-related ...
The PsychENCODE project.
(Nat Neurosci, 2015-12)
Fear learning circuitry is biased toward generalization of fear associations in posttraumatic stress disorder.
(Transl Psychiatry, 2015-12-15)
Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective ...
Building an organic computing device with multiple interconnected brains.
(Scientific reports, 2015-07-09)
Recently, we proposed that Brainets, i.e. networks formed by multiple animal brains, cooperating and exchanging information in real time through direct brain-to-brain interfaces, could provide the core of a new type of computing ...
The G-protein-coupled receptor kinases beta ARK1 and beta ARK2 are widely distributed at synapses in rat brain.
(J Neurosci, 1992-10)
The beta-adrenergic receptor kinase (beta ARK) phosphorylates the agonist-occupied beta-adrenergic receptor to promote rapid receptor uncoupling from Gs, thereby attenuating adenylyl cyclase activity. Beta ARK-mediated receptor ...
Using functional magnetic resonance imaging in psychotherapy research: a brief introduction to concepts, methods, and task selection.
(Psychother Res, 2009-07)
Functional magnetic resonance imaging (fMRI) has become an increasingly important methodology in the study of psychotherapy outcome and process. In this article, the authors offer a brief introduction to the use of fMRI ...
Neural correlates of emotional processing in depression: changes with cognitive behavioral therapy and predictors of treatment response.
(J Psychiatr Res, 2011-05)
Major depressive disorder (MDD) is characterized by the presence of disturbances in emotional processing. However, the neural correlates of these alterations, and how they may be affected by therapeutic interventions, remain ...
Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.
(J Cogn Neurosci, 2010-11)
Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different ...
Imagery and retrieval of auditory and visual information: neural correlates of successful and unsuccessful performance.
Remembering past events - or episodic retrieval - consists of several components. There is evidence that mental imagery plays an important role in retrieval and that the brain regions supporting imagery overlap with those ...
