Emotion circuits in the brain.
Annual Review of Neuroscience, 2009The field of neuroscience has, after a long period of looking the other way, again embraced emotion as an important research area. Much of the progress has come from studies of fear, and especially fear conditioning. This work has pinpointed the amygdala

Conn: A Functional Connectivity Toolbox for Correlated and Anticorrelated Brain Networks
Brain Connectivity, 2012Resting state functional connectivity reveals intrinsic, spontaneous networks that elucidate the functional architecture of the human brain. However, valid statistical analysis used to identify such networks must address sources of noise in order to ...

Journal of Child Neurology, 2012
For the past 50 years, the medical profession has understood ‘‘brain death’’ to represent the endpoint of a neuropathologic vicious cycle. An initial major brain injury sets off a mutually exacerbating cascade of cerebral edema, increased intracranial pressure, and decreased cerebral blood flow, which advances beyond some point-of-no-return to a state ...

Annual Review of Neuroscience, 2006
Functional brain imaging with positron emission tomography and magnetic resonance imaging has been used extensively to map regional changes in brain activity. The signal used by both techniques is based on changes in local circulation and metabolism (brain work).

Journal of Cognitive Neuroscience, 2003
AbstractThe aims of the present study were to investigate whether the processing of an object shadow occurs implicitly, that is without conscious awareness, and where physically within the human brain shadows are processed. Here we present neurological evidence, obtained from studies of brain-injured patients with visual neglect, that shadows are ...

The attention system of the human brain.
Annual Review of Neuroscience, 1990Illustration de trois fonctions principales qui sont predominantes dans l'etude de l'intervention de l'attention dans les processus cognitifs: 1) orientation vers des evenements sensoriels; 2) detection des signaux par processus focal; 3) maintenir la ...

Physiology and neurobiology of stress and adaptation: central role of the brain.
Physiological Reviews, 2007The brain is the key organ of the response to stress because it determines what is threatening and, therefore, potentially stressful, as well as the physiological and behavioral responses which can be either adaptive or damaging.

Brain Plasticity in the Developing Brain
2013The developing normal brain shows a remarkable capacity for plastic change in response to a wide range of experiences including sensory and motor experience, psychoactive drugs, parent-child relationships, peer relationships, stress, gonadal hormones, intestinal flora, diet, and injury.
