Journal ArticleDOI
Gaze fixation and the neural circuitry of face processing in autism
Kim M. Dalton,Brendon M. Nacewicz,Tom Johnstone,Hillary S. Schaefer,Morton Ann Gernsbacher,H. Hill Goldsmith,Andrew L. Alexander,Richard J. Davidson +7 more
TL;DR: Variation in eye fixation within autistic individuals was strongly and positively associated with amygdala activation across both studies, suggesting a heightened emotional response associated with gaze fixation in autism.
Journal ArticleDOI
Amygdala and ventromedial prefrontal cortex are inversely coupled during regulation of negative affect and predict the diurnal pattern of cortisol secretion among older adults
Heather L. Urry,Carina Marije Van Reekum,Tom Johnstone,Ned H. Kalin,Marchell E. Thurow,Hillary S. Schaefer,Cory A. Jackson,Corrina Frye,Lawrence L. Greischar,Andrew L. Alexander,Richard J. Davidson +10 more
TL;DR: Individual differences yielded the predicted link between brain function while reducing negative affect in the laboratory and diurnal regulation of endocrine activity in the home environment.
Journal ArticleDOI
Lending a Hand Social Regulation of the Neural Response to Threat
TL;DR: Results indicated a pervasive attenuation of activation in the neural systems supporting emotional and behavioral threat responses when the women held their husband's hand, and most strikingly, the effects of spousal hand-holding on neural threat responses varied as a function of marital quality.
Journal ArticleDOI
Neural correlates of attentional expertise in long-term meditation practitioners
Julie A. Brefczynski-Lewis,Antoine Lutz,Hillary S. Schaefer,Daniel B. Levinson,Richard J. Davidson +4 more
TL;DR: In age-matched participants, using functional MRI, it was found that activation in a network of brain regions typically involved in sustained attention showed an inverted u-shaped curve in which expert meditators (EMs) with an average of 19,000 h of practice had more activation than novices, but EMs with anAverage of 44,000H had less activation.
Journal ArticleDOI
Functional neuroanatomy of aversion and its anticipation.
Jack B. Nitschke,Issidoros Sarinopoulos,Kristen L. Mackiewicz,Hillary S. Schaefer,Richard J. Davidson +4 more
TL;DR: Results show that anticipation of aversion recruits key brain regions that respond to aversion, thereby potentially enhancing adaptive responses to aversive events.
