Rapid brain responses to affective pictures indicate dimensions of trauma‐related psychopathology in adolescents

Brain response to affective pictures in the chimpanzee

Advancement of non-invasive brain imaging techniques has allowed us to examine details of neural activities involved in affective processing in humans; however, no comparative data are available for chimpanzees, the closest living relatives of humans. In the present study, we measured event-related brain potentials in a fully awake adult chimpanzee as she looked at affective and neutral picture...

Characteristics of Brain Wave Changes by Affective Pictures

Emotion status influences important areas in our daily lives. Many researchers reported successful emotion classifications. The aim of this study is to find out the neurophysiological characteristics of the brain waves while affective pictures elucidate emotion. Four healthy college students volunteered the stimulus experiment with the standard IAPS affective pictures. All brain waves showed ac...

Linked dimensions of psychopathology and connectivity in functional brain networks

1 Neurobiological abnormalities associated with psychiatric disorders do not map well to existing diagnostic 2 categories. High co-morbidity and overlapping symptom domains suggest dimensional circuit-level 3 abnormalities that cut across clinical diagnoses. Here we sought to identify brain-based dimensions of 4 psychopathology using multivariate sparse canonical correlation analysis (sCCA) in ...

Watching affective Pictures

Affective reactions to briefly presented pictures.

Affective reactions to briefly presented pictures were investigated to determine whether fleeting stimuli engage the motivational systems mediating emotional responses. Emotional and neutral pictures were presented for 500 ms; heart rate, skin conductance, corrugator EMG, and the evoked startle reflex were measured. The time course of reflex modulation was similar to that obtained with longer (...
