Event-Related Potentials Dissociate Effects of Salience and Space in Biased Competition for Visual Representation
It is suggested that N2pc and PTC components may index distinct processes of biased competition—N2pc reflecting visual competitive interactions and Ptc reflecting a bias in processing necessary to individuate task-relevant stimuli.

The N2pc results are consistent with the idea that spatially mediated competition for representation in extrastriate cortex degrades target selection, and may reflect a bias signal needed to resolve the competition at smaller target-decoy separations.
Frontal Theta Cordance Predicts 6-Month Antidepressant Response to Subcallosal Cingulate Deep Brain Stimulation for Treatment-Resistant Depression: A Pilot Study
Results from this pilot study suggest that baseline FTC and changes early in treatment each have utility as biomarkers for predicting 6-month clinical response to SCC DBS for TRD.
Dynamics of target and distractor processing in visual search: Evidence from event-related brain potentials
Electrophysiological correlates of presaccadic remapping in humans.
Electrophysiological correlates of remapping in humans using event-related potentials are investigated, finding results consistent with interhemispheric remapping of visual space in anticipation of an upcoming saccade.
Enhancement and suppression in the visual field under perceptual load
Estimation of the distribution of load-induced distractor suppression and task-relevant enhancement in the visual field using steady-state visual evoked potentials in conjunction with time-domain event-related potentials revealed a significant increase in N1 amplitude under high load.

Age-related differences in the perceptual boost received by probes appearing over facial expressions of emotion are investigated, finding that for young adults, the visual system was more active when the probes appeared over any of the emotional facial expressions, but for older adults,the visual system displayed reduced activity.
Steady-state Signatures of Visual Perceptual Load, Multimodal Distractor Filtering, and Neural Competition
Analysis of task-related signals revealed that visual distractors competed with task stimuli for representation and that increased perceptual load appeared to resolve this competition in favor of the task stimulus.
Effects of Subcallosal Cingulate Deep Brain Stimulation on Negative Self-bias in Patients With Treatment-resistant Depression
The Importance of Temporal Distinctiveness for Forgetting Over the Short Term
It is demonstrated that performance after a long delay can be better than performance after an short delay if the temporal confusability between the current item and previous items is reduced.
