Aggression elicited by social rejection is costly, prevalent, and often lethal. Attempts to predict rejection-elicited aggression using trait-based data have had little success. This may be because in-the-moment aggression is a complex process influenced by current states of attention, arousal, and affect which are poorly predicted by trait-level characteristics.

Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune disorder typically characterized by seizures, movement abnormalities, and behavioral changes. Anti-N-methyl-D-aspartate can present with complex neuropsychiatric symptoms including catatonia which can be challenging for clinicians to identify as excited catatonia can mimic delirium and psychiatric disorders such as psychosis and mania.

We hypothesized that decreasing R PTr excitability would reduce interference with word finding, facilitating faster picture naming. 15 older and 16 younger adults received two rTMS sessions.

However, additional considerations in the chronic stages of stroke require exploration including time since stroke, gender, intracortical volume, aging, and lesion volume to better characterize thalamic differences after cortical infarct. This cross-sectional retrospective study quantified the ipsilesional and contralesional thalamus volume from 69 chronic stroke subjects' anatomical MRI data (age 35-92) and related the thalamus volume to time since stroke, gender, intracortical volume, age, and lesion volume.
