A brain network supporting social influences in human decision-making
Humans learn from their own trial-and-error experience and observing others. However, it remains unknown how brain circuits compute expected values when direct learning and social learning coexist in uncertain environments. Using a multiplayer...
Impaired working memory, cognitive flexibility and reward processing in mice genetically lacking Gpr88: evidence for a key role for Gpr88 in multiple cortico‐striatal‐thalamic circuits
The GPR88 orphan G protein‐coupled receptor is expressed throughout the striatum, being preferentially localized in medium spiny neurons. It is also present in lower densities in frontal cortex and t...

Task-evoked pupillary responses track effort exertion: Evidence from task-switching
A spate of research has examined how individuals regulate effortful processing in service of goal-directed behaviors. One key challenge in developing an account of this regulation is quantifying the momentary amount of cognitive effort exerted by an...
Neuroscience Professor Hosting ‘Skype a Scientist’ Livestream | College of Liberal Arts
College of Liberal Arts Neuroscience Assistant Professor Vishnu Murty is hosting a livestream event on Oct. 9 at 1 p.m. During the stream, the professor will discuss the psychology of memory distortion and answer student questions.
Self-competence increases the willingness to pay for social influence
Theoretical works in social psychology and neuroscientific evidence have proposed that social rewards have intrinsic value, suggesting that people place a high premium on the ability to influence others. To test this hypothesis, we asked whether,...
White matter correlates of scam susceptibility in community-dwelling older adults
Scam susceptibility places older adults – even those with intact cognition – at great risk. Lower grey matter volumes, particularly within right medial temporal regions, are associated with higher scam susceptibility; however, very little is known...

Predicting alcohol dependence from multi‐site brain structural measures
To identify neuroimaging biomarkers of alcohol dependence (AD) from structural magnetic resonance imaging, we developed classifiers on data collected from multiple sites. Exploratory data analysis re...
U.S. faculty job market tanks
In February, Ashley Ingiosi was excited to finally interview for a faculty position after spending 10 years in training as a grad student and postdoc. “Then COVID came around,” the Washington State University, Spokane, neuroscientist says, and the...

The effect of functionally-guided-connectivity-based rTMS on amygdala activation.
Repetitive transcranial magnetic stimulation (rTMS) has fundamentally transformed how we treat psychiatric disorders, but is still in need of innovation to optimally correct dysregulation that occurs throughout the fronto-limbic network. rTMS is...

Dopaminergic and opioidergic regulation during anticipation and consumption of social and nonsocial rewards
Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).
