A Pilot Study Using Two Novel fMRI Tasks: Understanding Theory of Mind and Emotion Recognition Among Children With ASD

This study uses fMRI to examine theory of mind and emotion recognition in children with ASD compared to neurotypical children, finding impairments in ToM metrics and brain deficits related to emotion processing.

Effects of prefrontal tDCS on dopamine-mediated behavior and psychophysiology

This study investigates whether prefrontal tDCS affects dopamine-related behaviors and physiology, finding no significant effects but suggesting individual differences may influence responses.

Multimodal-Multisensory Experiments: Design and Implementation

This paper introduces an open-source framework for designing and implementing multimodal-multisensory human experiments using PsychoPy, Unity, and Lab Streaming Layer.

Cerebellar and Prefrontal-Cortical Engagement During Higher-Order Rule Learning in Older Adulthood

This study compares cerebellar and prefrontal-cortical activity during a second-order learning task in young adults and older adults, finding age-related differences in activation patterns.

Dissociable Cerebellar-Prefrontal Networks Underlying Executive Function: Evidence from the Human Connectome Project

The paper examines cerebellar-prefrontal networks in executive function using Human Connectome Project data, finding dissociable connectivity patterns between posterior cerebellar regions and lateral prefrontal cortex areas.

Striatal-frontal network activation during voluntary task selection under conditions of monetary reward

This study examines brain activation during voluntary task selection under monetary reward conditions and finds that transient rewards influence neural activity in reward and executive function regions without affecting task choice behavior.
