This study finds that adolescents with specific learning disorders show reduced face working memory precision and systematic bias toward neutrality when recalling emotionally valenced faces, with dyscalculia showing the greatest impairment.

This study finds that adolescent chess players show improved rule-guided flexibility and visual working memory precision compared to non-players.

This study examines the impact of a 15-day synbiotic intervention on cognitive functions in healthy young women, finding selective improvements in visual attention but not in working memory or inhibitory control.

This study uses a continuous probabilistic reversal learning task to show that reward-based learning peaks earlier than rule-based learning across the lifespan.

This study examines auditory working memory and metacognitive monitoring in adolescents with specific learning disorders, finding deficits in auditory processing, decision-making, and confidence ratings.

The paper investigates SF coding in the IT cortex of macaque monkeys and finds that SF representation is distinct from category coding, with SF profiles predicting category selectivity at the population level.

This study finds IBS patients selectively avoid bloating-related stimuli, with anxiety modulating this bias but not causing it, highlighting gut-brain interactions in cognitive-emotional processing.

This study compares visual working memory for faces between children with ASD and typically developing children, finding poorer precision in memory recall among ASD children.

This systematic review examines attentional deficits and brain-gut axis interactions in IBS patients, identifying attentional biases and altered brain activation patterns.

A single session of fast-paced video gaming improves working-memory precision and increases prefrontal alpha oscillations.

This study investigates how emotional content affects working memory precision, finding a negativity bias and altered perception of emotional valence.

This study examines conscious and unconscious emotional processing through behavioral and pupillary responses, finding distinct patterns in accuracy, pupil size, and task parameters between states.

This paper presents a low-cost protocol to recondition neural microelectrodes with material failure, demonstrating its effectiveness through experimental results on tungsten electrodes.

This study shows that aging reduces the precision of visual working memory, with increased error variability but no change in random response probability.

The paper investigates how spatial frequency affects category representation in the macaque IT cortex, finding that mid-level categories are robust across spatial frequencies while high spatial frequencies are critical for superordinate categories.

The paper shows that coordination between prefrontal and temporal cortex, measured by phase-locking of spikes and LFPs, predicts working memory performance and object-selective persistent activity.
