Article Abstract
Previous research has demonstrated that the dorsal visual stream is able to execute rapid online movement corrections to sudden changes in target position. This "automatic pilot" can operate in the absence of visual awareness, and even under circumstances where participants are instructed to not correct their movements. In the current study, we examined the extent to which these "automatic" corrections might be related to individual differences in executive function. To examine this, healthy adult participants (n = 80) completed two versions of the automatic pilot task on a touch screen: (1) a "Correct" condition in which participants were instructed to correct their movement to the new target location on jump trials, and (2) an "Ignore" condition in which participants were told to ignore any target jumps, and point to the initial target location. In addition to completing these two versions of the automatic pilot task, participants also completed the Sustained Attention to Response Task (SART), in which they were asked to respond when a number was presented, except for the number 3. Finally, participants completed self-report questionnaires indexing executive attention, impulsivity, and executive function including the Adult ADHD Self Report Scale (ASRS), the Cognitive Failures Questionnaire (CFQ), and the Behavioural Rating Inventory of Executive Function for Adults (BRIEF-A).Our results indicated that, similar to previous research, participants made significantly more corrections to target jumps in the "Correct" condition, compared to the "Ignore" condition. Importantly, "automatic" unintended corrections in the "Ignore" condition were significantly correlated with poorer scores on the ASRS, the CFQ and the BRIEF-A. However, unintended corrections were not correlated with errors or reaction times on the SART. These results suggest that the automatic pilot task is sensitive to self-reported individual differences in executive function, and may be useful as a visuomotor measure of response inhibition and cognitive control in both healthy and clinical populations.

Coupling of Event-Related Potential and Pupil Dilation as a Compensatory Marker of Executive Attention in Traumatic Brain Injury.

Traumatic brain injury (TBI) impairs attention and executive function, often through disrupted coordination between cognitive and autonomic systems. While electroencephalography (EEG) and pupillometry are widely used to assess neural and autonomic responses independently, little is known about how these systems interact in TBI. Understanding their coordination is essential to identify compensatory mechanisms that may support attention under conditions of neural inefficiency.

Introduction: This study investigates four subdomains of executive functioning-initiation, cognitive inhibition, mental shifting, and working memory-using task-based functional magnetic resonance imaging (fMRI) data and graph analysis.
Methods: We used healthy adults' functional magnetic resonance imaging (fMRI) data to construct brain connectomes and network graphs for each task and analyzed global and node-level graph metrics.
Results: The bilateral precuneus and right medial prefrontal cortex emerged as pivotal hubs and influencers, emphasizing their crucial regulatory role in all four subdomains of executive function.

Ketamine for Depression, but at What Cost? A Review of Ketamine's Neurotoxic Effects From Preclinical and Human Studies.

This review examines ketamine's neurotoxic potential across preclinical and clinical studies. The authors synthesized data from preclinical models, then integrated findings from human clinical trials of esketamine and observational studies in recreational users. Animal studies have found that repeated or high-dose subanesthetic ketamine administration results in consistent excitotoxic neuronal damage and lasting cognitive deficits, especially in perinatal animals.

Aim: To systematically review neurocognitive outcomes associated with postoperative paediatric cerebellar mutism syndrome (pCMS), comparing children with and without pCMS after posterior fossa tumour surgery, and in relation to moderating demographic and clinical risk factors.
Method: PsycInfo, Medline, and Embase databases were systematically searched up to December 2024. Studies of children aged 2 to 18 years with pCMS who had undergone standardized neurocognitive assessment were included.
