Article Abstract
If perceptual and bodily states are closely linked and if perceiving action automatically leads to corresponding activations in one's own motor system, then why do not we imitate all the time? There is evidence suggesting that executive functioning (EF) may play a moderating role in inhibiting overt imitation [e.g. Luria, A. R. (1966). Higher cortical functions in man. New York: Basic Books]. In an experiment we tested this idea. 48 participants received either a high or low working memory (WM) load and were instructed to respond to either a finger cue or spatial cue with a finger movement. Results indicate that occupying WM facilitates reaction times to finger cues while responses to simple spatial cues are unchanged. The findings suggest that imitation is indeed a dominant response and EF is needed to inhibit the spontaneous tendency to imitate.

Neural Dynamics of Constraint Relaxation and Problem Representation Changes in Single-Trial Insight Problem Solving: An fNIRS Study.
Behav Brain Res

Faculty of Human Sciences, Waseda University, 2‑579‑15 Mikajima, Tokorozawa, Saitama, Japan. Electronic address:
Insight problem solving involves overcoming an impasse when a solution seems unreachable, often experienced as an 'Aha!' moment. In such solving, shifting from an incorrect representation imposed by constraints to a correct representation through constraint relaxation is critical. Prior research compared brain activity when constraint relaxation and representation change occurred versus when they did not occur, but neural activity before and after such changes within trials has remained underexplored.

BackgroundTherapeutic plasma exchange (TPE) with albumin replacement has emerged as a potential treatment for Alzheimer's disease (AD). The AMBAR trial showed that TPE could slow cognitive and functional decline, along with changes in core and inflammatory biomarkers in cerebrospinal fluid.ObjectiveTo evaluate the safety and effectiveness of TPE in a real-world setting in Argentina.

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.
