Article Abstract
Purpose The study aimed to assess the value of event-related potentials (ERP) of executive functions in distinguishing between attention deficit hyperactivity disorder (ADHD) and ADHD combined with autism spectrum disorder (ADHD&ASD). Methods This retrospective analysis included 204 participants divided into three groups: ADHD&ASD (64/204), ADHD (70/204), and typical development (TD) (70/204). Neuropsychological tests, including the Digit Span Test, Behavior Rating Inventory of Executive Function (BRIEF), Trail Making Test at its Chinese equivalent version, the Shape Trail Test (STT), and the Stroop Color Word Interference Test, were compared across groups. ERP measures, such as latency and amplitude at the frontal zone (Fz), central zone (Cz), and parietal zone (Pz), along with reaction times and target stimulus hits using an oddball paradigm, were analyzed. Post-hoc analyses and receiver operating characteristic (ROC) curves identified key indicators for distinguishing ADHD from ADHD&ASD. Results Significant differences were found in ERP and BRIEF indicators (P < 0.001), as well as selected TMT and Stroop parameters (P < 0.05) across the groups. The ADHD&ASD group exhibited notably higher Fz, Cz, and Pz latencies, interference times, and reaction times compared to the ADHD group (P < 0.05). With the exception of word meaning interference time, the area under ROC curves (AUC) of the remaining five indicators exceeds 0.8. Particularly noteworthy is the combined ROC curve of Fz latency and average reaction time, which demonstrated a sensitivity, specificity, and AUC of 88.68%, 97.14%, and 0.938 (95%CI: 0.885-0.990, P < 0.001), respectively. Conclusion ERP measurements using oddball paradigms hold strong potential for distinguishing ADHD from ADHD&ASD, enabling the development of more targeted treatment approaches through precise neurophysiological markers.

The lateral prefrontal cortex (LPFC) serves as a critical hub for higher-order cognitive and executive functions in the human brain, coordinating brain networks whose disruption has been implicated in many neurological and psychiatric disorders. While transcranial brain stimulation treatments often target the LPFC, our current understanding of connectivity profiles guiding these interventions based on electrophysiology remains limited. Here, we present a high-resolution probabilistic map of bidirectional effective connectivity between the LPFC and widespread cortical and subcortical regions.

The existence of free will has been called into question by Benjamin Libet's seminal experiment, who argued that our conscious decision is preceded by an unconscious decision reflected in the readiness potential (RP). Alternatively, it has been argue that the RP rather reflects a decision process in which different signals accumulate until they reach the intention threshold, at which point an agent experience their intention simultaneously. This raises the question what type of signal is accumulated given that no external information is provided.

Introduction: We aimed to clarify the effects of an active touch intervention using different textures on corticospinal excitability.
Methods: A total of 30 healthy individuals participated in the active touch intervention. Two tactile stimuli were used for intervention: smooth (silk) and rough (hessian) stimuli.

This study sought to enhance visual acuity assessment using steady-state visual evoked potentials (SSVEPs) through subject-specific training methods. SSVEPs were elicited from eleven subjects using the vertical sinusoidal gratings at six various spatial frequency steps, and then the classical approach of Oz single-channel, the spatial filtering method of canonical correlation analysis (CCA), and five subject-specific training methods, i.e.

Background: Precisely timed brain stimulation, such as phase-locked deep brain stimulation (PLDBS), offers a promising approach to modulating dysfunctional neural networks by enhancing or suppressing specific oscillations. However, its clinical application has been hindered by the lack of user-friendly systems and the challenge of real-time phase estimation amid stimulation artifacts.
Material And Method: In this work, we developed a clinically translatable PLDBS framework that enables real-time, cycle-by-cycle stimulation using standard amplifiers and a computer-in-the-loop system.
