Obstructive sleep apnea (OSA) is a sleep-related breathing disorder characterized by obstructions of the upper airway during sleep, resulting in repetitive breathing pauses accompanied by oxygen desaturation and arousal from sleep. OSA can be successfully treated with continuous positive airway pressure (CPAP), weight loss, positional therapy, oral appliances, hypoglossal nerve stimulation, and surgical procedures. It has been observed that untreated OSA is related to chronic disorders including hypertension, arrhythmias, congestive heart failure, coronary heart disease, diabetes mellitus, hyperlipidemia, stroke, depression, and cognitive decline. Event-related potentials (ERPs) is the procedure that has been widely used for evaluating cognitive brain functions. Using auditory event-related potentials (P300), this study aimed to examine the effect of CPAP therapy on cognitive functions in patients with moderate and severe OSA. The results of the study showed improvement in P300 latency and amplitude after 3 months of CPAP therapy, indicating a positive effect of CPAP therapy in the prevention of cognitive decline in patients with OSA.

Objective: To describe the cortical evoked potentials in response to radiofrequency stimulation (RFEPs) in human volunteers.

Methods: Seventeen healthy volunteers participated in an experimental session in which radiofrequency (RF) and electrical (ES) stimulation were applied to the dorsum of the hands and feet. EEG was recorded to evaluate evoked responses for each stimulus modality and stimulation site.

Common and distinct ERP responses to violations of two different types of politeness maxims during sentence comprehension.

An ERP experiment was conducted to investigate the common and distinct neurocognitive mechanisms underlying the on-line processing of two types of politeness maxims (self-depreciation and other-elevation) and the individual differences during sentence reading. Electroencephalograms were recorded while participants read sentences containing pragmatically appropriate or inappropriate honorific or humble terms. When collapsing all participants' data, inappropriate humble and honorific terms elicited N400 and P600 effects, respectively, which could reflect semantic processing costs and rechecking processes, respectively.

Preschool-onset major depressive disorder (PO-MDD) is an impairing pediatric mental health disorder that impacts children as young as three years old. There is limited work dedicated to uncovering neural measures of this early childhood disorder which could be leveraged to further understand both treatment responsiveness and future depression risk. Event-related potentials (ERPs) such as the P300 have been employed extensively in adult populations to examine depression-related deficits in cognitive and motivational systems.

Overactive bladder (OAB) is a prevalent chronic condition affecting approximately 12% of adults, with incidence increasing with age. While pharmacological and behavioural therapies are standard treatments, their efficacy is often limited by side effects and poor adherence. This study aimed to compare the therapeutic effects of precision magnetic stimulation guided by motor-evoked potential with general magnetic therapy in patients with OAB.

Background: Deficits in emotion recognition have been shown to be closely related to social-cognitive functioning in schizophrenic. This study aimed to investigate the event-related potential (ERP) characteristics of social perception in schizophrenia patients and to explore the neural mechanisms underlying these abnormal cognitive processes related to social perception.

Methods: Participants included 33 schizophrenia patients and 35 healthy controls (HCs).
