Influence of phosphatidylserine on cognitive performance and cortical activity after induced stress
TLDR
It is found that chronic supplementation of phosphatidylserine significantly decreases Beta-1 power in right hemispheric frontal brain regions (F8; P < 0.05) before and after induced stress.Abstract:
The aim of this study was to investigate the effect of phosphatidylserine (PS) on cognition and cortical activity after mental stress. After familiarization, 16 healthy subjects completed cognitive tasks after induced stress in a test–re-test design (T1 and T2). Directly after T1, subjects were assigned double-blind to either PS or placebo groups followed by T2 after 42 days. At T1 and T2, cortical activity was measured at baseline and immediately after stress with cognitive tasks using electro-encephalography (EEG). EEG was recorded at 17 electrode positions and fast Fourier transforms (FFT) determined power at Theta, Alpha-1, Alpha-2, Beta-1 and Beta-2. Statistics were calculated using ANOVA (group × trial × time). The main finding of the study was that chronic supplementation of phosphatidylserine significantly decreases Beta-1 power in right hemispheric frontal brain regions (F8; P < 0.05) before and after induced stress. The results for Beta-1 power in the PS group were connected to a more re...read more

TL;DR: Two main approaches are proposed: the combination of features extracted from electroencephalogram (EEG) signal by different extraction methods, and the use of stacked sequential learning to incorporate predicted information from nearby sleep stages in the final classifier.

The effect of phosphatidylserine administration on memory and symptoms of attention‐deficit hyperactivity disorder: a randomised, double‐blind, placebo‐controlled clinical trial
TL;DR: PS supplementation significantly improved ADHD symptoms and short-term auditory memory in children and might be a safe and natural nutritional strategy for improving mental performance in young children suffering from ADHD.

Omega-3 fatty acids administered in phosphatidylserine improved certain aspects of high chronic stress in men.
TL;DR: It is concluded that subgroups characterized by high chronic stress and/or a dysfunctional response of the hypothalamus-pituitary-adrenal axis may profit from omega-3 PS supplementation.

TL;DR: This article examines two iVR mediums: the Cave Automated Virtual Environment (CAVE) and the head-mounted display (HMD) and compares the room-scale CAVE and HTC Vive Pro HMD with a custom in-house exercise game that was designed such that user experiences were as consistent as possible between both systems.

TL;DR: The main thrust of Electroencephalography is to preserve the sound basis of classic EEG recording and reading and, on the other hand, to present the newest developments for future EEG/neurophysiology research, especially in view of the highest brain functions as mentioned in this paper.

High-resolution EEG mapping of cortical activation related to working memory: effects of task difficulty, type of processing, and practice.
TL;DR: The results serve to dissociate the effects of task difficulty and practice, to differentiate the involvement of posterior cortex in spatial versus verbal tasks, to localize frontal midline theta to the anteromedial cortex, and to demonstrate the feasibility of using anatomical MRIs to remove the blurring effect of the skull and scalp from the ongoing EEG.
