Published: Jan. 21, 2025

Drowsiness detection is crucial for ensuring the safety of individuals engaged in high-risk activities. Numerous studies have explored drowsiness techniques based on EEG signals, but these typically been validated computers, which limits their portability. In this paper, we introduce design and implementation a technique utilizing executed Zynq7020 System Chip (SoC) as part Pynq-Z2 module. This approach more suitable portable applications. We implemented Discrete Wavelet Transform (DWT) feature extraction functions intellectual property (IP) cores, while other run ARM processor Zynq7020.

Advanced Intervention Effects of Pulsed and Steady Transcranial Photobiomodulation on Sleep, Mood, and EEG Signal Regulation

Journal of Biophotonics, Journal Year: 2025, Volume and Issue: unknown

Published: March 18, 2025

ABSTRACT Background Transcranial photobiomodulation (tPBM) enhances cognitive and emotional states. We compared continuous‐wave (CW) pulsed‐wave (PW) tPBM effects on 24 healthy males. Method Participants received 630 nm at 95 mW/cm 2 for 10 min: Sham, CW, or PW (500 Hz). Outcomes were assessed using the Karolinska Sleepiness Scale (KSS) (for measuring sleepiness), State‐Trait Anxiety Inventory (STAI) assessing anxiety), Visual Analog (VAS) stress), Beck Depression Inventory‐II (BDI‐II) evaluating depressive symptoms), 32‐channel EEG baseline, treatment, rest phases. Results Paired t ‐tests showed significantly improved sleepiness, anxiety, stress, depression scores post‐intervention ( p < 0.05). ANOVA analyses indicated increased Alpha Gamma band power versus baseline Conclusion may improve outcomes modulate brain activity, offering therapeutic insights.
