A Moving Target Detection Model Inspired by Spatio-Temporal Information Accumulation of Avian Tectal Neurons

Mathematics, 2023
Moving target detection in cluttered backgrounds is always considered a challenging problem for artificial visual systems, but it is an innate instinct of many animal species, especially the avian.

Hemodynamics for Brain-Computer Interfaces [PDF]

IEEE Signal Processing Magazine, 2008
This article brings together the various elements that constitute the signal processing challenges presented by a hemodynamics-driven functional near-infrared spectroscopy (fNIRS) based brain-computer interface (BCI). We discuss the use of optically derived measures of cortical hemodynamics as control signals for next generation BCIs.

Brain-Computer Interfaces in Medicine [PDF]

Mayo Clinic Proceedings, 2012
Brain-computer interfaces (BCIs) acquire brain signals, analyze them, and translate them into commands that are relayed to output devices that carry out desired actions. BCIs do not use normal neuromuscular output pathways. The main goal of BCI is to replace or restore useful function to people disabled by neuromuscular disorders such as amyotrophic ...

MINERVA: A CubeSat for demonstrating DNA damage mitigation against space radiation in C. elegans by using genetic modification

Heliyon, 2022
The ideas of deep-space human exploration, interplanetary travel, and space civilizations are becoming a reality. However, numerous hindrances remain standing in the way of accomplishing these feats, one of which is space ionizing radiation.

Improving AR-SSVEP Recognition Accuracy Under High Ambient Brightness Through Iterative Learning

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Augmented reality-based brain-computer interface (AR-BCI) system is one of the important ways to promote BCI technology outside of the laboratory due to its portability and mobility, but its performance in real-world scenarios has not been fully studied.

Brain Computer Interfaces for inclusion [PDF]

Proceedings of the 1st Augmented Human International Conference, 2010
In this paper, we describe an intelligent graphical user interface (IGUI) and a User Application Interface (UAI) tailored to Brain Computer Interface (BCI) interaction, designed for people with severe communication needs. The IGUI has three components; a two way interface for communication with BCI2000 concerning user events and event handling; an ...

Elevated Gamma Connectivity in Nidopallium Caudolaterale of Pigeons during Spatial Path Adjustment

Animals, 2022
Previous studies showed that spatial navigation depends on a local network including multiple brain regions with strong interactions. However, it is still not fully understood whether and how the neural patterns in avian nidopallium caudolaterale (NCL ...

Long and Short Durations of Binaural Beats Differently Affect Relaxation: A Study of HRV and BRUMS

IEEE Access, 2023
Objective: We aimed to identify parasympathetic and emotional alterations, as indicated by the heart rate variability (HRV) and Brunel mood scale (BRUMS), after long-term exposure to theta binaural beats (BB) for 10 minutes daily.

The strathclyde brain computer interface [PDF]

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
Brain-computer interfaces (BCI) offer potential for individuals with a variety of motor and sensory disabilities to control their environment, communicate, and control mobility aids. However, the key to BCI usability rests in being able to extract relevant time varying signals that can be classified into usable commands in real time. This paper reports

An EEG-based attention recognition method: fusion of time domain, frequency domain, and non-linear dynamics features

Frontiers in Neuroscience, 2023
IntroductionAttention is a complex cognitive function of human brain that plays a vital role in our daily lives. Electroencephalogram (EEG) is used to measure and analyze attention due to its high temporal resolution.
