Hair Cells

Hair Cells

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Accessory Structures of the Skin: Hair and Hair Follicles

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Azimuths and Bearings

Azimuths and Bearings

Azimuths and bearings are essential concepts in surveying, providing methods to express the direction of a line relative to a meridian. Azimuths refer to the clockwise angle measured from the north end of a reference meridian to the given line, ranging from zero to 360 degrees. This method gives a comprehensive directional reference within a full 360-degree circle, making it a straightforward way to communicate direction in various fields, including navigation, cartography, and...

Collar Bearings

Collar Bearings

Collar bearings are essential in various machines designed to support axial loads on rotating shafts. Depending on the specific application and requirements, they can be found with single or multiple collars.

Summary

Detecting drowsiness using electroencephalogram (EEG) from non-hair-bearing (NHB) scalp areas is as effective as traditional whole-scalp EEG. This finding supports convenient, real-world brain-computer interface (BCI) applications for drowsiness detection.

Background:

Drowsy driving is a significant global cause of fatal accidents.
Electroencephalogram (EEG)-based brain-computer interface (BCI) systems offer potential for drowsiness detection.
Acquiring high-quality EEG conveniently for long-term wear remains a challenge in real-world BCI applications.

Purpose of the Study:

To quantitatively evaluate the performance of drowsiness detection using EEG signals from non-hair-bearing (NHB) scalp areas.
To compare the efficacy of NHB EEG with traditional whole-scalp EEG for drowsiness detection.
To assess the practicality of NHB EEG for real-world BCI applications.

Main Methods:

Utilized cross-session validation to assess drowsiness detection performance.
Employed widely studied machine-learning classifiers for data analysis.
Acquired EEG data from non-hair-bearing (NHB) scalp regions.

Main Results:

No significant difference in drowsiness detection accuracy was found between NHB EEG and whole-scalp EEG across all subjects.
Informative drowsiness-related EEG features were accessible from NHB areas.
Offline results demonstrated comparable performance between the two EEG acquisition methods.

Conclusions:

Non-hair-bearing (NHB) EEG is an effective and practical alternative for drowsiness detection.
This approach overcomes limitations associated with hair interference in traditional EEG.
Findings support the development of convenient, real-world BCI applications, including drowsiness detection.
