Changes in Alpha Frequency and Power of the Electroencephalogram during Volatile-Based General Anesthesia

open access: yesFrontiers in Systems Neuroscience, 2017
Oscillations in the electroencephalogram (EEG) at the alpha frequency (8–12 Hz) are thought to be ubiquitous during surgical anesthesia, but the details of how this oscillation responds to ongoing changes in volatile anesthetic concentration have not ...

Comment on Kobrick and Cahoon's “Correspondence of Brightness Enhancement to Cortical Alpha Rhythm”

open access: yes, 1968
The note comments on Kobrick and Cahoon's apparent misunderstanding of what brightness enhancement is, how it is related to the alpha rhythm, and upon their seemingly oversimplified view of the relation of neurophysiological records and sensory ...

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Unified theory of alpha, mu, and tau rhythms via eigenmodes of brain activity

open access: yesFrontiers in Computational Neuroscience
A compact description of the frequency structure and topography of human alpha-band rhythms is obtained by use of the first four brain activity eigenmodes previously derived from corticothalamic neural field theory.

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Design criteria for an EEG Alpha Rhythm Monitor [PDF]

open access: yes, 1977
Design criteria for construction of a device for monitoring the frequency of the alpha rhythm of the human EEG are presented in this thesis. Power spectral analysis is implemented on a minicomputer system and its limitations are illustrated. The need for

Modulation of the Parieto-Occipital Alpha Rhythm during Object Detection

open access: yes, 1997
Changes in the human neuromagnetic alpha rhythm were monitored during an object detection task to study the effects of visual shape processing on the parieto-occipital activity.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
