Progressive myoclonus epilepsy in Down syndrome with Alzheimer's disease: An 11‐year longitudinal study and proposed diagnostic red flags

open access: yesEpilepsia Open, Volume 11, Issue 4, Page 1200-1213, August 2026.
Abstract Objective Individuals with Down syndrome (DS) face an ultra‐high risk of Alzheimer's disease (AD). Within this continuum, Progressive Myoclonus Epilepsy (PME) has emerged as a marker of advanced neurodegeneration. Building on our 2014 characterization of this syndrome, we aimed to define its long‐term natural history and pathological substrate.

Spectral and Bispectral Analysis of the EEG Rhythms in Basal Conditions and During Photic Stimulation [PDF]

open access: yes, 2004
The aim of the present study is the quantification of the relationships and the phase coupling among spectral peaks in the EEG signal at different sites of the scalp. 10 normal subjects underwent the study.

Spectral F-Test power evaluation in the EEG during intermittent photic stimulaton Avaliação do teste-F espectral do EEG durante fotoestimulação intermitente

open access: yesArquivos de Neuro-Psiquiatria, 2006
Intermittent photic stimulation (IPS) is an important functional test, which can induce the photic driving in the electroencephalogram (EEG). It is capable of enhancing latent oscillation’s manifestations not present in the resting EEG.

Relative entropy as a biomarker for vagus nerve stimulation response in epilepsy: Insights from intracerebral electroencephalography

open access: yesEpilepsia Open, Volume 11, Issue 4, Page 1343-1353, August 2026.
Abstract Objective This study aims to analyze differences in pre‐implantation invasive electroencephalographic (IEEG) data between vagus nerve stimulation (VNS) responders (>50% seizure reduction) and VNS nonresponders (<50% seizure reduction). Methods We retrospectively identified 19 patients with drug‐resistant focal epilepsy who underwent IEEG ...

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 710-718, August 2026.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

Some Observations on EEG Response to Photic Flicker Stimulation [PDF]

open access: yes, 1961
By applying a combined method of crosscorrelation and frequency analysis to EEG tracings, the average response patterns to photic flicker stimulation with a frequency in the alpha wave range were sorted out, even when the application of the frequency ...

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

open access: yesJournal of Applied Entomology, Volume 150, Issue 7, Page 914-922, August 2026.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.
