The neurochemical basis of photic entrainment of the circadian pacemaker [PDF]

Circadian rhythmicity in mammals is controlled by the action of a light-entrainable hypothalamus, in association with two cell clusters known as the supra chiasmatic nuclei (SCN).

Photic stimulation: standardization of the method based on european consensus [PDF]

, 2008
INTRODUCTION: Although intermittent photic stimulation (IPS) is a widespread and routinely used procedure in EEG laboratories, only relatively recently has a standardization of the IPS method been proposed.

Epilepsy in dentatorubral–pallidoluysian atrophy: A systematic review and meta‐analysis

Epilepsia, EarlyView.
Summary of key clinical and electrophysiological characteristics of DRPLA‐related epilepsy from a systematic review and meta‐analysis of 1,191 patients. DRPLA patients with epilepsy showed earlier disease onset, longer CAG repeat expansion, and a tendency toward paternal inheritance. EEG findings frequently included photoparoxysmal responses.

Comparability of Functional MRI Response in Young and Old During Inhibition [PDF]

, 2004
When using fMRI to study age-related cognitive changes, it is important to establish the integrity of the hemodynamic response because, potentially, it can be affected by age and disease.

Long‐term sub‐erythemal UVB exposure does not impact circadian rhythms in mice under standard and rotating shift light conditions

Photochemistry and Photobiology, EarlyView.
Circadian disruption is a potential carcinogen, but the impact of environmental carcinogens on circadian rhythms is unclear. Here we evaluated the impact of chronic UVB exposure with environmental‐ and genetic‐induced circadian disruption on mouse rhythmic locomotor activity and clock gene expression. Created in BioRender.

Bioelectric signal analysis and measurement [PDF]

Nonstationary time series techniques are used to analyze EEG signals for the estimation of alertness. A time varying order is extracted in sequential time series measurement of these data and strategies are devised for obtaining optimal representation of

Electroencephalography in the Diagnosis of Genetic Generalized Epilepsy Syndromes

Frontiers in Neurology, 2017
Genetic generalized epilepsy (GGE) consists of several syndromes diagnosed and classified on the basis of clinical features and electroencephalographic (EEG) abnormalities. The main EEG feature of GGE is bilateral, synchronous, symmetric, and generalized
