Effect of photic stimulation on acetylcholine release from cat cerebral cortex [PDF]

, 1972
Cortical release of acetylcholine was assayed using the leech muscle preparation in cats with transected brainstems. Both spontaneous and elicited somatosensory and visual cortical release of acetylcholine were measured, photic stimuli being directed ...

A validation study for a consumer-grade auditory-visual stimulation device

Current Directions in Biomedical Engineering, 2022
Self-care and improving one’s well-being has been growing rapidly in recent years for manifold reasons (e.g. higher workload, corona pandemic). Consumer-grade noninvasive stimulation devices are therefore on the rise to counteract the occurrence of mood ...

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.

Burst-suppression is reactive to photic stimulation in comatose children with acquired brain injury

, 2016
Objective: Burst-suppression is an electroencephalographic pattern observed during coma. In individuals without known brain pathologies undergoing deep general anesthesia, somatosensory stimulation transiently increases the occurrence of bursts.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Effect of 10 and 20 Hz photic stimulation on stress and temperature of the fingers

, 2012
This paper evaluates the effect of photic stimulation at frequencies of 10 and 20 Hz on lowering stress for therapeutic purposes. This study also measures the increase of the temperature in the extremities when the person is receiving this stimulation as

Biometric Authentication from Photic Stimulated EEG Records

Applied Artificial Intelligence, 2021
Studies on brain biometrics have shown that electroencephalogram (EEG) signals encourage more secure authentication. The uniqueness, persistence, universality and robustness of EEG signals against fraud attacks offer potential for highly secure biometric

Unveiling sleep disturbances in KCNB1‐related disorders: Insights from a cohort of 78 individuals

Epilepsia Open, EarlyView.
Abstract Objectives Sleep disturbances are frequent comorbidities in epilepsies and developmental encephalopathies. This study aimed to characterize sleep abnormalities in individuals with KCNB1‐related disorders, focusing on their prevalence, clinical manifestations, and impact on daily functioning.
