The human photosensitive epilepsy model for clinical proof‐of‐principle trials of novel antiseizure medications. 1. Use of the EEG in drug development and characteristics of the model

Epilepsia, EarlyView.
Abstract Clinical development of novel antiseizure medications (ASMs) would benefit from an early proof‐of‐principle (POP) model. The photosensitivity model, which uses the photoparoxysmal electroencephalography (EEG) response (PPR) as a surrogate for seizures, is currently the only human model that allows POP trials of investigational compounds after ...

Abnormal EEG Responses to Photic Stimulation in Schizophrenic Patients [PDF]

Schizophrenia Bulletin, 1990
Numerous studies have differentiated schizophrenic patients and normal controls in electroencephalography (EEG) spectral patterns recorded at rest. We replicated the resting EEG spectral differences between these groups and observed significant differences in periodic photic stimuli on the EEG spectra. Drug-free schizophrenic male patients (n = 8, mean

Closed-loop photic stimulation using EEG [PDF]

, 2020
Accumulating evidence indicates that neural oscillations play a central role in brain function, organising and modulating brain activity in response to both bottom-up exogenous stimuli and top-down endogenous dynamics.

Effects of irradiance and stimulus duration on early gene expression (Fos) in the suprachiasmatic nucleus: temporal summation and reciprocity. [PDF]

, 2000
The daily behavioral, physiological, and hormonal rhythms in mammals are regulated by an endogenous circadian clock located in the suprachiasmatic nucleus (SCN) and are synchronized by the natural 24 hr light/dark cycle.

Familial SYNGAP1 variants define the boundaries of a complex neurodevelopmental disorder with epilepsy

Epilepsia, EarlyView.
Abstract Objective SYNGAP1‐related disorders are common neurodevelopmental conditions characterized by autism spectrum disorder, developmental delay, intellectual disability, and a range of generalized seizure types. Disease‐causing variants in SYNGAP1 typically occur de novo. This study aims to characterize inherited cases of SYNGAP1‐related disorders.

A post hoc analysis of migraine‐associated symptoms from the phase 3 randomized, double‐blind, sham‐controlled Trial of External trigeminal nerve stimulation for the Acute treatment of Migraine (TEAM) study

Headache: The Journal of Head and Face Pain, Volume 65, Issue 5, Page 779-790, May 2025.
Abstract Background The Trial of External trigeminal nerve stimulation (eTNS) for the Acute treatment of Migraine (TEAM) study demonstrated that eTNS use during active migraine resulted in significantly higher rates of resolution of migraine‐associated most bothersome symptom (MBS) compared to sham.

Subdural electrode recording of generalized photoepileptic responses [PDF]

, 2014
We evaluated the spatiotemporal distribution of photic driving (PDR), photoparoxysmal (PPR), and photoconvulsive (PCR) responses recorded by intracranial electrodes (ic-EEG) in a patient with generalized photosensitivity and right frontal lobe cortical ...

Timing mismatches, carryover effects, and the role of neuroendocrine mechanisms in determining birds' responses to environmental change

Journal of Neuroendocrinology, EarlyView.
Neuroendocrine mechanisms that synchronize annual cycle stages influence the likelihood of (1) timing mismatches between stages and environmental conditions, and (2) carryover effects among stages. We suggest that there is a trade‐off such that neuroendocrine mechanisms that reduce timing mismatches may inherently increase the likelihood of carryover ...

Profile of photic driving in electroencephalography records at Mohammad Hoesin Hospital Palembang [PDF]

, 2019
Photic driving (PD) is a normal electroencephalography phenomenon in the parietooccipital region  during intermittent photic stimulation (IPS). The PD response is an indicator that is sensitive to age, brain maturity, certain abnormalities, changes in ...
