In Synch but Not in Step: Circadian Clock Circuits Regulating Plasticity in Daily Rhythms [PDF]
The suprachiasmatic nucleus (SCN) is a network of neural oscillators that program daily rhythms in mammalian behavior and physiology. Over the last decade much has been learned about how SCN clock neurons coordinate together in time and space to form a ...

Elevated photic response is followed by a rapid decay and depressed state in ictogenic networks
The switch between non-seizure and seizure states involves profound alterations in network excitability and synchrony. Both increased and decreased excitability may underlie the state transitions, as shown in epilepsy patients and animal models. Inspired

Influence of sinusoidally modulated visual stimuli at extremely low frequency range on the human EEG Activity [PDF]
The purpose of this study was to investigate whether sinusoidally modulated visual stimuli at extremely low frequencies (ELF) of 50, 16.66, 13, 10, 8.33 and 4Hz could influence the changes in EEG activity in 33 human subjects.

Mechanisms of Photosensitive Epilepsies
Intermittent photic stimulation was performed in 21 photosensitive epileptic patients and the relation of the photoparoxysmal response (PPR) to the epilepsy syndrome was determined in a study at the National Epilepsy Center, Shizuoka Higashi Hospital ...

Uniform decrease of alpha-global field power induced by intermittent photic stimulation of healthy subjects [PDF]
Nineteen-channel EEGs were recorded from the scalp surface of 30 healthy subjects (16 males and 14 females, mean age: 34 years, SD: 11.7 years) at rest and under trains of intermittent photic stimulation (IPS) at rates of 5, 10 and 20 Hz.
