The Timing of Reward-Seeking Action Tracks Visually-Cued Theta Oscillations in Primary Visual Cortex [PDF]

open access: yes, 2017
An emerging body of work challenges the view that primary visual cortex (V1) represents the visual world faithfully. Theta oscillations in the local field potential (LFP) of V1 have been found to convey temporal expectations and, specifically, to express

Absence Seizures as a Feature of Juvenile Myoclonic Epilepsy in Rhodesian Ridgeback Dogs [PDF]

open access: yes, 2018
Myoclonic epilepsy in Rhodesian Ridgeback (RR) dogs is characterized by myoclonic seizures occurring mainly during relaxation periods, a juvenile age of onset and generalized tonic-clonic seizures in one-third of patients. An 8-month-old female intact RR

Preliminary trial of photic stimulation for premenstrual syndrome

open access: yesJournal of Obstetrics and Gynaecology, 1997
In an open study 17 women with confirmed, severe and long-standing premenstrual syndrome used photic stimulation with a flickering red light, every day for up to four menstrual cycles. At the end of treatment prospectively recorded median luteal symptom scores were reduced by 76% (95% confidence interval 54-93, P < 0.001), with clinically and ...

Uniform decrease of alpha-global field power induced by intermittent photic stimulation of healthy subjects

open access: yesBrazilian Journal of Medical and Biological Research, 2002
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.

Topographic aspects of photic driving in the electroencephalogram of children and adolescents

open access: yesBrazilian Journal of Medical and Biological Research, 2004
The electroencephalogram amplitude spectra at 11 fixed frequencies of intermittent photic stimulation of 3 to 24 Hz were combined into driving "profiles" for 14 scalp points in 8 male and 7 female normal subjects aged 9 to 17 years.

³¹P magnetization transfer magnetic resonance spectroscopy: assessing the activation induced change in cerebral ATP metabolic rates at 3 T [PDF]

open access: yes, 2017
Purpose: In vivo ³¹P MRS magnetization transfer (MT) provides a direct measure of neuronal activity at the metabolic level. This work aims to use functional ³¹P MRS-MT to investigate the change in cerebral ATP metabolic rates in healthy adults upon ...
