Analysis and classification of sleep stages is a fundamental part of basic sleep research. Rat sleep stages are scored based on electrocorticographic (ECoG) signals recorded from electrodes implanted epidurally and electromyographic (EMG) signals from the temporalis or nuchal muscle. An automated sleep scoring system was developed using a support vector(More)
The aim of this study is to identify a possible function of Active Sleep (AS), also known as Rapid Eye Movement Sleep (REM) in humans, as a protective state during early Central Nervous System (CNS) development. Previous research suggest pharmacological agents that inhibit high levels of neuronal activity in the CNS (e.g., benzodiazepines, ethanol, and(More)
OBJECTIVE This paper attempts to delineate an appropriate methodology for research into cardiovascular diseases (CVD) in the context of the Australian Indigenous population. DESIGN Our argument proceeds in three main stages of critical analysis of the appropriate literature. First we demonstrate the extremely complex aetiology of CVD and also argue that,(More)
A body of literature is developing which identifies an additional stage of sleep in rats, cats and mice. Intermediate stage (IS) sleep is a measurable sleep stage that is maintained by the hyperpolarization of GABA(A) containing thalamocortical neurons. The present study attempts to clarify inconsistencies within the sleep spindle literature. Most notably,(More)
