Introduction: Currently, type 1 diabetes mellitus (T1DM) is treated with insulin and a high carbohydrate diet. In literature, there are studies indicating that low carbohydrate diets may be beneficial in reducing hypoglycemic episodes as well as the need for insulin. Previously, we reported a case of a 19-year-old T1DM patient who was successfully...

In the human sleep literature there is much controversy regarding the existence and the characteristics of hippocampal rhythmic slow activity (RSA). Generally the human RSA is believed to occur in short bursts of theta activity.

Recent evidence suggests that the sleep-dependent consolidation of declarative memories relies on the non-rapid eye movement (NREM) rather than the rapid eye movement (REM) phase of sleep.

Sleep and the hippocampus are two issues which were both related to the problem of memory processes. Based on the available experimental data it can be assumed that sleep has a favourable influence on the process of memory consolidation, and the hippocampus has a crucial role in this effect. Here we aim to unravel the neural activity patterns of the human mediotemporal structures during different sleep-waking states. We aim to provide electrophysiological data in order to support model building.
