How the Nonextensivity Parameter Affects Energy Fluctuations

In this article, the effect of the nonextensivity parameter on the energy fluctuations of nonextensive systems is studied in two different versions of the Tsallis statistical mechanics. Once a general expression has been reported for the energy fluctuations in the second version (Tsallis work in 1988), the energy fluctuations of an ideal gas and a harmonic oscillator are studied in the second a...

How Aging Affects Sleep-Dependent Memory Consolidation?

Memories are not stored as they were initially encoded but rather undergo a gradual reorganization process, termed memory consolidation. Numerous data indicate that sleep plays a major role in this process, notably due to the specific neurochemical environment and the electrophysiological activity observed during the night. Two putative, probably not exclusive, models ("hippocampo-neocortical d...

How sleep deprivation affects gene expression in the brain: a review of recent findings.

The identification of the molecular correlates of sleep and wakefulness is essential to understand the restorative processes occurring during sleep, the cellular mechanisms underlying sleep regulation, and the functional consequences of sleep loss. To determine what molecular changes occur in the brain during the sleep-waking cycle and after sleep deprivation, our laboratory is performing a sys...

How Personality Affects Literacy Development

Sleep in brain development.

With the discovery of rapid eye movement (REM) sleep, sleep was no longer considered a homogeneous state of passive rest for the brain. On the contrary, sleep, and especially REM sleep, appeared as an active condition of intense cerebral activity. The fact that we get large amounts of sleep in early life suggested that sleep may play a role in brain maturation. This idea has been investigated f...
