[Effects of weak low-frequency electromagnetic field on sleep structure during daytime sleep].

Objective: To test the hypothesis that weak electromagnetic fields of low frequencies (0.5-26 Hz) could affect daytime sleep features and structure.

Material And Methods: Parameters of daytime sleep continuity were compared in the study with counterbalanced control/exposition (40 min exposure to electromagnetic field at 1 Hz/0.

[Application of the method of one-day learning in a Morris water maze to analyse the effects of sleep deprivation on memory trace recall 24 hours later, after learning].

The proposed model of a one-day spatial learning is of interest in research of how sleep influences the hippocamp-dependent memory consolidation. We have studied the influence of a one-day total sleep deprivation on spatial memory consolidation in hooded rats after a one-day learning in the Morris water maze according to Feldman et al. [2010] protocol.
