A simple electronic and computer system for automatic spindle detection.

The authors present a new system for the automatic detection of sleep spindles. The electronic and computer analysis are described and a comparison between automatic and visual analysis, performed by two independent readers, was carried out with the aim of evaluating the reliability of the system. Results are discussed and compared with those of different systems already described.

[Eye movements in sleep: towards a model].

The study of the REM-process by means of the oculomotor frequencies has shown that it is a stochastic point process. Therefore, the techniques utilized to quantify the time-dependency of this process were used. The structure of occurrence of REM's quantified by transition probability matrixes evidenced a two-state first order semi-Markov process.
