This is a case report of an 81-year-old man who developed de novo bipolar disorder with ultrarapid cycling at the age of 80. Mood was self-rated daily over a period of ten weeks; in addition, polysomnographic and motor activity recordings were performed during a drug-free baseline period. Both depressive and hypomanic episodes had an average duration of(More)
A method based on wavelet entropy is presented for analysis of optically recorded action potentials to assess stability of the experiment. The action potentials are recorded using fluorescent voltage-sensitive dye di-4-ANEPPS by optical means. The acquired signals are preprocessed using averaging with filtered residue method and decomposed by continuous(More)
Early investigations on nocturnal penile tumescence (NPT) reported a close association with REM sleep; later, a less close coupling was observed under certain conditions e.g. in major depression. This supports the hypothesis that partly different mechanisms are involved in the regulation of both phenomena. In the present study, 45 male subjects suffering(More)
The paper presents a fibre optic sensor used for mapping electrical activity of the heart. The sensor is based on the use of a voltage-sensitive dye applied to an examined tissue. The intensity of the dye's fluorescent emission is proportional to the local electrical potential. The sensor is a part of an optical-electrical recording system used to collect(More)
