Photos of the Brazilian actigraph ACT10 ("Tempatilumi")
<p>Photos of the Brazilian actigraph ACT10 produced by the company CE Brasil, also called “Tempatilumi” by researchers.</p> <p>The actigraph details can be found on the company's website (defunct) through the following link: <a href="https://web.archive.org/web/20071218222809/http://www.cebrasil.com.br/CE/Biomedicos.htm">https://web.archive.org/web/20071218222809/http://www.cebrasil.com.br/CE/Biomedicos.htm</a>.</p> <p>"The ACT10 Actimeter is an electronic device that is attached to a person's body, like a wristwatch, capable of recording body temperature, movement intensity, ambient lighting and time of events, in order to assist in the acquisition of data on biomedical experiments. All of this information is stored in a non-volatile FLASH-type memory, together with time from a real-time clock.<br> The system also has a programmable alarm according to the research needs."</p>
A non-parametric model-free analysis of actigraphic recordings of acute insomnia patients
Both parametric and non-parametric approaches to time series analysis have advantages and disadvantages. Parametric methods, although powerful and widely used, can yield inconsistent results due to the oversimplification of the observed phenomena, they require the setting of arbitrary constants for their creation and refinement, and, although these constants relate to assumptions about the observed systems, it can lead to erroneous results when treating a very complex problem with a sizable list of unknowns. Their non-parametric counterparts, instead, are more widely applicable but present a higher detrimental sensitivity to noise and low density in the data. For the case of approximately periodic phenomena, such as human actigraphic time series, parametric methods are widely used and concepts such as acrophase are staple in chronobiology; in this work we present a non-parametric method of analysis of actigraphic time series from insomniac patients and healthy age-matched controls, the method is fully data-driven, reproduces previous results in the context of sleep-onset delay and, crucially, extends the concept of acrophase not only to circadian but also for ultradian spectral components.
