This allowed the researchers to observe Jupiter for almost two hours on Aug. 16 and 17, 2008, a record duration, according to the observing team.
By altering sampling frequency and maintaining a constant recording duration, the length of the time series was also manipulated.
To assure the quality and reliability of the recording the following criteria were imposed: (1) a minimum recording duration of 120 s, (2) stable simple spike amplitude, (3) no clear signs of tissue damage in a circle with 400 µm radius, around the recording site.
The repetition frequency of the click stimulus signal was 11 times/min, superimposed 2048 times with a 10 ms recording duration.
We also show that recording duration is a critical parameter, with large improvements in repeatability apparent when using ten minute, compared to five minute recordings.
Although we do not require more than 2-3 hofrecordingording time to accurately assess rhythms in the firing patterns in GnRH neurons, we believe the maximum recording duration of a single cell could be between 6 and 8 hours based on our estimations of brain slice viability.
The temporal measures include Fleiss' kappa, a modified kappa (to normalize differences in recording duration), positive (seizure) and negative (nonseizure) agreement rate.
We also sorted all previous experiments with these recording conditions and TH immunocytochemical identification by recording duration to determine if there was a relationship between recording duration and percent TH.
The best recording duration time is determined to 10 min with a higher accuracy of large than 99%.
The recording duration is measured in minutes.
