SBRG.s2s This offline script calculates baroreceptor reflex sensitivity based on spontaneous fluctuations in blood pressure. MergeFiles.s2s /SplitFiles.s2s These utility scripts allow you to splice auto-saved data files end to end before further analysis and to split data related to different animals into separate data files.
every 24 hr.) in order to achieve virtually continuous recording over days or weeks. Data can be auto-saved to a new file at regular intervals (e.g. Results are recorded continuously or according to a user-defined schedule, e.g. Data from up to 8 animals can be analysed on- or off-line. HRBP8b.s2s derives systolic, diastolic and mean blood pressure, heart rate and respiratory rate from each blood pressure trace. The scripts are suitable for use with a range of laboratory animals and can record data from up to 8 animals simultaneously when used together with telemetry systems. This family of Spike2 v7 scripts and sampling configurations allows you to perform long-term recordings of blood pressure, heart rate and sympathetic activity and to analyse baroreceptor reflexes and heart rate variability. Send your bug reports and ideas for further development to Analysis Resp Phases These scripts require Spike2 version 8.09 or higher.

The price that you pay for excellent signal source separation is loss of amplitude information, - the results are normalised. Importantly, the method can also separate mains hum and sources of electrical interference from signals of physiological origin. ICA is also applicable in physiological recording situations where multiple electrodes are used to record underlying signals, for example, scalp EEG electrodes, intra-cranial multi-electrode EEG recordings, surface EMG recordings or electrode arrays in a tissue culture. For example, ICA offers a solution to the classical "Cocktail party problem": Can one disentangle individual voices from a conversational hubbub? ICA can do this provided that the sound was recorded from several different positions using multiple microphones. It is very useful for extracting the underlying signals from a group of recordings where each individual channel is an unknown mixture of signals from several underlying generators. ICA refers to a group of mathematical methods for separating sampled waveforms into statistically independent components.
