Memory required (bytes) = [(8C + 2A) x S x T] + 1 MB*
C = Number of calculation channelsA = Number of analog channelsS = Sample rate (samples/second)T = Recording time (acquisition length)* 1 MB = memory required to store file informationJournals, events, and other information are variable and will also require more disk space. Once analog channels are filtered or otherwise transformed, the required amount of storage will increase to 8 bytes per sample, identical to calculation channels. It is not possible to perform any transformations for acquisitions where converting analog channels to floating point will exceed 2 GB.
Refer to the software guide available under the program Help menu for setup and analysis guidelines when working with large files.
The STMEPM Programmable Stimulation System for E-Prime allows a user to interface the STMISOLA Stimulator with E-Prime to control the stimulus frequency and stimulus intensity for real-time stimulus delivery changes based on a subject’s responses. It is also possible to hardcode the stimulus intensity levels in the presentation so that predefined stimulus levels are delivered […]
View AllThe new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
