ALT Audiovisualization of functional near-infrared spectroscopy (fNIRS) resting-state HbO data from the prefrontal cortex in an adult male. The fNIRS probe configuration includes 22 long-distance channels (SD=30 mm) and 2 short-separation channels (the latter are not displayed here and are used solely to regress superficial physiology). The data were filtered to isolate the functional connectivity band, ranging between 0.009 and 0.08 Hz, and interpolated onto a 256x128 pixel grid, covering an area of 105x52 mm. Only positive relative changes of HbO are shown. This presentation's original duration of 361 seconds has been compressed to 61 seconds. Tools used: pyanthem, fluidsynth, ffmpeg, miniconda, Python 3.7, MATLAB, HOMER3, and custom scripts. Reference: Thibodeaux, D. N. et al. (2024). Audiovisualization of real-time neuroimaging data.
