Abstract

We demonstrate that a colour RGB-CCD camera can be used to map haemoglobin changes of the exposed cortex following cortical activation and spreading depression in rats. We examine its performance by a comparison with narrow bandpass spectroscopy and evaluation of the extinction spectra of haemoglobin based on condition number analysis.
