{"text":"Phase angle vs. frequency. (left) Phase angle of impedance with linear regression line. (right) To provide an easier comparison, phase angles have been levelled with respect to the linear regression line that passes through each set of data. The addition of cells causes the peaks to shift to lower frequencies and decrease in amplitude.","sourcedb":"PMC","sourceid":"2992534","divid":8,"section":"Caption-Figure 4","source_url":"http://www.ncbi.nlm.nih.gov/pmc/2992534"}
