The principal component analysis (PCA) from the second MCSF test, 7 (CCI-injured animals, [28]) or 9 (cFPI animals) days post-injury. (A) PCA score plot showing the locations of the CCI and cFPI groups, indicating different behavioral patterns in the two groups; (B) PCA loading plot illustrating the MCSF variables that are included in the analysis. Variables located further away from the origin are most important for the model. CCI: Controlled cortical impact, n = 11 (from [28]); cFPI: Central fluid percussion injury, n = 16; CTRCI: Central circle; Dur: Duration; D/V: Duration per visit; Frq: Frequency; Lat: Latency; SLOPE E: Slope entrance; TOT ACTIVITY: Total activity in arena; TOTCORR: Total corridor entries.
