Figure 1

Total RNA Gel images from the Bioanalyser (Agilent). Representative total RNA samples of varying quality, as assessed objectively by RIN and by subjective assessment. Selected corresponding pre- and post-chip variable assessments are also shown. Samples identified as outliers on post-chip quality control measures but not excluded are labelled (*); outliers excluded from expression analysis are labelled (**). Sample from case with prolonged agonal state (†). Sample not run on arrays due to poor quality total RNA (‡). n.d. is value not determined. CB, cerebellum; CN, caudate nucleus; MC, motor cortex.
