Note that the asterisk (*) indicates a history of seizure. Also, an “X” in the right hand columns indicates that the case was used in the study. The average PMI in the controls is only for the 6 cases with known PMI. The estimated average time in fixative prior to tissue processing is given for 7 known autism cases and 5 control cases.
