Table 1. Quantitative Analysis of AAV–FMRP Transduction in Cingulate Cortex at the end of the Long Arm (PND 61).

Animal #	FMRP+ cells/mm2	NeuN+/FMRP+ cells/mm2	% of neuronal transduction
1	1714±470	1588±403	94±2
2	2154±734	2097±731	96±2
3	2042±666	2003±656	98±1

The cells were counted in three consecutive coronal 25-μm thick sections (100 μm apart) of the cingulate cortex from each brain (total of nine sections from three mice) and reported as the average number of cells per square millimeter±SEM.
