Note: All entries, except for the number of cells, are means ± SD. *P < 0.05, 2-tailed t-tests with Bonferroni–Holm correction, for comparisons against mean values calculated across the entire data epochs. **P < 0.05, 2-tailed t-tests with Bonferroni–Holm correction, for comparisons against corresponding values in normal monkeys. Brackets behind the total number of cells contain the number of cells from individual monkeys.
