Response types and their criteria

PMC			SPL
Memory-active	Memory > math	Math-selective	Math > memory
	Memory > baseline		[Math >2 SDs * memory]
			Math > baseline
Math-deactive	Math < memory	Math-active	Math > Memory
	Math < baseline		[Math <2 SDs * memory]
			Math > baseline
			Memory > baseline

Comparisons in square brackets (i.e., “[…]”) represent numerical (rather than statistical) criteria, while those without brackets denote significant differences based on nonparametric permutation tests. The math and memory HFB time courses for each response type are visually displayed in Figure 1.
