Activities in portions of cortex representing different locations are highly correlated.

	FEF	IPS	V3A	V1-V4
FEF	0.554	0.544	0.523	0.517
IPS	0.544	0.569	0.501	0.573

Interhemispheric regional correlations in preparatory activity between regions modulating with the direction of the cue. Bold values indicate correlations between homologous portions of the same region (e.g., L FEF and R FEF) in opposite hemispheres. All other values indicate the average of two interhemispheric correlations (e.g., L FEF with R IPS and R FEF with L IPS). Note that homologous pairings are usually more highly correlated than nonhomologous pairings.
