Table 1.

The mean asymmetry quotient (AQ) and standard error (s.e.) is shown for each section of the sylvian fissure (SF) and superior temporal sulcus (STS) across taxonomic family

	Sylvian fissure			Superior temporal sulcus
	LSF (s.e.)	MSF (s.e.)	ISF (s.e.)	LSTS (s.e.)	MSTS (s.e.)	ISTS (s.e.)
Great apes	−0.011 (0.042)	−0.324 (0.034)	−0.082 (0.023)	−0.001 (0.049)	−0.006 (0.034)	−0.013 (0.022)
Old World monkeys	0.218 (0.058)	−0.370 (0.041)	−0.003 (0.021)	0.133 (0.042)	0.036 (0.024)	0.017 (0.020)
New World monkeys	−0.000 (0.107)	−0.268 (0.045)	−0.007 (0.023)	0.043 (0.118)	0.037 (0.055)	−0.009 (0.026)

The mean AQ values that are boldfaced indicate significant asymmetries (p < 0.05).
