The possibility of a link between medial axes (hereafter called symmetries) and figure salience has recently been proposed [Vision Res. 38 (1998) 2323; Vision Res. 38 (1998) 2429]. In this paper we investigated the characteristics of transient visual evoked potentials (VEPs) associated with stimulus figures designed to have different symmetries. Significant trends were observed for VEP components N1 (160-190 ms) and P2 (220-250 ms). N1 and P2 had shorter peak latencies for stimuli with greater symmetry peak amplitudes. © 2001 Elsevier Science Ltd. All rights reserved.
