Figure 3: Plasticity in the superior temporal cortex induced by sign language and by auditory deprivation with age as a covariate.
From: Dissociating cognitive and sensory neural plasticity in human superior temporal cortex
Results presented in this figure correspond to comparisons between the same three groups described in the main text, but with larger number of participants. Deaf Signers: N=15; Deaf Oral: N=10; Hearing Non-Signers: N=18. Images from each individual were taken to a second level analysis of variance for group comparison. The effect of auditory deprivation was evaluated with the conjunction of T-contrasts [DS>HN] and [DO>HN]; that of sign language with the conjunction [DS>DO] and [DS>HN]. Results were overlaid on three-dimensional representations of the brain (left) or sagittal slices (right). Images are displayed at a threshold of P<0.005 (uncorrected) and a spatial threshold of 20 voxels, but activations are discussed only if they reached corrected significance (P<0.05, FWE corrected) at cluster or single voxel level. Coordinates are in MNI space. All values±s.e.m.
