FIG 3. A, Change in activation of left hemispheric auditory and language relevant cortex across 2 background noise conditions (12 sections = 6 Hz; 4 sections = 2 Hz). Note significantly increased activation (P < .05) within the STG, MTG/STS, and IFG subregions to text listening in the presence of more rapid acoustic scanner noise production, in men (n = 6) compared with women (n = 6). Nonsignificant increased activation is also seen within the AG, SMG, and PFC of men. There is no change in activation to the more rapid noise rate in women.
B, Activated pixels in auditory and language cortex in response to text listening with 2 underlying background acoustic scanner noise conditions (2 Hz and 6 Hz). Left hemispheric activation in response to text listening in a woman is shown to be similar between the 2 underlying background acoustic noise conditions (upper images). Left hemispheric activation to text listening in a man is significantly increased by increasing the rate of data acquisition and associated increased rate of background acoustic scanner noise (lower images).
