Abstract:
s Objective: To identify neural correlates for the recognition of familiar verbal voices by measuring regional blood oxygen level-dependent (BOLD) signal by functional magnetic resonance imaging (fMRI). Methods:Thirteen Chinese health male subjects (mean age 26.1 years, SD= 2.9years) participated in the study. All subjects were right-handed and Han nationality. The subjects listened to familiar (subjects' friends) and unfamiliar voices when functional scanning. Functional data were acquired using a 1.5T MRI (GE Systems, USA), and were analyzed using statistical parametric mapping 99 (SPM99). A fixed-effects model was employed to assess the difference in BOLD response between 'familiarity' and 'unfamiliarity' conditions (P
