This study investigated the neural correlates of memory for human nonlinguistic emotional vocalizations as a function of individual differences in trait anxiety and depression. 20 healthy subjects (female; aged 18-30) free from neurological impairments or psychiatric illness underwent MRI scanning to obtain T1 structural images of their brain, and participated in a subsequent behavioral memory task outside the scanner. Volumetry of the hippocampus and amygdala was performed using a validated protocol. We found emotional vocalizations were better remembered than neutral ones, with performance for negative better than positive. Memory performance for emotional items was associated with hippocampal volume, with no association between memory and I amygdala volume detected. Differences in anxiety or depression had no influence on memory or volume. These results lay the groundwork for future functional neuroimaging work to investigate the neural correlates of memory, personality, and brain structure volume in healthy and clinical populations.
