Amygdala volume and social anxiety symptom severity: Does segmentation technique matter?

The amygdala factors prominently in neurobiological models of social anxiety (SA), yet amygdala volume findings regarding SA have been inconsistent and largely focused on case-control characterization. One source of discrepant findings could be variability in volumetric techniques. Therefore, we compared amygdala volumes derived via an automated technique (Freesurfer) against a manually corrected approach, also involving Freesurfer.

Hippocampal volume and auditory attention on a verbal memory task with adult survivors of pediatric brain tumor.

Objective: We examined the nature of verbal memory deficits and the possible hippocampal underpinnings in long-term adult survivors of childhood brain tumor.

Method: 35 survivors (M = 24.10 ± 4.

Reading skill in adult survivors of childhood brain tumor: a theory-based neurocognitive model.

Objective: This study investigated the relationship between word reading and white matter (WM) integrity within a neuroanatomical-based reading system comparing adult survivors of childhood brain tumors and controls. It was predicted that the association between WM integrity and word reading would be mediated by processing speed, and this indirect effect would be moderated by group.

Method: Thirty-seven adult survivors of childhood brain tumor and typically developing adults participated (age M = 24.
