[Title] Iroise Dumontheil Ian Apperly Sarah-Jayne Blakemore Institute of Cognitive Neuroscience, UCL UCL Neural substrates of online perspective taking and its development during adolescence
UCL Dumontheil, Apperly, Blakemore, Dev Science (in press) Is the social brain network (mPFC, STS, temporal poles) recruited during online perspective taking? Or are brain regions supporting mental rotations (parietal & premotor cortex) recruited ? How does the neural substrates for this task changes during development ? * Blakemore Nature Reviews Neuroscience 2008
[Title] UCL - 5 x 6s trials/block : Female (filler, exp), Male (filler, exp) randomised in the block = 30s block + 1s instruction (Directors/No-directors) - Session: 5 x Directors (31s), 5 x No-directors (31s), 5 x Rest (20s) = 650. - Debriefing/questionnaire at the end regarding strategy used to do the task. Subjects Females, right handed, 18 adolescents: 11-17y; 12 adults: 20-30y Move the bottom cube left Directors blocks No-directors blocks Male voice: Move the purple block Female voice: Move the white block Male voice: Move the white block Female voice: Move the purple block F M
[Investigators & Affiliations] UCL Females, right handed Adolescents: 18 x 11-16y, adults: 12 x 20-30y Three functional runs: 4 x 650min Two structural scans: Joes Flash sequence – 2 x 5.5min Block design Analysis : Directors vs No-directors Directors vs No-directors x Age Brain coverage: 35 slices, TR=3s, TE=50ms, 3x3x3mm
