Minisymposium
513. Measuring the Dynamics of Neural Circuits in Awake, Behaving Humans: Functional Connectivity Analyses of fMRI Data
Tue, Oct 16, 8:30 – 11:00 AM

Tue, Oct 16, 9:55 – 10:15 AM
513.06 – Tracking information flow across participants using granger causality

1. mirror neurons and info transfer
2. tracking info across brains with granger
3. tracking info WITHIN brains with granger

———–
Keysers et al 2003
1) premotor cortex electrode recordings
10% also resonds when sees hears or knows

observed ACTIONS
—-> translated
Observer’s motor representation

see Hasson et al TICS 2012

—use FUNCTIONAL CONNECTIVITY to go from brain to brain
—used GAME of charades – in the scanner
see Schippers et al PLOSone 2009 PNSA 2012
90% accurate
exchange roles
now get brain activity of gesturer and observer

handerwerker et al 2004 Neuroimage – looked at hemodynamic function in 4 areas across 20 people

schippers, renken and keysers neuroimage 2011
