Repetition Suppression Study of non-Mirroring Mirror Neurons Geoff Bird, Hannah Widmann, Clare Press, Caroline Catmur, James Kilner, Celia Heyes

Mirror Neurons and RS Pairs of Action Stimuli – Obs/Exe and Exe/Obs Cross modal RS for repeat vs non-repeat trials. 96 repetitions, 43mins, 10Ss, 16 slices on IFG. Kilner et al 2009, JoN

Alternative RS Design Unimodal (exe) study of action planning. 19 Ss, 4sec action execution event, 4sec rest. 36 trials (~5min) in total.

Analysis – Full-Factorial ANOVA using SPM8. Contrast repeat vs non-repeat trials after long and short delays. Check to see whether obs/exe or exe/obs makes a difference. 32-channel head coil. Potentially reduce coverage for faster scanning (IFG?) Custom-built response apparatus – borrowed from James Kilner. 2secs
