Timecourse of mirror and counter-mirror effects measured with transcranial magnetic stimulation.

Cavallo A, Heyes C, Becchio C, Bird G, Catmur C - Soc Cogn Affect Neurosci (2013)

Bottom Line: In addition, it is unclear whether mirror and counter-mirror effects follow the same timecourse.Experiment 2 demonstrated significant effects of counter-mirror sensorimotor training at all timepoints at which a mirror response was found in Experiment 1 (i.e. from 200 ms onward), indicating that mirror and counter-mirror responses follow the same timecourse.By suggesting similarly direct routes for mirror and counter-mirror responses, these results support the associative account of mirror neuron origins whereby mirror responses arise as a result of correlated sensorimotor experience during development.

nst085-F3: Experiment 2: mean ± s.e.m. response times during sensorimotor training.

Mentions: Mean RT was calculated for each block (Figure 3) and submitted to a repeated-measures ANOVA with block (1–12) as the within-subjects factor. A main effect of block was observed [F(11,187) = 6.477, P < 0.001], suggesting that counter-mirror performance improved during training. This conclusion was supported by a significant linear decrease in RT across blocks [F(1,17) = 11.981, P = 0.003] and by the finding that RT for the final block was significantly lower than for the first block [t(17) = 3.880, P = 0.001].Fig. 3
