What brain regions are activated when implicitly learning sequences? Folia and Petersson (2014) Results from classification task Saw both ungrammatical sequences during the scanning session Classify the sequences by pressing Yes or No. Only that region is activated?? What does it mean by NG > G? And why activation is shown up in that NG > G?

Another type of sequences: music Koelsch et al. (2005) Compare adults’ and children’s perception of music between musicians and non-musicians 3 groups: children with varying music training, adult musicians, adult non-musicians Stimuli: 72 chord sequences ending in either regular or irregular Task: sequence classification task (regular vs. irregular)

Another type of sequences: music Koelsch et al. (2005) Results BA 47 BA 47 Similar patterns to implicit learning of sequences BA 44, 45, 47

What brain regions are involved in Theory of Mind Young et al. (2010) 31 healthy adults Story reading task 2 by 2 design: Mental/Physical X Expected/Unexpected Why physical condition needed? If a region found to be active in Mental expected vs. Mental unexpected, is it just by chance or reflecting ToM?

What brain regions are involved in Theory of Mind Young et al. (2010) Behavioral results

What brain regions are involved in Theory of Mind Young et al. (2010) Defining regions of interest: Results from a previous study Bilateral temporo-parietal junction Results from story reading: Red: Mental > Physical Green: Unexpected > expected Yellow: Overlap of the above two

Does handwriting training facilitate literacy development?(James 2005) Left posterior fusiform gyrus 4-year-old children Two scanning sessions: 4 weeks apart (pre- and posttraining Two training methods: Hearing and saying the letter names Printing the letters (without saying) Handwriting training Visual-only training
