She does not have multiplications memorised, so I'd guess that basal ganglia is where there are problems, at least. She has problems remembering which hand is the right and the left one and, when given a fraction, is denominator above or below the line, and similar issues. (So do I, for that matter.) Does this help with the classification? | |
