  1. Positive correlations ipsilateral: low metabolism is associated with a low behavioural value. Positive correlations contralateral: high metabolism is associated with a high behavioural value. Negative correlations ipsilateral: low metabolism is associated with a high behavioural value. Negative correlations contralateral: high metabolism is associated with a low behavioural value. *p < 0.05; **p < 0.01
