From: Level of M1 GABAB predicts micro offline consolidation of motor learning during wakefulness

Relationship between baseline GABA concentrations and micro-offline learning consolidation when 95% of total learning occurred. In the left panel, the short intracortical inhibition corresponding to GABAA modulation is reported; in the right panel, the long intracortical inhibition corresponds to GABAB neurotransmitter modulation.
