Electrophysiological dynamic brain connectivity during symbolic magnitude comparison in children with different mathematics achievement levels.

abstract：:We examined the effect of long-term potentiation (LTP) on paired-pulse responses across varied stimulus intensities and interstimulus intervals (ISIs), at ascending synapses from the intermediate and ventral hippocampus to the medial prefrontal cortex in urethane-anesthetized rats. LTP significantly shifted the median...
