Effects of cerebral ischemia in mice lacking DNA methyltransferase 1 in post-mitotic neurons.

abstract：:Using functional magnetic resonance imaging (fMRI), we investigated whether the response of auditory and visual cortex was modulated by attending selectively to either heard or seen numbers presented simultaneously. Alternating attention between modalities modulated fMRI signal within the corresponding sensory cortex....
