During attempts to examine the phosphorylation status of extracellular signal-regulated kinase (ERK) in cerebral cortex immunohistochemically, we determined whether deep anesthesia for euthanasia disturbs the phosphorylation status of ERK, because the anesthesia might influence activity-dependent phosphorylation of ERK. We compared effects of short (2 and 5(More)
BACKGROUND Experience during early postnatal development plays an important role in the refinement of specific neural connections in the brain. In the mammalian visual system, altered visual experiences induce plastic adaptation of visual cortical responses and guide rearrangements of afferent axons from the lateral geniculate nucleus.

Monocular deprivation (MD) during the critical period reduces the visual cortical response to the deprived eye and causes the geniculocortical axons serving the deprived eye to retract. When MD is combined with a pharmacological inhibition of the visual cortex, the cortical neurons weaken their response to an open eye and the input axons serving the open(More)
