Effect of diethyl pyrocarbonate modification of benzodiazepine receptors on [3H]Ro 15-4513 binding.

abstract：:Maternal separation (MS) is known to affect hippocampal function such as learning and memory, yet the molecular mechanism remains unknown. We hypothesized that these impairments are attributed to abnormities of neural circuit formation by MS, and focused on brain-derived neurotrophic factor (BDNF) as key factor becaus...
