Abstract

Brain-derived neurotrophic factor (BDNF) is known to play a role in experiencedependent plasticity of the developing visual cortex. For example, BDNF acutely enhances long-term potentiation and blocks long-term depression in the visual cortex of young rats [1–3]. Such acute actions of BDNF are suggested to be mediated mainly through presynaptic mechanisms. A chronic application of BDNF to the visual cortex of kittens is known to expand ocular dominance columns in the cortex [4]. Recently we have demonstrated that BDNF is transferred from presynaptic axon terminals to postsynaptic neurons in an activity-dependent manner, suggesting the possibility that BDNF also has chronic postsynaptic actions [5]. To test this possibility, we carried out two types of experiments.
