Brain-derived neurotrophic factor overexpression induces precocious critical period in mouse visual cortex.
Brain-derived neurotrophic factor (BDNF) is a candidate molecule for regulating activity-dependent synaptic plasticity on the grounds of its expression pattern in developing visual cortex and that of its receptor, trkB (Castr¿n et al., 1992; Bozzi et al., 1995; Schoups et al., 1995; Cabelli et al., 1996), as well as the modulation of these patterns by activity (Castr¿n et al., 1992; Bozzi et al...
متن کاملAction of brain-derived neurotrophic factor on function and morphology of visual cortical neurons
Brain-derived neurotrophic factor (BDNF) is known to play a role in experience-dependent 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. Such acute actions of BDNF suggested to be mediated mainly through presynaptic mechanisms. A chronic application of BDNF to the visual cor...

Dekan Summary BDNF (brain-derived neurotrophic factor) plays an important role in neuronal survival, growth and maintenance of several neuronal systems, serves as neurotransmitter modulator and participates in plasticity important for learning and memory. BDNF is widely expressed in the CNS, beginning early in development and extending throughout life. In the mammalian brain, it is most abundan...
متن کاملBrain-derived neurotrophic factor alters the synaptic modification threshold in visual cortex.
The effects of brain-derived neurotrophic factor (BDNF) were investigated on synaptic transmission and two forms of activity-dependent synaptic plasticity, long-term potentiation (LTP) and long-term depression (LTD), in visual cortex slices prepared from young (P21 -28) rats. The slices treated for 2-5 h in BDNF showed no difference from control slices when a 'strong' tetanus was used (theta-bu...
