Abstract/OtherAbstract:
During a critical period, unilateral retinal lesions induce rapid axonal sprouting of intact axons into denervated territories within the collicular visual layers. We investigated the effect of caffeine, a non-selective A(1) and A(2a) antagonist, upon the lesion-induced plasticity of retinotectal axons. Pigmented rats submitted to a temporal retinal lesion received either caffeine (30mg/kg, ip) or saline treatment. The anterograde tracing revealed that caffeine treatment during the critical period resulted in a clear reduction on the sprouting of ipsilateral fibers but to an amplification of the plasticity after PND21, thus revealing opposite effects depending on the developmental time window.
