| Abstract: | Influence of neurotoxic fragment of beta-amyloid peptide (25-35) on Helix lucorum behavioral plasticity (sensitization and food-aversion learning) was investigated. After beta-amyloid peptide (25-35) injection a significant reduction of behavioral long-term sensitization was observed. It was found, that beta-amyloid peptide (25-35) may interfere with associative learning and memory. Our results clearly demonstrate that beta-amyloid peptide (25-35) may play a significant role in behavioral plasticity by chronically eliminating certain underlying forms of synaptic plasticity. |
