21. Reelin-dependent strengthening of long-term potentiation is caused by ApoER2 interaction with NMDA receptor. 22. D 5 receptors may be required for long-term potentiation at the synapse between hippocampal formation. 23. High-frequency stimulation causes an increase in release called post-tetanic potentiation ( Kandel 2003 ). 24. When potentiation is sustained by long-term use, neuroadaptations occur which result in decreased GABAergic response. 25. In light of this they propose a new long term potentiation model for grapheme-color projector synesthesia. 26. The pituitary-adrenocortical and pituitary-gonadal systems are thought to affect readiness or potentiation for anger responding. 27. Some IEGs such as zif268 and Arc have been implicated in learning and memory and long-term potentiation . 28. This potentiation is abolished in cells expressing the R43Q mutant subunit instead of the wild-type ? subunit. 29. Calretinin has an important role as a modulator of neuronal excitability including the induction of long-term potentiation . 30. Sleep deprivation may affect memory by interfering with neuroplasticity as measured by long-term potentiation in the hippocampus.
