海马体中的突触可塑性被认为在发育过程中神经元回路的完善和成熟大脑的学习中起着至关重要的作用。海马体CA1区的突触具有强大的长期增强(LTP)能力,而海马体CA2区辐射层的突触尤其抵抗这种变化。虽然我们还没有完全理解这种可塑性抵抗背后的机制,但在CA2中高度表达的一些基因和细胞外基质成分似乎在啮齿动物大脑的可塑性和发育中起着分子制动器的作用。奇怪的是,几种富含ca2的分子的发育特征暗示了海马体中仍未定义的可塑性关键窗口。
Synaptic plasticity in the hippocampus is thought to play a vital role in both the refinement of neuronal circuits during development and in learning in the mature brain. Synapses in hippocampal area CA1 are known for a robust capacity for long-term potentiation (LTP), whereas synapses in the stratum radiatum of hippocampal area CA2 are particularly resistant to such changes. Although we have yet to fully understand the mechanisms behind this resistance to plasticity, a number of genes and extracellular matrix components highly expressed in CA2 appear to function as molecular brakes on plasticity and develop postnatally in the rodent brain. Curiously, the developmental profile of several CA2-enriched molecules is suggestive of a still undefined critical window of plasticity in the hippocampus.
