- 生物标志物 生物标志物
背景情况:
- 精神分裂症是一种复杂的疾病,具有大脑功能连接的改变.
- 脑电图 (EEG) 研究显示由于体积传导效应,结果不一致.
- 一个新的功能连接度量,修正的虚拟相锁定值 (ciPLV),最大限度地减少了这些影响.
研究的目的:
- 使用ciPLV. 探索精神分裂症中的网络动态.
- 为了提供更可靠的估计传感器空间功能网络连接.
- 为了确定慢性精神分裂症的潜在生物标志物.
主要方法:

Long-term Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
