科学领域:
- 神经科学是一个神经科学.
- 内分泌学 在内分泌学.
- 放射学 放射学是一门学科.
背景情况:
- 甲状腺功能低下症与认知和情绪失调有关,但神经病理学的基础尚不清楚.
- 研究甲状腺功能低下症中大脑变化的研究对于了解其对心理健康的影响至关重要.
研究的目的:
- 在亚临床甲状腺功能障碍症 (SCH) 和明显甲状腺功能障碍症 (OH) 中描述海马子子子域体积和功能连接性 (FC) 变化.

Role of Hippocampus in Memory
252
The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...

Long-term Depression
2.5K
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.
