- 肥胖问题研究研究
背景情况:
- 肥胖与抵抗美味食物的困难有关,可能是由于对饮食行为的抑制控制受损.
- 加强对食物相关记忆的抑制控制是肥胖管理的一个建议策略.
- 右背侧前额皮质 (dlPFC) 对于调节奖励驱动的冲动至关重要,但其对肥胖患者食物记忆控制的调节尚未得到充分研究.
研究的目的:
- 研究将食物思考/不思考 (TNT) 训练与针对正确dlPFC的高清超直流刺激 (HD-tDCS) 结合在一起的影响.
- 评估超重/肥胖个体对与食物有关的记忆的抑制控制的影响.
主要方法:
- 使用食物思考/不思考 (TNT) 的范式.
- 雇佣的HD-tDCS针对的是正确的dlPFC.
- 在健康体重和超重/肥胖群体中评估了与食物相关的记忆的抑制控制.
主要成果:
- 阳极刺激在健康体重和超重/肥胖群体中显著改善了记忆抑制.
- 超重/肥胖个体表现出更大的早期减少记忆入侵,这表明极刺激的潜在益处更大.

01:14Role of Cerebellum and Prefrontal Cortex in Memory
1.0K
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
552
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
