Allie Ward与Michael Yassa博士讨论了记忆的方方面面,包括记忆的形成、存储位置、遗忘的原因以及影响记忆的因素。Yassa博士解释了记忆并非单一类型,不同类型的记忆储存在大脑的不同区域,例如海马体在将短期记忆转化为长期记忆中起着关键作用,但记忆并非只储存在海马体中。他还探讨了神经递质(如多巴胺)和激素(如皮质醇和雌激素)对记忆的影响,以及年龄和性别差异对记忆的影响。此外,他们还讨论了诸如“舌尖现象”、闪光灯记忆、联觉和童年遗忘等现象,以及压力、睡眠和激素水平等因素如何影响记忆。Yassa博士强调了记忆的动态性和可塑性,以及记忆并非为了回忆过去,而是为了指导未来的决策。他还指出,虽然一些重大事件的记忆可能非常清晰,但其细节的准确性可能随着时间推移而下降。最后,他们还讨论了潜意识记忆和创伤性记忆等复杂问题。 Michael Yassa博士详细解释了记忆的神经生物学机制,包括记忆的细胞基础(突触可塑性)、神经递质(多巴胺)和激素(皮质醇、雌激素)的作用,以及不同脑区在不同类型记忆中的作用(例如,海马体在情景记忆中的作用)。他强调了大脑的可塑性,以及不同感官输入如何影响记忆的形成和存储。他还讨论了与记忆相关的常见现象,例如“舌尖现象”和闪光灯记忆,并解释了这些现象背后的神经机制。此外,他还探讨了年龄、性别、压力和睡眠等因素对记忆的影响,以及童年遗忘和创伤性记忆等复杂问题。Yassa博士还介绍了高度优越的自传体记忆(HSAM)这一罕见现象,并指出其记忆机制尚不清楚。

Deep Dive

Shownotes Transcript

How are memories made? Where are they stored? Where do they go? What was I just talking about? Neurobiologist, professor, researcher, and Director of UC Irvine’s Center for the Neurobiology of Learning and Memory, Dr. Michael Yassa, joins us for a two-parter deep diving into our memories. Get to know the cells that run your life while he also busts flim-flam, and talks about movie myths, aging and memory loss, childbirth amnesia, what happens when you cram for a test, hormones and memory, that thing where you can’t remember a word, how to let go of the past, and more. Next week, we’ll follow up with your Patreon questions about Alzeihmer’s, remembering people’s names, neurodivergence, dementia, collective misremembering, and so much more. Commit it to memory.
