Cereb Cortex:气味是如何存储为长期记忆的

2018-01-02 佚名 中国生物技术网

德国波鸿鲁尔大学的神经系统科学家Christina Strauch博士和Denise Manahan-Vaugha教授研究了哪个大脑区域负责将气味存储为长期记忆。有些气味能够“嗅味生情”一下将你带到很多年前的记忆中。目前的研究表明,梨状皮质是嗅觉大脑的一个部分,与这些记忆的存储过程相关。然而,该机制仅仅在与其他大脑区域的交互中起作用。这项研究发表在《大脑皮层》期刊上。

德国波鸿鲁尔大学的神经系统科学家Christina Strauch博士和Denise Manahan-Vaugha教授研究了哪个大脑区域负责将气味存储为长期记忆。有些气味能够“嗅味生情”一下将你带到很多年前的记忆中。目前的研究表明,梨状皮质是嗅觉大脑的一个部分,与这些记忆的存储过程相关。然而,该机制仅仅在与其他大脑区域的交互中起作用。这项研究发表在《大脑皮层》期刊上。

Christina Strauch说:“我们知道,梨状皮质能够暂时存储嗅觉记忆。我们想要弄清楚它是否也适用于长期记忆存储。”

通过刺激产生的人工感觉

突触可塑性负责将记忆存储到大脑的记忆结构中:在这个过程中,神经元之间的通信被突触可塑性的过程改变,从而产生了记忆。Strauch和Manahan-Vaughan测试了小鼠的梨状皮质是否能够表达出突触可塑性,以及这种变化是否能够持续超过4个小时,这意味着长期记忆可能已经形成了。

科学家们利用电脉冲,在小鼠大脑中模拟将嗅觉编码为记忆的过程。他们采用了不同的刺激方案,这些方案的电脉冲频率和强度不同。他们已经知道,这些刺激方案能够对其他大脑区域(即海马体)产生长期作用,而这种长期作用负责形成长期记忆。令人惊讶的是,这些相同的方案没有在梨状皮质中以突触可塑性的形式形成长期记忆。

需要更高层的大脑区域信号

科学家们想要弄清楚,梨状皮质是否需要“指导”才能形成长期记忆。之后他们刺激了一个更高层的大脑区域——眼窝前额皮质,该区域负责辨别感觉经验。这次,对这个大脑区域的刺激使梨状皮质产生了科学家们所期待的变化。Strauch说:“我们的研究表明,梨状皮质事实上能够存储长期记忆。但是它需要眼窝前额皮质的指示,这是一个更高层的大脑区域,由它来指示梨状皮质将嗅觉存储为长期记忆。”

Science:人类的鼻子可以区分1万亿种气味?

由洛克菲勒大学(Rockefeller University)展开的一项最新研究显示,人类的鼻子可以区分 1 万亿种不同的气味组合,这比研究人员过去认为的要多许多。 尽管人类可以区分数百万种不同的颜色及几乎 50 万种不同的音调,但研究表明,人类只能区别大约 1 万种独特的气味,但这种说法还从来没有通过实验证据得以验证。与此同时,有些研究人员认为,由数百种不同受体所组成的人类嗅觉系统的分辨能力要

瑞典农业科学大学的Rickard Ignell和同事将研究发表在the Malaria Journal。 疟疾是由疟原虫所致的虫媒传染病,最常见的传播方式是通过按蚊叮咬感染。WHO指出,去年全球大约有2.14亿疟疾患者病例,约有438000人死于该病。撒哈拉以南非洲地区的疟疾疫情更为严重,2015年该地区的疟疾患者占全球疟疾患者的89%,占全球疟疾死亡人数的91%。 目前在高风险地区采取的的主要预

健康晴雨表,屎君有话讲

所谓一叶知秋,就是通过细微的现象可以看到整个形势的发展趋向与结果的意思,人体同样也通过细微的变化来昭示着健康的走势。这次小编就跟大家聊一聊便便那点事。可以将我们的身体内部比喻为便便工厂。食物吃进肚子,消化,被吸收,最后从肛门排出,这样便便就制成啦。一般来说2—3天大便1次,或每天排2—3次大便,大便柔软成形,都属正常范围。如果在原有排便习惯的基础上,排便次数增加,大便较稀,不成形,称之为腹泻。

PNAS:闻到的气味竟然不一样?“嗅觉指纹”独一无

我们每个人的鼻子大约有六百万个嗅觉感受器,约四百种不同的类型。这些受体的分布因人而异,所以每个人的嗅觉可能是独一无二的。近期发表在PNAS杂志上的一篇文章指出Weizmann研究所的科学家报告的方法可精确地描述一个人的嗅觉,他们称之为“嗅觉指纹”。 本研究的意义不仅仅局限于嗅觉范围,而且包括基于嗅觉指纹的大脑退行性疾病的早期诊断与匹配捐献器官的非侵入性测试。 该方法主要研究两种气味间是如何的相
