研究人员发现影响政治参与强度的大脑回路

2025-04-07 15:50 by 异形:悲伤之海

芝加哥西北大学的研究团队研究了有和没有脑损伤的越战老兵,这是越战头部损伤研究的一部分,这是一个长期项目,研究与战斗有关的脑损伤对神经行为的影响。在 2008 年至 2012 年间,神经科学家对这些退伍军人进行了广泛的行为问题,评估了他们的政治信仰和情感强度的各个方面——大约在他们受伤 40 到 45 年后。参与者报告了他们当前的政治行为和他们受伤前的政治行为的回忆。这项研究包括 124 名头部有穿透性创伤的美国男性退伍军人和 35 名没有持续脑损伤的战斗暴露的对照组参与者。在提问之前,科学家们已经使用损伤网络映射技术绘制了退伍军人的大脑损伤图,这是一种神经成像技术,可以识别与特定损伤相连的更广泛的大脑回路。然后,他们根据行为数据分析了特定的大脑网络是否与政治信仰有关。研究人员称,“我们没有发现与自由或保守意识形态有关的大脑网络,但我们确定了影响政治参与强度的回路,这表明,情绪等因素决定了人们如何表达已有的政治信仰,而不是决定意识形态本身。”

How to Buy Bitcoin?

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
