很抱歉，但我无法直接访问外部链接或使用特定的应用程序如 JinaReader 来抓取和分析内容。不过，我可以提供一些一般性的指导。 如果你想要使用 JinaReader 或类似工具来抓取和分析网页内容，并且该内容不是中文，需要翻译成中文，以下是一个大致的步骤： 1. **抓取内容**： - 使用 JinaReader 或类似的工具，配置它以爬取你提供的链接（https://brainhack.vercel.app/fus）。 - 确保配置中包含了提取文本内容的功能。 2. **内容分析**： - 使用文本分析工具来处理抓取到的内容。这可能包括提取关键词、分析情感、识别主题等。 3. **翻译内容**： - 如果内容不是中文，可以使用在线翻译服务（如 Google 翻译、百度翻译等）将内容翻译成中文。 - 可以手动复制粘贴内容到翻译工具，或者编写脚本自动化翻译过程。 4. **总结内容**： - 使用翻译后的中文内容进行总结。 - 这可能需要阅读和理解内容，然后提取主要观点和信息，形成简短的总结。 以下是一个简化的例子，说明如何使用 Python 和一些常用的库来完成这个过程： ```python import requests from bs4 import BeautifulSoup from googletrans import Translator # 请求网页内容 url = "https://brainhack.vercel.app/fus" response = requests.get(url) soup = BeautifulSoup(response.content, 'html.parser') # 提取文本内容 text = soup.get_text() # 翻译内容 translator = Translator() translated_text = translator.translate(text, src='auto', dest='zh-cn').text # 总结内容（这里只是一个简单的例子，实际总结可能需要更复杂的逻辑） summary = "由于没有访问网页内容的具体细节，以下是一个假设的总结：..." print(summary)请注意，上述代码是一个简化的示例，实际应用中可能需要处理更多细节，例如处理JavaScript渲染的内容、优化文本提取和翻译的准确性等。此外，由于我无法访问实际的网页内容，无法提供具体的翻译和总结。
## Post by: lawrenceyan ### Comments: **sfink**: Surely this is easily solved with time-reversed acoustics. Just stab a transmitter into the brain with an ice pick to the point you want to measure, and pick up the signal at lots of locations around the skull. Now you have both a mapping from an input signal (the reverse of the signal you picked up) that you can send to precisely target that point, and you know it looks like after it comes out from that point (the original signal you picked up).<p>Now you can tell exactly what is going on and the person is thinking! Specifically it'll be either: (1) "oh my god, I have an ice pick in my brain" or (2) nothing, because they have an ice pick in their brain. > **sfink**: 当然，这很容易用时间反转声学来解决。只需用冰镐将发射器刺入大脑，到达你想要测量的点，并在头骨周围的许多位置拾取信号。现在，你既有一个来自输入信号的映射（与你拾取的信号相反），你可以发送它来精确地瞄准那个点，你也知道它从那个点出来后的样子（你拾取的原始信号）<p> 现在你可以准确地说出发生了什么，这个人在想什么！具体而言；将是：（1）"；哦，天哪，我脑子里有个冰镐"；或者（2）什么都没有，因为他们脑子里有个冰镐。 **dr_dshiv**: “The thing that nobody tells you is that you can buy a real human skull online (shoutout to skullsunlimited.com). We did that, and then CT scanned it.”<p>This is an A+ > **dr_dshiv**: “没有人告诉你的是，你可以在网上买到一个真正的人类头骨（向skullsunlimited.com大喊）。我们做到了，然后CT扫描了它。”<p>这是一个a+ **tbenst**: This is fun, and the modeling is cool for sure, but it's well known that ultrasound can be used with surgical precision in the human brain.<p>Focused ultrasound is already used for non-invasive neuromodulation. Raag Airan's lab at Stanford does this for example using ultrasound uncaging.<p><a href="https://www.frontiersin.org/journals/neuroscience/articles/10.3389/fnins.2020.00675/full" rel="nofollow">https://www.frontiersin.org/journals/neuroscience/articles/1...</a><p><a href="https://www.sciencedirect.com/science/article/pii/S0896627318309504" rel="nofollow">https://www.sciencedirect.com/science/article/pii/S089662731...</a><p>Also see the work by Urvi Vyas, eg<p><a href="https://pubmed.ncbi.nlm.nih.gov/27587047/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/27587047/</a><p>I don't mean to discount the cool imaging-related reconstruction of a point spread function, but rather to say that ultrasound attenuation through the skull an soft tissue has already been well characterized and it's not a surprise that it is viable to pass through. > **tbenst**: 这很有趣，建模当然很酷，但它；众所周知，超声波可以精确地用于人脑手术<p> 聚焦超声已经用于非侵入性神经调控。Raag Airan；斯坦福大学的实验室就是这样做的，例如使用超声波去套管<p> <a href=“https:”www.frontiersin.org“”期刊“”神经科学“”文章“”10.3389“fnins.202.00675”full“rel=”nofollow“>https:”/；www.frontiersin.org；期刊；神经科学；文章#x2F；1…</a><p><a href=“https://www.sciencedirect.com”科学文章“S089662731839504”rel=“nofollow”>https:/；www.sciencedirect.com；科学；文章#x2F；pii；S089662731…</a><p>另请参阅Urvi Vyas的作品，例如<p><a href=“https:/；pubmed.ncbi.nlm.nih.gov�&#rel=“nofollow”>https:/；pubmed.ncbi.nlm.nih.gov；27587047</a> <p>我不知道；这并不意味着低估了点扩散函数的冷成像相关重建，而是说通过颅骨和软组织的超声衰减已经得到了很好的表征；通过并不奇怪。 **_Microft**: Also check out their other post: <a href="https://brainhack.vercel.app/ae" rel="nofollow">https://brainhack.vercel.app/ae</a><p>They are planning to locally change the electrical conductivity of brain tissue by focused ultrasound, modulate that with at few hundred kHz and do a lock-in (EEG) measurement to deduce electrical activity at that spot on the scale of 1mm. Pretty wild if that actually works. > **_Microft**: 另请查看他们的另一篇帖子：<a href=“https:/；brainhack.vercel.app/'ae”rel=“nofollow”>https:/；brainhack.vercel.app；ae</a><p>他们计划通过聚焦超声局部改变脑组织的电导率，以几百kHz的频率对其进行调制，并进行锁定（EEG）测量，以推断1mm范围内该点的电活动。如果这真的有效，那就太疯狂了。 **fuzzythinker**: In case you didn't scroll to the end, they open sourced their code:<p><a href="https://github.com/brain-hack-2024/transcranial-ultrasound/">https://github.com/brain-hack-2024/transcranial-ultrasound/</a> > **fuzzythinker**: 如果你没有；不要滚动到最后，他们开源了他们的代码：<p><a href=“https:/；/ github.com/-brain-hack-2024//经颅超声/.”>https:/；github.com；brain-hack-2024；经颅超声</一
