【medical-news】脑中植入迷你照相机记录记忆的形
TOKYO (Reuters) - Japanese researchers have implanted a small camera inside a mouse's brain to see how memory is formed, in an experiment they hope to some day apply to humans to treat illnesses such as Parkinson's disease.
The study, published in the "Journal of Neuroscience Methods" and "Sensors and Actuators", used a camera 3 mm (0.1 inch) long, 2.3 mm wide and 2.4 mm in depth, said Jun Ohta, professor at Nara Institute of Science and Technology in western Japan.
Working with researchers at Kinki University, Ohta implanted the special semiconductor camera inside the hippocampus of the mouse's brain, designing the devise so that a screen showed blue light whenever the camera captured memory being recorded by the brain.
The researchers injected the mouse with a substance that lights up whenever there is brain activity. The camera then captures that light and the visuals come up on a screen.
The team now plans to use the camera while the mouse is walking.
"We are thinking about how to apply this to humans, though we must be very careful, as it involves implanting something into the brain," Ohta told Reuters. "It would take 10 years at the earliest."
The researchers hope the study will lead to new ways to treat Parkinson's disease, as they aim to have the camera track brain activity that trigger symptoms such as tremors.

日本研究人员将微型相机置入老鼠脑内
TOKYO (Reuters) - Japanese researchers have implanted a small camera inside a mouse's brain to see how memory is formed, in an experiment they hope to some day apply to humans to treat illnesses such as Parkinson's disease.
东京(路透社)消息:一项试验中,日本研究人员们将一架小型相机植入老鼠脑内以探究记忆如何形成.他们希望由此,能在将来的某一天找到治疗诸如帕金森氏病等疾患的方法.
The study, published in the "Journal of Neuroscience Methods" and "Sensors and Actuators", used a camera 3 mm (0.1 inch) long, 2.3 mm wide and 2.4 mm in depth, said Jun Ohta, professor at Nara Institute of Science and Technology in western Japan.
该研究发布在"神经科学方法杂志"及"传感器及驱动器学报"上.来自日本西部地区的奈良先端科学技术大学院大学(NAIST)Jun Ohta教授介绍说,他们使用的是长X宽X高为3X2.3X2.4mm的照相机.
Working with researchers at Kinki University, Ohta implanted the special semiconductor camera inside the hippocampus of the mouse's brain, designing the devise so that a screen showed blue light whenever the camera captured memory being recorded by the brain.
Ohta教授与Kinki大学的研究人员们合作,将一个特制的半导体相机植入到老鼠脑内的海马内.当相机捕捉到记忆的时候,该装置的屏幕上会显示出蓝光.
The researchers injected the mouse with a substance that lights up whenever there is brain activity. The camera then captures that light and the visuals come up on a screen.
研究人员们在老鼠体内注射一种物质,该物质在脑活动的时候会发光,然后,相机就会发现这一情况,并在屏幕上显示出来.
The team now plans to use the camera while the mouse is walking.
研究团队目前计划在老鼠行走的时候使用该相机.
"We are thinking about how to apply this to humans, though we must be very careful, as it involves implanting something into the brain," Ohta told Reuters. "It would take 10 years at the earliest."
Ohta教授对路透社说,"我们正想办法将该技术运用于人类,但我们要倍加小心,毕竟是要在人的脑子里面装东西的事情.估计实现该技术移植人类至少需要10年时间."
The researchers hope the study will lead to new ways to treat Parkinson's disease, as they aim to have the camera track brain activity that trigger symptoms such as tremors.
研究人员们希望该研究对探索治疗帕金森氏病的方法能有帮助,他们希望这种相机能追踪到触发震颤症状的脑活动.
