存储器由芯片、电极阵列和算法组成

可以恢复脑功能、并改善老鼠的短期记忆的神经植入物有一天可能帮助那些由患中风,老年痴呆症或其他脑损伤等引起的记忆力减退的病人。该装置有一个芯片、32个电极和非常复杂的算法组成,该算法解密并复制从大脑一层到另一层的代码。存储器由维克森林大学的神经生理学家Samuel Deadwyler和南加州大学的神经科学家兼生物医学工程师Wake Forest研究开发。《技术评论》报告,该存储器提供的证据表明,大脑的神经代码可以被破解和复制,以提高认知功能。植入物在老鼠恢复了功能非常有限,使它们记住拉了两个杠杆中的哪个。

当老鼠在畅通无阻地执行任务时,电极记录相关的大脑活动。这使研究人员能够映射的神经模式,表明短期记忆的形成。在一次试验中, 使用神经阻断药物来防止记忆的形成。当老鼠受到相应的神经冲动模式的刺激时,它们能够记住,如果“记住”是正确的描述方式,按正确的杠杆。

您可以阅读《技术评论》中通向假体内存的第一步,了解更多研究内容。
