A Silicon Based, Three Dimensional Microsystem for Stimula- tion of the Visual Cortex

这是一项完成新电极阵列开发以刺激大脑皮层神经元的提议。这个10x10硅基阵列在4.2 mm的正方形底座上被布置为一把“刷子”，将包含减少引线数量的电路。然后，这些电极将被植入猫的体感皮质，以评估用作记录和刺激装置的耐用性和生物兼容性。虽然该项目的最终目标是使用这种电极对盲人进行电刺激，以部分恢复一些视觉感觉，但电极阵列也应该有助于记录来自深层皮质结构的信息。

This is a proposal to complete the development of a new electrode array to stimulate neurons in the cerebral cortex. The 10x10 silicon-based array, arranged as a "brush" on a 4.2 mm square base, will contain circuitry to reduce the number of lead-wires. The electrodes then will be implanted into the somatosensory cortex of cats to evaluate durability and biocompatibility for use as both recording and stimulating devices. Although the eventual goal of the project is to use such electrodes for the electrical stimulation of blind individuals to partially restore some visual sensation, the electrode array should be also useful for recording information from deep cortical structures.
