APPARATUS FOR ACQUIRING ELECTRIC ACTIVITY IN THE BRAIN AND UTILIZATION OF THE SAME |
| 摘要 |
The present disclosure provides an apparatus including: one or more needle-like bases enabled to be inserted into the brain; a first electrode having a first impedance and enabling an input of an electric activity of a nucleus with which the first electrode comes into contact; and a second electrode having a second impedance lower than the first impedance and being able to output an electric stimulation to the nucleus, wherein the first electrode is provided at a tip portion of at least one of the bases, and the second electrode is provided on a part of the at least one of the bases at a position identical to a position of at least one of the first electrode or on a proximal side with respect to the first electrode, in a direction along a long axis of the base on which the first electrode is provided. |

1. An apparatus for identifying a target site in the brain, comprising:
one or more needle-like bases enabled to be inserted into the brain; a first electrode having a first impedance and enabling an input of an electric activity of a possible target site with which the first electrode comes into contact; and a second electrode having a second impedance lower than the first impedance and being able to output an electric stimulation to the possible target site, wherein the first electrode is provided at a tip portion of at least one of the one or more bases, and the second electrode is provided as a pair of an anode and a cathode on a part of the at least one of the one or more bases at a position identical to a position of at least one of the first electrode or on a proximal side with respect to the first electrode, in a direction along a long axis of the base on which the first electrode is provided, and the apparatus is configured to identify the target site by acquiring, from the first electrode, the electric activity induced based on the electric stimulation output from the pair of the anode and the cathode as the second electrode. |
