Abstract

The invention discloses a rat-intracranial-implantation microfilament array electrode suitable for an experiment and a manufacturing method thereof. The electrode is formed by a plurality of electrode microfilaments, a dosing conduit and the like. The electrode microfilaments are arranged in parallel and form a microfilament measurement electrode array and a microfilament stimulation electrode array respectively. The electrode manufactured through using the method of the invention can simultaneously realize three functions of experiment rat brain electric signal recording, electrical stimulation and drug stimulation. According to a specific demand, one or any two functions can be selected. And self-manufacturing can be completed with low cost.

Description

technical field [0001] The invention relates to a self-made intracranial multi-functional self-made electrode suitable for rats, which is suitable for the experimental operation of giving electrical stimulation and (or) drug stimulation to the experimental rat brain inner group while detecting the discharge of the inner group of the brain. It can also be used alone to record group discharges in the rat brain. Background technique [0002] In vivo detection of rat nuclei discharge is a common technique in the field of neuroscience research. This experimental technique obtains the firing information of neurons by implanting electrodes in the brain of rats. With the deepening of neuroscience research, more and more experiments have begun to explore the relationship between different brain groups. As a result, a variety of intracranial implant electrodes with complex functions have been derived, including array electrodes for collecting multi-nuclear group discharge informatio...
