Abstract

The invention discloses a neural photoelectrode and a preparation method thereof, belonging to the field of neural photoelectrode preparation, wherein the neural photoelectrode comprises: a sapphire optical array device, a metal wire electrode and an ultraviolet glue; the metal wire electrode passes through the ultraviolet glue fixed on the surface of the sapphire optical array device. The invention adopts the method of attaching the sapphire optical array and the wire electrode to isolate the stimulation channel and the recording channel in a spatial range, effectively reducing the electrical stimulation noise; it is easy to assemble, and the position and quantity of the wire electrode can be assembled according to the demand ; The light source adopts light array, which is beneficial to stimulate and record multiple brain regions, and realize high-throughput detection of neural activity.

Description

technical field [0001] The invention relates to the field of nerve photoelectrode preparation, in particular to a nerve photoelectrode and a preparation method thereof. Background technique [0002] The brain is the system with the most complex structure and function in the living body. It is composed of hundreds of billions of nerve cells. These cells rely on two modes of pulse discharge and neurotransmitter release to complete various complex information transmission and integration functions. Comprehensive, accurate, real-time, and synchronous detection of these multi-dimensional information is a basic means and an important way to promote the detection, diagnosis, and rehabilitation of major neurological diseases. Electrodes traditionally used to monitor brain neural activity use electrical stimulation to stimulate and record neurons. This method is not selective for neurons and will cause irreversible damage to cells. Therefore, people use a combination of optical techn...
