Abstract

The invention discloses a backpack type wireless optical stimulation device and a backpack type wireless optical stimulation method. The backpack type wireless optical stimulation device comprises an optical fiber, an optical fiber coupling device, a backpack control circuit, a laser light-emitting diode (LED), an upper computer, a wireless transmission module and a wireless receiving module, wherein the wireless transmission module is matched with the wireless receiving module; the backpack control circuit comprises a microprocessor and a light source drive circuit which are electrically connected with each other; the optical fiber coupling device comprises a shell, an LED connecting piece, an optical fiber coupling lens component and an optical fiber collimator; the upper computer transmits a stimulation command to the backpack control circuit through the wireless transmission module and the wireless receiving module; the backpack control circuit receives the stimulation command and converts electrical signals into a series of optical signals representing optical stimulation characteristics; and the optical signals are transmitted into a light-sensing gene brain region of a target animal through the optical fiber coupling device and the optical fiber, so that the optical stimulation effect on the light-sensing gene brain region is achieved. The invention provides an optical stimulation mode, which is portable, stable, low in power consumption, convenient to use and small in distance limit and has wide application prospect in the field of neural engineering.

Description

technical field [0001] The invention relates to a backpack type wireless light stimulation device and a method thereof, in particular to a backpack type wireless light stimulation device for rodents and a method thereof. Background technique [0002] In the field of neuroengineering, brain-computer interface (Brain-Computer Interface, BCI) technology and its system is one of the important research branches, which aims to establish a direct information exchange channel between the biological brain and the external environment. In brain-computer interface technology, information feedback from external devices or the environment to the biological brain can include various modal methods, such as vision, hearing, smell, electrical / optical stimulation, etc. Among them, both optical stimulation and electrical stimulation can directly act on the specific neural structure of the biological brain, and can simulate real tactile input, which is an important mode of feedback from the ext...
