Non-human primate visual sense and cognition function research system

Abstract

The invention discloses a non-human primate visual sense and cognition function research system comprising the following structures: a fixed seat including a seat, a lantern ring fixed system, a waist restrain plate, and a touch screen device portal frame; a water supply system including a water barrel, an electronic water valve and a NI acquisition card; a touch screen device having a visual sense stimulation touch screen capable of playing sounds for hearing stimulations and presenting images; an eye tracker including an infrared camera, an infrared lamp, an eye tracker body, and an interaction module; a controlling including an N1 acquisition card module, a touch screen module, an eye tracker module and a task module; the non-human primate visual sense and cognition function research system can obtain stable animal postures, thus further extracting animal eyeball motion direction characteristic vector and experiment animal cognition capability parameters; the system is high in interaction dimension, high in integration level, and high in experiment precision and efficiency.

Description

technical field [0001] The invention relates to the field of animal vision and cognitive function research methods, in particular to a non-human primate visual and cognitive function research system. Background technique [0002] The visual and cognitive functions of the brain have always been the focus of neuroscience research. As the closest experimental animals to humans, non-human primates have been widely used in related research fields. Although the central nervous system of such experimental animals is very similar to that of humans, since they cannot understand language or express their feelings in words, how to confirm their actual feelings and clarify the stimulus-response effects has always been a difficult problem to solve. [0003] Touch screens have long been used in the field of human cognition research. For example, the tablet-based 5-CSRTT task has been used to diagnose cognitive function in Alzheimer's patients. Due to its precise controllability and the...

AI Technical Summary

Problems solved by technology

[0004] However, most animal cognition research systems allow animals to move freely in front of the instrument and cannot restrict animal behavior

This design leaves the animal in a relatively uncontrolled state before and after the reaction, so it cannot be used to study limb movements, eye movements or record brain nerve signals
