Abstract

The invention belongs to the cognitive technical field of brain science, and specifically relates to a near-infrared spectrum detection method for ambient light modulation of brain cognitive function. The method of the present invention uses functional near-infrared spectroscopy technology, combined with the classic paradigm Stroop of cognitive behavioral psychology, to explore the impact of environmental light changes on the cognitive function of the human brain, aiming at the frontal lobe region of the brain that has a strong correlation with the cognitive function of the human brain. Including designing the experimental environment, designing the psychological Stroop experimental stimulus rules, designing the experimental process, building the experimental system, and configuring the detection channel; using the Stroop psychological test method combined with functional near-infrared spectroscopy for testing; finally, fNIRS data processing; Images of brain activation regions under different lighting conditions, and through the t test, the brain region channels with significant differences (P<0.05) under different lighting conditions were obtained, which proved that the channels were activated due to changes in ambient light.

Description

Technical field

[0001] The present invention belongs to the field of brain science cognitive technology, and specifically, a method of near-infrared spectral detection of ambient light modulated brain cognitive function. Background technique

[0002] Brain function is the operational model presenting in the interaction of human and real world, revealing the mystery of brain function is one of the most important challenges facing humanity. Scientific development to today, human brain is still a unknown area. "Understanding Brain", "Protecting Brain" and "Creating Brain" is the goals and purpose of many countries to develop a brain scientific development plan. Among them, "understanding the brain" is not only to understand the anatomy of the brain. More importantly, it is necessary to understand the working mechanism of the brain, especially senior cognitive activities produced by the brain (learning, thinking, language, memory, emotion, etc.). Functional neural imaging provides a ...
