Abstract

The invention discloses an integrated eye and brain visual function imaging system. The system includes: a visual stimulus presentation device which presents pictures and videos comprising a plurality of stimulus-inducing patterns; an eye vision imaging device which is a retina and pupil imaging device based on multi-spectrum; a brain vision imaging device which is a visual cortex blood flow signal imaging device based on a spectrum technology related to near infrared diffusion; and a cooperative working station which comprises an imaging acquisition control module and an image analysis module and is used for cooperatively controlling the eye vision imaging device and the brain vision imaging device and processing and analyzing the acquired multispectral retina and pupil images and visual cortex blood flow images. The system can realize synchronous recording of nerve function response of eye retina, pupil and brain visual cortex, carry out joint analysis on multi-mode multi-parameter visual physiological signals, and provide a method for visual information coding and decoding, visual reconstruction mechanism research, visual nerve regulation and quantitative evaluation damage positioning and the like.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to an integrated eye-brain visual function imaging system. Background technique [0002] Due to the importance of visual function, research on visual nerve function has always been a hot spot at home and abroad. In terms of visual nerve functional imaging of the brain, commonly used devices include functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), and near-infrared functional brain imager (fNIRS). The principle of fMRI is to use dynamic magnetic resonance imaging to measure changes in blood oxygen levels caused by neuronal activity. The use of fMRI can realize the research on the functional positioning, color recognition, and visual processing of the cortex related to the human visual system. However, the temporal resolution of fMRI is low, and it cannot measure instantaneous brain neural activity changes. EEG can detect the electrical signals gener...
