Functional magnetic resonance imaging synchronous monitoring and triggering stimulation control system

Abstract

The invention discloses a functional magnetic resonance imaging synchronous monitoring and triggering stimulation control system. The technical scheme includes that the system comprises an upper computer, a lower computer and magnetic resonance imaging equipment; the upper computer is used for carrying out man-machine interaction and controlling the lower computer; the lower computer is used for processing communication and interaction with the magnetic resonance imaging equipment, stimulation tasks can be generated by a stimulation task generating module in the lower computer on the basis of instructions emitted by the upper computer, a monitoring module in the lower computer is communicated with the upper computer, and reaction parameters, which are measured by the magnetic resonance imaging equipment, of tested objects can be recorded when the stimulation tasks are carried out, and can be fed to the upper computer. The functional magnetic resonance imaging synchronous monitoring and triggering stimulation control system has the advantages that central control and hardware interfaces can be unified, triggering signals can be synchronously received when magnetic resonance images are scanned, various physiological parameters of primates can be synchronously recorded, and the functional magnetic resonance imaging synchronous monitoring and triggering stimulation control system is suitable for software and hardware technical platforms for the stimulation tasks for vision, touch and the like of the primates.

Description

technical field [0001] The invention relates to a magnetic resonance imaging matching device, in particular to a functional magnetic resonance imaging synchronous monitoring and trigger stimulation control system. Background technique [0002] In recent years, functional magnetic resonance imaging (fMRI), as an emerging research method, has been widely used in the field of cognitive neuroscience research to explore the brain mechanism of human cognitive processes and emotional activities. In addition to directly using humans as research objects, non-human primates, as the closest relatives of humans, have brain structures similar to humans and possess advanced brain functions, and can be trained to complete specific types of test tasks. It has an irreplaceable role in evaluating cognitive ability and emotional response, etc., and is an ideal animal model for basic research on the normal function of the human brain and disease pathology research. A direct effect of these res...

Problems solved by technology

[0004] However, at present, the research on the implementation methods, types and structures of simultaneous physiological monitoring and trigger stimulation in primate (including human) fMRI experiments is not perfect. The design of the experimental program for the purpose of the experiment greatly reduces the repeatability of the experiment and makes the scientific nature of the experimental results questioned.

Not only that, because it involves the cooperation of multiple devices, experimenters often need to operate multiple devices at the same time, and the devices cannot be synchronized in time, which further reduces the reliability of the data
