The present invention relates to a kind of water maze device in the experimental research of the cerebral ischemic rat cognitive dysfunction, comprises the water pool that constitutes by pool wall and pool bottom, also comprises the platform that is used for floating in described water pool, and platform comprises A buoyancy box with a buoyancy chamber, a magnetic body is arranged on the platform, and the water maze device also includes a magnet for being fixed on the underside of the pool bottom to absorb the magnetic body, and the volume of the buoyancy chamber is adjustable and / or The magnetic force of the magnet is adjustable. The present invention provides a labyrinth device in the experimental research of cognitive dysfunction in cerebral ischemic rats, to solve the problems in the prior art that the overall height of the platform is high, and the bottom of the platform is easy to produce optical refraction, which confuses the vision of rats technical problem.
Description
technical field [0001] The invention relates to a labyrinth device in the experimental research of cerebral ischemic rat cognitive dysfunction in the field of animal experiments. Background technique [0002] Chronic cerebral circulation insufficiency (CCCI) was proposed by Japanese scholars in 1990, which refers to the fluctuation of subjective symptoms such as headache and dizziness caused by cerebral arterial circulation disturbance. At present, there is no exact and generally accepted definition of CCCI, but it is generally considered to be a common ischemic cerebrovascular disease, which exists in about 2 / 3 of people over 60 years old. CCCI is closely related to many cerebrovascular diseases, especially vascular dementia (VD) and Alzheimer's disease (AD). degree. Cerebral circulation disorders caused by various reasons can cause insufficient blood supply to the brain. Long-term CCCI causes chronic ischemia in the brain, resulting in varying degrees of pathological dam...
