Embodiment Construction

[0031] Such as Figure 3-9 As shown, the pigeon brain three-dimensional four-point positioning device of the present invention includes a three-dimensional electrode moving device 2 fixed on the base plate 1 and left and right ear bar holders with the same structure, and the left and right ear bar clamps The holder includes a left column 3.1, a right column 3.2, a left ear bar 4.1, a right ear bar 4.2, a left side plate 5.1 and a right side plate 5.2 connected to the left ear bar 4.1 and the right ear bar 4.2; 1. A beak rod 6 is arranged between the right side plates 5.1 and 5.2. The left and right columns 3.1, 3.2 are all fixed on the base plate 1, and the left and right columns 3.1, 3.2 are provided with square through holes at an angle of 45° with the horizontal direction, so as to ensure that the fixed domestic pigeon beak angle-outer ear connection line and the horizontal plane It is at an included angle of 45°; the left ear bar 4.1 and the right ear bar 4.2, which are s...

Abstract

The invention discloses a stereotaxic four-point pigeon brain localization device comprising a three-dimensional electrode moving device fixed on a baseplate, a left ear rod holder and a right ear rod holder. The left and right ear rod holders are identical in structure, and each of the left and right ear rod holders comprises a column, an ear rod and a side plate connected to the ear rod; a coracoid bar is connected between the side plates of the left and right ear rod holders. The invention further discloses an operation method of the stereotaxic four-point pigeon brain localization device. The stereotaxic four-point pigeon brain localization device utilizes the lever principle and adopts a four-point localization method, namely two ears are localized and fixed with the ear rods, the coracoid bar is moved to the position between the nose and the coracoid corner of a pigeon to be localized and fixed, and then a pigeon coracoid adapter is butted against the part between the nose and the upper coracoid tip to be localized. Due to the fact that force of the coracoid bar is outward and force of the adapter is inward, the upper jaw bone of the pigeon is firmly clamped between the coracoid bar and the adapter just like a lever, the pigeon brain is reliably localized and fixed, and repeated localization accuracy is high.

Description

technical field [0001] The invention relates to the technical field of brain stereotaxic positioning, in particular to a pigeon brain stereoscopic four-point positioning device and an operating method thereof. Background technique [0002] Brain stereotaxic devices are important research equipment in the fields of neuroanatomy, neurophysiology, neuropharmacology, neuroengineering, and neurosurgery. The principle of brain stereotaxy is to use the markers on the surface of the skull (such as bregma) as the basic reference point, and determine the position of the subcortical nerve nuclei through three-dimensional movement, and then complete the directional injection, stimulation, and damage of the nerve nuclei. , signal detection and other operations. Therefore, the accuracy of positioning, especially the accuracy of repeated positioning, is an important measure of brain stereotaxic instrument. At present, the existing brain stereotaxic devices at home and abroad are mainly a...
