specific example

[0042] First, soak the carp in the eugenol aquatic anesthetic solution, then remove the anesthetized carp from the solution, fix it in the brain stereotaxic instrument, clamp the fish mouth horizontally, and gently pull upward to clamp the dorsal fin spine. Clamp the operculum on both sides to fix the 4 feature points to ensure that the fish is in a balanced state and centered.

[0043] Such as figure 1 As shown, the intersection of the midline of the skull surface and the junction of the first fish scale of the head and torso is set as the origin of the coordinate system (3), the midpoint of the upper lip is the lip point (2), and the vertical height H above the lip point is The position at is set as the reference point (1), and the straight line passing through the origin and the reference point is taken as the standard line. The horizontal plane passing through the standard line is defined as the horizontal reference plane, the plane passing through the standard line inclu...

Abstract

The invention discloses a carp electrode transforation implantation brain stereo positioning method, which belongs to the technical field of brain stereo positioning. The invention mainly solves the problem of accurate positioning in electrode implantation into brain without craniotomy. The method comprises the following steps: drawing a straight line centrally from the carp mouth to the intersection point between the head and the first scale of the trunk, and drawing a straight line parallel to the central line based on the upper edges of two orbits respectively; drawing a connection line along the front edges of the two orbits; drawing a connection line along the rear edges of the two orbits; drawing a connection line between the joint moving joint points of the operculum bones on the two sides and the orbit bones; and drawing a line through the joint between the head and the first scale of the trunk and vertical to the central line. The skull surface is divided into 6 areas by the 7 lines, each area representing a coordinate system. The mouth, dorsal fin and operculum on the two sides clamp 4 points for fixing; in the positioning of a brain stereotaxic instrument, an electrode is implanted into the brain along a skull hole, and magnetic resonance imaging equipment navigates and corrects deviation so as to realize three-dimensional accurate positioning without craniotomy. The invention is applicable to the collection of brain wave of aquatic animals or control on biological behavior by conduction of electrical signals.

Description

technical field [0001] The invention relates to a stereotaxic method for implanting electrodes into carp brain tissue without craniotomy, which belongs to the field of brain stereo technology, that is, establishes an electrode positioning area through carp skull surface marks, and uses a brain stereotaxic instrument to determine the coordinate position of the implanted electrode. The electrodes are drilled through the skull and implanted into the brain tissue, and the medical imaging equipment is used to navigate and correct the deviation, so as to realize the precise positioning of the implanted electrodes for brain signal processing or biological behavior control of aquatic animals. Background technique [0002] In modern scientific research, directional injection, stimulation, destruction, extraction of EEG, and biological behavior control of the brain all require the application of brain stereotaxic technology for precise positioning. In 1873 Dittmar first introduced the...
