Embodiment 1

[0015] Such as figure 1 As shown, the fixing device for fish auditory brainstem electrodes of the present invention includes an n-type elastic fixing belt 1, and the n-type elastic fixing belt 1 is made of elastic warp-knitted polyester velcro. The crossing side of two fixing straps of the n-type elastic fixing strap is defined as the top end, and the other end is defined as the bottom end. The top of the n-type elastic fixing belt 1 is provided with an electrode stabilizing base 2 in contact with the fish skull, and the electrode stabilizing base 2 is fixed on one end of the n-type elastic fixing belt by gluing. The central position of the stable electrode base 2 is equipped with an elliptical grid-shaped hollowed-out silicone pad 3, and a silicone pad 4 is arranged around the grid-shaped hollowed-out silicone pad. The silica gel liner 4 is used to protect the skin of the fish skull and make the electrode stable base 2 stable on the fish skull. The top of the n-type elastic...

Abstract

The invention provides a fixing device of a fish auditory brain stem electrode and an application of the fixing device to collecting a fish auditory brain stem electrical signal. The fixing device comprises an n-shaped elastic fixing strap, wherein two fixing buttons and two magic buttons are also arranged on the n-shaped elastic fixing strap; an electrode stabilizing base is arranged on the n-shaped elastic fixing strap; an elliptic latticed hollow silica gel cushion is mounted at the center position of the electrode stabilizing base; a silica gel liner is arranged on the periphery of the latticed hollow silica gel cushion; and the fixing device also comprises an electrode fixer for fixing an electrode to the electrode stabilizing base. The invention also provides the application of the fixing device to collecting the fish auditory brain stem electrical signal. The fixing device disclosed by the invention can be suitable for heads of fish in different shapes, and can fix and protect the brain stem electrode located to a skull of the fish, an electrode inserted in the skin of the head of the fish can be effectively fixed and protected, and high-precision requirements of potential measurement of auditory brain stem response of the fish are met.

Description

technical field [0001] The invention belongs to the field of fish physiological science research, in particular to a fixing device for fish auditory brainstem electrodes and its application in collecting fish auditory brainstem electrical signals. Background technique [0002] The environment can significantly affect the stress response, physiological state, and behavior of fish. The nervous system of fish is responsible for receiving and processing various information, evaluating the surrounding environment and its own state, and making behavioral and cognitive decisions that are conducive to the survival and reproduction of the organism. . Research on the nervous system can clarify how the structure and function of neurons and the neural circuits they consist of achieve complex cognition and behavior. After in-depth research on the central nervous system of fish, it will help to reveal the fish's understanding of various The response and coordination mechanism of environm...
