Fixing device of fish auditory brain stem electrode and application of fixing device to collecting fish auditory brain stem electrical signal

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...

AI Technical Summary

Problems solved by technology

In order to record the auditory brainstem response of fish, it is necessary to maintain the fish in a state of life activity and carry out subsequent electrophysiological studies. At the same time, two electrodes inserted at a depth of 0.1-0.5mm under the skin of the fish head must be effectively fixed and fixed. Protection, otherwise it will seriously affect the measurement accuracy of ABR potential due to improper fixing position or unstable fixing

However, there is still a lack of an electrode fixation device for collecting fish auditory brainstem electrical signals
