Seat for marmoset for experiments

Abstract

The invention discloses a seat for a marmoset for experiments. The seat comprises a vertically arranged main support column, a support panel horizontally fixed to the upper end of the main support column, a base fixed to the lower end of the main support column, a seat main body arranged on the lower portion of the support panel and a head fixing frame arranged on the upper side of the support panel; the seat main body comprises a body restraint cylinder vertically fixed to the portion, in front of the main support column, of the lower surface of the support panel and a bottom seat board connected to the portion, below the body restraint cylinder, of the main support column, the vertical position of the bottom seat board is adjustable, and an arm space which is communicated with the body restraint cylinder and extends forwards is formed in the front side of the upper portion of the body restraint cylinder; a top outlet which extends backward to reach the portion above the body restraint cylinder is formed in the middle of the front end of the support panel. By means of the seat for the marmoset for the experiments, the marmoset can be restricted for a long time, so that the experiments such as marmoset behavioristics, electrophysiology and two-photon imaging can be conducted smoothly.

Description

technical field [0001] The invention relates to an experimental device for researching primates, in particular to an experimental device for a two-photon imaging experiment, and in particular to an experimental marmoset chair. Background technique [0002] Primates are close relatives of humans and have a high genetic similarity with humans. Therefore, the research objects in fields such as neuroscience will eventually fall on non-human primates. At present, the most commonly used primate in the laboratory is macaque, and there are mature macaque chairs at home and abroad, which can be used for behavioral experiments and electrophysiological experiments, but the latest research (Li et, al, 2017, Neuron) has only appeared A macaque chair and supporting experimental methods dedicated to two-photon imaging experiments. The size of a macaque is usually equivalent to a 5-year-old child, but its aggressiveness is more than that of an adult. Therefore, the macaque seat must first ...

AI Technical Summary

Problems solved by technology

[0003] Marmosets are less than one-tenth the size of rhesus monkeys. Compared with rhesus monkeys, they have the advantages of small size, fast reproduction, docile temperament, safety and easy operation, and gradually mature transgenic animal models. They are more likely to become non-human primates in vivo two-photon imaging The model animals studied, but there is no special marmoset chair in China at present, and there is no marmoset chair dedicated to two-photon imaging at home and abroad, and the relevant experimental technology for two-photon imaging of awake marmosets has not yet been developed. Furthermore, the development of relevant scientific research devices and experimental technologies is of great significance, and major laboratories are potential users
