System for a toximeter, having inclined separators

Abstract

The invention relates to a cage (1) for the behavioral study of living organisms, in particular for a toximeter, comprising at least one compartment (2) intended to hold a living organism, the cage (1) being transparent at least on an observation side (4) in order to allow the observation of the living beings from an observation point (10) located at a distance from the observation side (4), the compartment (2) being delimited by separators (3), characterized in that the wall (31a) of one separator (3a) is inclined with respect to the wall (32b) of another separator (3b) such that the walls (31a, 32b) of the separators (3a, 3b) of a compartment (2) are closer together in the direction of the observation side (4), said separators (3a, 3b) being aligned along convergence lines that meet at the observation point (10).

Description

technical field

[0001] The present invention relates to the field of behavioral or behavioral studies of living organisms, in particular toxicology, and more particularly to the field of monitoring living organisms in toxicometers. Background technique

[0002] In order to study the behavior of living organisms in a given environment, in particular the toxicity of the source of exposure, it is known to use living organisms that are usually selected on the basis of their biomarker quality (i.e. their propensity to respond to the environment), Especially in the presence of toxic substances. Small organisms, such as arthropods, are often used due to their ease of use and small size. These organisms are exposed to the exposure source and their evolution is then analyzed to detect and possibly quantify the toxicity of the exposure.

[0003] One analytical approach involves monitoring these living organisms throughout the exposure period to study their behavior and infer the tox...
