A system for testing spontaneous social interactions of group-housed mice placed in an experimental apparatus. The system includes a plurality of compartments (101-104) bridged by corridors (105). At least one compartment (101-104) has a perforated partition wall (106,107) separating the compartment into a territory available for mice (106b, 107b) and a territory to be explored by olfaction (106a, 107a). In the territory available for mice (106b, 107b), above the partition wall (106, 107), there is an infrared laser curtain (201). The system also includes a photographic device (202) for acquiring the intersection of a mouse in the light of the infrared curtain. In the territory to be explored by olfaction (106a, 107a), there is a source of olfactory stimuli (203).

A device is provided for studying the ability of at least one mouse to find its bearings in a maze, the device including a plurality of houses distributed around a central agora and in which at least one stimulator allows the at least one mouse to carry out certain activities and/or satisfy certain primary needs. Each house further includes at least one sensor for measuring the activity of the mouse in the house, and more particularly its use of the at least one stimulator. Finally, a sensor makes it possible to detect and measure the movements of each mouse in the device. Quantitative parameters originating from these measurements thus make it possible to highlight the quality of the geographical memory of the at least one mouse.

A system for monitoring vital signs of a pet animal comprises an annular band, an accelerometer configured to measure at least one of resting patterns, activity patterns, movement patterns, position patterns relating to, for example the pet animal relieving itself, lameness and scratching, and a non-accelerometer sensor configured to measure at least one of the following non-accelerometer-measured bioparameters of the pet animal: temperature, pulse rate, respiration rate. One or more processors are configured to receive sensor output data and reference data concerning the measured bioparameters of the pet animal or of a population of the pet animal, and determine a suspicion of a specific medical condition by: (i) scoring at least two bioparameters and comparing a cumulative score to a threshold cumulative score or to a threshold cumulative range; or (ii) identifying an abnormal pattern. The processor(s) may send an alert if at least one specific medical condition is suspected.

The application discloses a method, apparatus and system for scanning an animal. The method includes obtaining a species of an animal to be scanned, identifying a type of an animal cabin where the animal to be scanned is located, and determining whether the species of the animal to be scanned matches the type of the animal cabin, determining and presenting a corresponding scanning protocol that matches the species of the animal to be scanned if the species of the animal to be scanned matches the type of the animal cabin, and perform a scan according to the corresponding scanning protocol, or according to a user-defined scanning protocol.

The present disclosure relates to methods for measuring affective bandwidth of a subject (e.g., a human) and determining depression determination of the subject. The affective bandwidth measurement may include the following operations. For example, the subject may watch positive neutral and negative pictures for 8-10 seconds, respectively. Information for all fixation points may be obtained using an eye movement tracking device. Pupil diameter sizes of the subject while watching the positive, neutral and negative picture tasks may be calculated, and the affective bandwidth may be calculated. The affective bandwidth may include positive affective bandwidth (positive-neutral), negative affective bandwidth (negative-neutral) and positive-negative affective bandwidth (positive-negative) of the subject.

According to various embodiments, systems and methods for determining carbon dioxide detection in arthropods. An embodiment may include determining at least one resonant frequency of an arthropod sensory organ and an absorption spectrum of at least one odorant. A frequency filter may be applied to the absorption spectrum to eliminate frequencies below a given intensity value. Of the frequencies remaining from the absorption spectrum, those frequencies corresponding to relative peaks in absorption intensity may be selected. An olfactory chord including a group of the selected frequencies corresponding to the relative peaks in absorption intensity with at least one specific frequency that matches the at least one resonant frequency of the arthropod sensory organ. Additionally, at least one radiation source may be configured to emit electromagnetic radiation corresponding to the olfactory chord.
