Animal retention apparatus, and method and applications thereof, having multiple support guides and a frame member with multiple passageways, the support guides being adapted for being inserted into the passageways and removably held at desired locations in the frame member, horizontally or at various angles to enhance retention of the animal, so that support guide would come in adjacent contact with an animal's anatomy to hold the animal in a desired position as the animal is positioned alongside the frame member. A method of working on an animal involves obtaining an embodiment of the animal retention apparatus and positioning the animal alongside a side of the frame member, placing support guides at height and width locations in the apparatus frame member that will hold the animal in a desired position, and working on sides of the animal that face away from the side of the frame member.

According to an example aspect of the present invention, there is provided an attachment and method for head-fixing rats for experimental purposes. The invention provides a tool for multi-region electrophysiology & precision monitoring of organismal state during complex cognitive tasks. The attachment for a skull of a rat, comprises a frame enclosing an open space inside the frame, at least one tooth on the frame extending from the frame towards the open space. Adhesive may be used as an attaching agent.

A holding device for simultaneously holding several small animals includes at least three beds each for a small animal. Each bed is attached to a respective holder element. The holding device is geometrically constructed and mechanically configured where two of the holder elements can be moved together with their respective beds above a third holder element without changing the vertical orientation of the beds being attached to the two holder elements. This provides a compact holding device for a multitude of small animals facilitating flexible and easy access to each small animal when attached to the holder for generating a 3D image of all animals at the same time, e.g., in an MRI, PET, CT scanner or the like. The holding system is easy to use, in particular for rats or mice, and can easily be applied in a wide variety of locations through its small and compact construction.

A head stage designed for non-surgical placement of EEG electrodes in small animals is disclosed. The head stage is connected to thin barbed pin electrodes of multiple lengths, such that they can be placed into the brain at the chosen depth. A miniature device comprising a wireless transmitter or data logger can be attached using magnets or connectors to the stage. When the head stage is placed on the head of a small animal and pressure is applied on the stage, the set of pin electrodes penetrate the skull, such that the stage becomes firmly fixed to the skull. Further, the device includes electrodes on its body that eliminate the need of wires for EEG recordings. When the capsule including sharp electrodes is pressed toward the skull, the electrodes penetrate the bone and fixes the capsule onto the skull for recording biopotential signals from the brain.
