The Sensory and Motor Phenotyping Platform of INM is specialized in production and pre-clinical analysis of animal models, mainly murine, reproducing the major sensory and motor disorders that affect humans: blindness, deafness, tinnitus, dizziness, pain, and locomotor deficits.

The platform hosts the animal models of two INSERM units located at INM (844 and 1051) and the Institute for Research in Biotherapies (IRB).

It is composed of  both conventional and A2 sectors and aims at:
1. Exploring visual, auditory and somatosensory functions as well as locomotor systems
2 . Developing cell and gene therapy protocols in pre-clinical trials.

The platform is part of the Network of Animal Facilities of Montpellier (RAM) which participates to the activity of Biocampus. As such, it is open to all academic and private scientific community to host animal models and allow the characterization of their sensory and motor skills.
All projects must be submitted to the engineer in charge of the research board. If the project comes from external teams to the INM, it must also be approved by the steering committee of the platform.


The platform provides behavioral (proprioception, locomotion, vision, hearing, balance) and electrophysiological (vision, hearing) non-invasive analysis systems.






Catwalk® (Noldus Information Technology) allows to measure locomotor deficits due to various pathologies (joint diseases, pain, neurodegenerative disorders) through the analysis of paw prints during spontaneous locomotion.


Automated actimeter

Automated Actimeter


The automated actimeter (Bioseb) measures the overall locomotor activity (activity, rest, distance traveled) in a closed arena scanned by infra-red beams.



Automated videotracking



Ethovision® (Noldus Information Technology) analyses the overall locomotor activity of animals based on video recordings. It completes and deepens the data acquired with automated actimeter.








The rotarod (Bioseb) measures the capacity of animals to stay in balance on a rotating cylinder. It is used to phenotype balance, proprioception and locomotor system.







 tapis roulant2

The treadmills (1 and 5 lanes, Bioseb) are designed to train mice to physical exercise. They can be coupled with other tests to detect locomotor deficits or fatigue.



Grip test



The grip test (Bioseb) measures muscular strength of animals grasping on a metal grid. It is used to phenotype neuromuscular functions.









The microscanner SkyScann 1196® (Brucker) allows to perform longitudinal studies of bone and cartilage structures in rodents. It belongs to national platform ECELL France, localized at IRMB. Any project using microscanner needs a preliminary contract or order between user and ECELL France.








Dynamic plantar analgesia and Von Frey

Plantar Analgesia



Dynamic plantar analgesia (IITC Life Sciences) and dynamic Von Frey (Bioseb) respectively allow to measure sensitivity to mechanical or thermal stimuli. They are widely used in projects dealing with pain and analgesia following therapeutic treatments.

Thermal Gradient

Thermal Gradient


The thermal gradient (Bioseb) measures the comfort temperature of animals, free to move on a metal floor from 5 to 55°C. It is used to phenotype sensitivity and pain.


Static weight bearing

Static Weight Balance


The static weight bearing test (Bioseb) investigates postural imbalance by measuring the difference in left and right paw pressures. It is useful to phenotype sensitivity and pain in hind limbs.








This test (Bioseb) measures the rat sensitivity to mechanical paw pressure on hind paws. It is used to test analgesia following therapeutic treatments.



Conditioned Place Preference (CPP)

préférence de place


CPP (Bioseb), coupled to Ethovision® videotracking system, measures spatial place preference or aversion following conditioned stimulus.





Optokinetic Test


This test (CerebralMechanics Inc.) assesses visual acuity by measuring the ability of mice to visually follow-up vertical bars in motion.


Optical Coherence Tomography




This tomography imaging system (Leica) allows to visualize and measure the thickness of the various retina cell layers to monitor injury or recovery over time.



Retinal imaging microscope


The Micron III microscope (Phoenix Research Laboratories) allows to image retina and blood vessels (bright field and fluorescence).




ERG grand


The electroretinogram (SIEM Bio-Médicale) measures the electrical activity of optic nerve and retinal cells (ganglion and bipolar cells, cones and rods).






Anechoic Chamber 1

Electrophysiological set ups allow to measure auditory evoked potentials, electrical activity of inner and outer hair cells and otoacoustic emissions. An anechoic chamber is used to isolate animals from surrounding noise.





Startle response



This test is used to study the animal's startle reaction to sound stimulation. It allows to discriminate tinnitus or hearing loss in surrounding noise.





CCD Camera



This equipment (Berthold) is used to detect bioluminescence in vivo. It allows to monitor the expression of reporter genes in tissues or tumor development.
