Find your test

NEUROFIT offers a variety of well-accepted behavioral tests to assess the potential anxiolytic, antidepressant or antipsychotic effects as well as cognitive enhancing and disrupting effects on learning and memory (cognition, psychiatry, neurology). We have developed a comprehensive range of rat primary neuronal culture models and assays to evaluate neurotoxicity, neuroprotective or neurotrophic effect of test compounds (cellular models).

According to your target indications we can establish a screening program for your drug project.
In-house expertise allow us to assist you in most CNS and PNS disorders.

Under a Master Services Agreement a program can be established, where you work directly with the scientist responsible for the testing as if this person was working in your own laboratory. This will allow you to rapidly obtain access to already validated screening methods and to draw on our in-house expertise.
Data reporting, study performance etc... will of course be adapted to your specific needs during your direct interactions with the responsible scientist.
