Our Pharmacodynamics Department can deliver multiple nervous system models based on anti- depressants, anti Alzheimer’s drugs, sedative-hypnotic and anti-anxiety drugs, analgesics, anti- convulsant, anti Parkinson’s drugs, and anti schizophrenia drugs. Those models can effectively evaluate innovative drugs at the molecular and cellular level, as well as ex vivo, and in vivo. The Department’s advanced Cognition Wall Discrimination learning ensures uninterrupted tracking to determine changes in memory function in double transgenic mice during early-stage Alzheimer’s disease and eliminates the disadvantages of the Morris water maze (MWM) in stress interference and short-time tests.
