PARKINSON'S DISEASE
LATE-ONSET
PARKINSON'S disease.
AT THE BRAIN LEVEL.
Inside the brain, neurons in the pars compacta of the substantia nigra normally transmit dopamine to the striatum.
In Parkinson’s disease (PD), the degeneration of dopaminergic neurons leads to dysfunction of this neuronal circuit, especially in the motor cortical areas.
As a result, PD patients have their life severely impacted by motor disabilities or abnormalities.
PRECLINICAL RESEARCH
needs predictive translational objective functional biomarkers
BETA WAVES
TRANSLATIONAL EEG biomarker
Using EEG recording, a closer look at the brain’s neural activity reveals excessive synchronization in the Beta frequency range of PD patients’ motor cortex.
These low frequencies (Beta waves) are transiently reduced by dopamine agonists such as L-DOPA. Likewise, the 6-OHDA rat model of Parkinson’s disease shows a stable and pharmacosensitive Beta signature in vivo, which makes it clinically-relevant for preclinical anti-PD compound testing.
Augment the predictability of your compound performance on PD syndrome with the 6-OHDA model and BetaPark!
BETApark is objective & stable over time
A stable and specific Beta oscillation (BetaPark) is found in the motor cortex of the unilateral 6-OHDA rat model of PD, as found in PD patients.
This translational biomarker is:
- Pharmacosensitive
- Incredibly stable over time
- Objective, measured inside the motor cortex
- Exclusively revealed by Cue® and EEG
PHARMACOSENSITIVE biomarker of parkinson's disease
DOPAMINERGIC DRUGS transiently stop betapark
