Non-motor symptoms: thinking and memory
Dopamine neurons (brain cells) in the substania nigra Biggest impact

Healthy Parkinson’s disease
Habits are good! Habits allow you to automate behaviour and multi-task Habits depend on the putamen Do people with PD have trouble learning habits?
How do you measure habits?
- Habitual actions are
automated
- Goal-directed actions
require thinking about consequences

Next steps
- Determine whether
humans have trouble developing habits
- Determine if current
medications help restore habits (e.g., L-dopa)
- Chemogenetics
chemogenetics
- Insert receptors into brain cells
- Receptors are responsive to a
special chemical
- Consume chemical in a tablet
- Activate the putamen
