Monoamine transmission: mechanisms, microcircuits and movement
The neurotransmitter dopamine in the brain is critical to how we choose our everyday actions, by signaling our motivations and selecting appropriate movements. When dopamine function is disrupted, a range of psychomotor disorders can result that include addiction disorders and Parkinson’s disease.
Our work explores how dopamine function is governed and dysregulated through study of dopamine transmission in real-time.
In a range of parallel and intersecting projects, we are exploring:
- Mechanisms on dopamine axons that govern dopamine output
- Circuits that govern dopamine transmission
- Dysregulation in dopamine and related neuromodulators in Parkinson’s disease
- How drugs of addiction modify dopamine signals
- Circuits that control behaviour
Please get in touch if you’d like to join the lab, and see current recruitment opportunities below.

Oxford Parkinson’s Disease Centre awarded £3.8 million to reveal the role of calcium in Parkinson’s
29 April 2022
A collaborative research team led by the Oxford Parkinson’s Disease Centre (OPDC) has been awarded a £3.8 million Wellcome Trust Collaborative Award to study the function of calcium in dopamine neurons, and how this is plays a role in Parkinson’s. Their research will help explain how and why dopamine neurons are vulnerable in the disease and look at how they may be preserved.
Welcome to the Dopamine Club!
Dopamine Club is an informal, lab meeting-style forum that brings dopamine researchers together from across the University to exchange and discuss our different perspectives on dopamine.
Dopamine Club was founded in 2014 to bring together dopamine researchers within the University and promote interactions towards the common goal of understanding dopamine function.
Anyone is welcome to attend, organise and participate in Dopamine Club meetings and we'd like it to be as interactive as possible so if you want to be involved please get in touch (email@example.com, or any of the other contributing groups).
Meetings are held termly, usually on Monday of 8th week, in DPAG. Meetings are chaired by different labs on a rotating basis.
