Monoamine transmission: from mechanisms to 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
- Dopamine signalling dysfunction in Parkinson’s disease
- How drugs of addiction modify dopamine signals
- How dopamine controls behaviour
Please get in touch if you’d like to find out how to join the lab.

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.

On 2 March 2022, Dr Katherine Brimblecombe visited two primary school classes (ages 8-11) as part of their “Science week”. Read her interview to learn more about public engagement with school children in the local Oxford community.
13 April 2022
Researchers from the Oxford Parkinson’s Disease Centre (OPDC) recently hosted Caroline Rassell, Parkinson’s UK Chief Executive; David Dexter, Associate Research Director; Trustee Board members, Gary Shaughnessy (Chair) and Sally Bromley; together with members of the Parkinson’s UK Oxford Branch committee, for a visit to showcase the research being carried out in Oxford.
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 (firstname.lastname@example.org, 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.
