Dopamine Receptors Scientific Review
Written by Phillip Strange and revised by Kim Neve in 2013, this review summarizes the history of the dopamine receptors and provides an overview of individual receptor subtype properties, their distribution and identifies ligands which act at each receptor subtype. Compounds available from Tocris are listed.
The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.
