Head games: How the mind works when gambling

In 2009, Winstanley’s Laboratory of Molecular and Behavioural Neuroscience created the world’s first animal lab experiment to model human gambling.

In their most recent study, 32 rats gambled for sugar pellets using a slot machine-style device that featured three flashing lights and two levers they could push with their paws. The rats exhibited several behaviours associated with problem gambling, such as the tendency to treat “near misses” in a similar way to wins. By blocking the D4 receptors with drugs, they were able to reduce this behaviour.
