Brain cells in the avian 'prefrontal cortex' code for features of slot-machine-like gambling.

Slot machines are the most common and addictive form of gambling. In the current study, we recorded from single neurons in the 'prefrontal cortex' of pigeons while they played a slot-machine-like task. We identified four categories of neurons that coded for different aspects of our slot-ma...
