Chronic nicotine increases midbrain dopamine neuron activity and biases individual strategies towards reduced exploration in mice

Chronic nicotine exposure impacts various components of decision-making processes, such as exploratory behaviors. Here, the authors identify the cellular mechanism and show that chronic nicotine exposure increases the tonic activity of VTA dopaminergic neurons and reduces exploration in mice.
