Subdomains contributing to effort-based decision making. Effort-based decision making is a critical component of negative symptoms in schizophrenia and can be readily assessed in humans and rodents. Further, subdomains are identified whose neural mechanisms can be investigated in rodent studies. Dopamine D1 receptors have been implicated in each aspect of decision making, while dopamine D2 receptors contribute toward physical effort and reward-associative learning. Both cannabinoid CB1 and α7 nicotinic acetylcholine receptors have been implicated in reward associative learning, while CB1 receptors may also drive cognitive effortful motivation.
