The behavioral economics of drug self-administration: A review and new analytical approach for within-session procedures

Conclusion  The exponential demand equation can be fit to single-session data using the threshold procedure for cocaine self-administration.
Removing data points that occur during relatively unstable brain cocaine concentrations resulted in more accurate estimates
of demand curve slope than graphical methods, permitting a more comprehensive analysis of drug self-administration via a behavioral–economic
framework.

Guanfacine modulates the influence of emotional cues on prefrontal cortex activation for cognitive control

Conclusions  These results provide evidence that guanfacine stimulation of postsynaptic α2 adrenoceptors moderates DLPFC activation associated with the emotional biasing of response execution processes. The findings
have implications for the α2 adrenoceptor agonist treatment of attention-deficit hyperactivity disorder.

Cariprazine, a dopamine D3-receptor-preferring partial agonist, blocks phencyclidine-induced impairments of working memory, attention set-shifting, and recognition memory in the mouse

Conclusions  In an animal model of PCP-induced cognitive impairment, cariprazine pretreatment significantly diminished PCP-triggered cognitive
deficits, and studies on knockout mice show that dopamine D3 receptors contribute to this effect.
