All the birds were measured for several social behaviors (social reinstatement, response to social isolation, sexual motivation, aggression), behaviors measuring the emotional reactivity of the birds (reaction to an unknown object, tonic immobility reaction), and production traits (body weight and egg production).
(Some scholars believe reinstatement was a response to a combination of economic recession and vigilante violence; lynchings in the Jim Crow South were common at the time).
The DBA/2J strain also failed to show significant reinstatement of this response when exposed to conditioned reinforcers alone.
Therefore, the aim of the present study was to assess the utility of various operant-based methodologies and procedures to characterize reward-related behavior in mice, focusing on the three aforementioned paradigms: auditory cue-induced PIT; acquisition, extinction and reinstatement of a stimulus-response (S R) instrumental response; and malaise-induced reinforcer devaluation.
The project assessed the vulnerability of utilities, identified interdependencies and developed practical strategies for reducing risk, and for response and reinstatement following a hazard event.
In addition, to assess the persistence and relapse of cocaine-seeking behavior in NR1DATCre animals, we studied the extinction and reinstatement of the CPP response.
The two subgroups examined in this study were defined by either the absence or presence of reinstatement of CPP in response to a priming dose of cocaine (10 mg/kg, i.p). on the test day following the confirmed extinction of the CPP.
Prefrontal cortical lesions differentially affected the reinstatement of drug-seeking responses after the return of rats to the test environment (F4,113 = 3.5; P = 0.01) (Fig. 3).
Sen. Jeanne Shaheen (D-N.H ., the only woman on the Senate Foreign Relations Committee, tolD-N.H .gn Policy thet she is planning a legislative responly to the reinstatement of global gag rule.
We describe a procedure for demonstrating PIT, and a method for studying acquisition, extinction and multiple forms of reinstatement of an instrumental touchscreen response.
We employed the CPP paradigm to investigate the extinction and reinstatement of the place-conditioned response to MDMA injection, a model that is consistent with drug-seeking behavior.
