The ventral striatum (VS) is thought to serve as a gateway whereby associative information from the amygdala and prefrontal regions can influence motor output to guide behavior. If VS mediates this "limbic-motor" interface, then one might expect ...

Appetitively motivated instrumental learning in SynGAP heterozygous knockout mice.
29 Sep 2009 The synaptic Ras/Rap-GTPase-activating protein (SynGAP) regulates specific intracellular events following N-methyl-d-aspartate receptor (NMDAR) activation. Here, the impact of SynGAP heterozygous knockout (SG+/-) on NMDAR-dependent functions was ...

Interval timing accuracy and scalar timing in C57BL/6 mice.
29 Sep 2009 In many species, interval timing behavior is accurate-appropriate estimated durations-and scalar-errors vary linearly with estimated durations. Whereas accuracy has been previously examined, scalar timing has not been clearly demonstrated in house ...

14 Sep 2009 Encounters with stimuli associated with drug use are believed to contribute to relapse. To probe the neurobiology of environmentally triggered drug use, we have conducted single-unit recordings in rhesus monkeys during presentation of two distinct ...

The convergence of information about rewarding and aversive stimuli in single neurons.
14 Sep 2009 Neuroscientists, psychologists, clinicians, and economists have long been interested in how individuals weigh information about potential rewarding and aversive stimuli to make decisions and to regulate their emotions. However, we know relatively ...

30 Aug 2009 We used a three-component multiple-schedule with a brief reversal design to evaluate the effects of structurally unmatched and matched stimuli on immediate and subsequent vocal stereotypy that was displayed by three children with autism spectrum ...

Using descriptive assessment in the treatment of bite acceptance and food refusal.
10 Aug 2009 The feeding behaviors of two children who maintained failure to thrive diagnoses and displayed food refusal are assessed in their homes. Descriptive assessments are used to identify schedules of consequence provided by each child's care providers ...

Yoked delivery of cocaine is aversive and protects against the motivation for drug in rats.
30 Jul 2009 In Experiment 1, water-deprived rats had 5-min access to saccharin followed by active or yoked intravenous delivery of saline or cocaine (0.33 mg/infusion). Both cocaine groups avoided intake of the saccharin cue following saccharin-cocaine ...

Effects of free food deliveries and temporal contiguity on choice under concurrent-chain schedules.
30 Jul 2009 Eight pigeons responded in a concurrent chain with variable-interval (VI) 10-sec and VI 20-sec terminal links. Free food deliveries were then added to the initial links according to a variable-time (VT) 20-sec schedule in two conditions that ...

Examination of reinforcement magnitude on the pharmacological disruption of fixed-ratio performance.
30 Jul 2009 Behavioral momentum theory proposes that operant behavior is the product of two separable processes: its rate of occurrence and its resistance to change. Generally speaking, operant situations providing more densely spaced or greater magnitudes of ...
