Graham, Lauren K.; Yoon, Taejib; Kim, Jeansok J. – Learning & Memory, 2010
Stress is a biologically significant social-environmental factor that plays a pervasive role in influencing human and animal behaviors. While stress effects on various types of memory are well characterized, its effects on other cognitive functions are relatively unknown. Here, we investigated the effects of acute, uncontrollable stress on…

Eichenbaum, Howard; Fortin, Norbert J. – Journal of the Experimental Analysis of Behavior, 2005
The notion that non-human animals are capable of episodic memory is highly controversial. Here, we review recent behavioral work from our laboratory showing that the fundamental features of episodic memory can be observed in rats and that, as in humans, this capacity relies on the hippocampus. We also discuss electrophysiological evidence, from…

Rebec, George V.; Sun, WenLin – Journal of the Experimental Analysis of Behavior, 2005
The return to drug seeking, even after prolonged periods of abstinence, is a defining feature of cocaine addiction. The neural circuitry underlying relapse has been identified in neuropharmacological studies of experimental animals, typically rats, and supported in brain imaging studies of human addicts. Although the nucleus accumbens (NAcc),…

Winger, Gail; Woods, James H.; Galuska, Chad M.; Wade-Galuska, Tammy – Journal of the Experimental Analysis of Behavior, 2005
Neuroscientific approaches to drug addiction traditionally have been based on the premise that addiction is a process that results from brain changes that in turn result from chronic administration of drugs of abuse. An alternative approach views drug addiction as a behavioral disorder in which drugs function as preeminent reinforcers. Although…

Haddon, J. E.; Killcross, A. S. – Journal of the Experimental Analysis of Behavior, 2005
There is much debate as to the extent and nature of functional specialization within the different subregions of the prefrontal cortex. The current study was undertaken to investigate the effect of damage to medial prefrontal cortex subregions in the rat. Rats were trained on two biconditional discrimination tasks, one auditory and one visual, in…
