Neurotoxic lesions of the dorsal and ventral hippocampus impair acquisition and expression of trace-conditioned fear-potentiated startle in rats
Autor: Mehul A Trivedi, Gary D. Coover
Publikováno v: Behavioural Brain Research. 168:289-298
Pavlovian delay conditioning, in which a conditioned stimulus (CS) and unconditioned stimulus (US) co-terminate, is thought to reflect non-declarative memory. In contrast, trace conditioning, in which the CS and US are temporally separate, is thought

Lesions of the ventral hippocampus, but not the dorsal hippocampus, impair conditioned fear expression and inhibitory avoidance on the elevated T-maze
Autor: Gary D. Coover, Mehul A Trivedi
Publikováno v: Neurobiology of Learning and Memory. 81:172-184
The hippocampus has been suggested to be involved in spatial (or configural) memory and also in the inhibition of certain response or goal alternatives. An increasing number of anatomical, physiological, and behavioral studies indicate that the hippo

Posttraining but not pretraining lesions of the hippocampus interfere with feature-negative discrimination of fear-potentiated startle
Autor: William A. Falls, Scott A. Heldt, Gary D. Coover
Publikováno v: Hippocampus. 12:774-786
Previous studies have suggested that the hippocampus may play an important role in some forms of inhibitory learning. The goal of the present study was to assess whether the hippocampus is also important for inhibition of fear acquired after serial f

Subtotal lesions of the amygdala: The rostral central nucleus in passive avoidance and ulceration
Autor: Robert Murison, Gary D. Coover, Finn Konow Jellestad
Publikováno v: Physiology & Behavior. 51:795-803
Rats received small bilateral electrolytic or ibotenate lesions of the rostral part of the amygdaloid central (rACE) or lateral (rAL) nuclei, or caudal part of the basolateral nuclei (cBL), or electrolytic lesions of the dorsal hippocampus (HIPP). Al

Effects of small amygdala lesions on fear, but not aggression, in the rat
Autor: Gary D. Coover, Michael E. Oakes
Publikováno v: Physiologybehavior. 61(1)
The effects of amygdala lesions on passive avoidance of drinking (dPA) and social interactions in a resident-intruder test were examined in two experiments that utilized different lines of Long-Evans hooded rats. The lesions were fairly well restrict

Double dissociation of passive avoidance and milk maze performance deficits with discrete lesions of substantia innominata or globus pallidus of rats
Autor: Gary D. Coover, Robert C. Meyer
Publikováno v: Behavioural brain research. 72(1-2)
In three experiments, small bilateral lesions of the substantia innominata (SI), globus pallidus (GP) and central nucleus of the amygdala (ACe) produced deficits in passive avoidance of drinking (dPA) or escape performance in a milk maze (MM). Severe

Motor debilitation, short- and long-term shuttlebox deficits, and brain monoamine changes following footshock pretreatment in rats
Autor: Gary D. Coover, Carlton E. Lints, Betty R. Sutton
Publikováno v: Physiological Psychology. 9:127-134
Male hooded rat triplets, each consisting of an unshocked control (C), an animal that could escape from the shock by leverpressing (LE), and a yoked animal that received noncontingent shock (NC), were pretreated with either short-duration, high-inten

Meal-induced decreases in serum corticosterone in the lateral hypothalamic syndrome
Autor: Gary D. Coover, Stephen Welle
Publikováno v: Physiology & Behavior. 23:547-555
Decreases in serum corticosterone levels were used to quantify positive emotional responses to meals in rats that survived bilateral lateral hypothalamic lesions (n=9), intraventricular 6-hydroxydopamine injections with pargyline pretreatment (n=3),

Conditioning decreases in plasma corticosterone level in rats by pairing stimuli with daily feedings
Autor: John P. Heybach, Gary D. Coover, Betty R. Sutton
Publikováno v: Journal of Comparative and Physiological Psychology. 91:716-726
This study examined the nature of a stimulus-induced decrease in the plasma corticosterone levels of rats. Rats maintained on a 23-hr food and water deprivation regimen were fed each morning immediately upon entrance of the experimenter into the othe
