Amygdaloid and non-amygdaloid fear both influence avoidance of risky foraging in hungry rats.

Considerable evidence seems to show that emotional and reflex reactions to feared situations are mediated by the amygdala. It might therefore seem plausible to expect that amygdala-coded fear should also influence decisions when animals make choices about instrumental actions. However, there is not good evidence of this. In particular, it appears, though the literature is conflicted, that once ...

Effects of amygdaloid and amygdaloid-hippocampal lesions on object recognition and spatial working memory in rats.

Neurotoxic lesions of the amygdala did not affect the postoperative acquisition of a nonspatial test of object recognition (delayed nonmatching to sample) even when retention delays were increased from 0 s to 20 or 60 s, or when test stimuli were deliberately repeated within a session. Although these amygdaloid lesions did not alter forced-choice spatial alternation, they slightly increased neo...

Curcumin inhibits amygdaloid kindled seizures in rats.

BACKGROUND Curcumin can reduce the severity of seizures induced by kainate acid (KA), but the role of curcumin in amygdaloid kindled models is still unknown. This study aimed to explore the effect of curcumin on the development of kindling in amygdaloid kindled rats. METHODS With an amygdaloid kindled Sprague-Dawley (SD) rat model and an electrophysiological method, different doses of curcumi...

The Lateral Amygdaloid in Fear Conditioning Nucleus: Sensory Interface Amygdala

Previous work has implicated projections from the acoustic thalamus to the amygdala in the classical conditioning of emotional responses to auditory stimuli. The purpose of the present studies was to determine whether the lateral amygdaloid nucleus (AL), which is a major subcortical target of projections from the acoustic thalamus, might be the sensory interface of the amygdala in emotional con...

Effects of antidepressant drugs on amygdaloid after-discharge in rats.

Effects of antidepressant drugs on the amygdaloid after-discharge induced by stimulating the amygdala in rats implanted with chronic electrodes, were investigated in correlation with anti-muricidal effects as well as neurotoxicity. Tricyclic antidepressants such as amitriptyline, imipramine and nortriptyline markedly depressed both after-discharge and muricide at doses smaller than neurotoxic d...
