A large population of immature neurons is present in the ventromedial portion of the adult primate amygdala, a region that receives substantial direct projections from the hippocampal formation. Here, we show the effects of neonatal (n = 8) and adult (n = 6) hippocampal lesions on the populations of mature and immature neurons in the paralaminar, lateral, and basal nuclei of the adult monkey am...

Anatomic descriptions of amygdaloid lesions resulting in hyperphagia and obesity in rats, cats, and dogs have been inconsistent and often contradictory, frequently resulting in failures to replicate. The present study attempted to reconcile these differences by examining common areas of overlap among differently placed lesions in female rats. Small bilateral lesions of the most posterodorsal as...

introduction: the role of adenosine a1 receptors of the entorhinal cortex on amygdaloid kindled seizures was investigated. material and methods: animals were kindled by daily electrical stimulation of amygdala. in the full kindled animals, n6-cyclohexyladenosine (cha; 0.1, 1 and 10 mm), an adenosine a1 receptor agonist, and 8-cyclopenthyle 1,3-dimethylexanthine (cpt), an adenosine a1 receptor a...

Painful stimuli evoke pain sensation and unpleasant emotional feelings. Recent studies demonstrated that the anterior cingulate cortex (ACC) and amygdala play a crucial role in pain-related negative emotion using a rat formalininduced conditioned place aversion (F-CPA) model, a nociceptor-driven, associative avoidance-learning assay, which was considered as a direct reflection of negative emoti...

To investigate emotion recognition in amyotrophic lateral sclerosis (ALS) patients without cognitive/behavioral deficits and its relationship with the integrity of basal ganglia, hippocampus amygdala.

introduction: the role of adenosine a1 receptors of the amygdala on entorhinal cortex kindled seizures was investigated. material and methods: animals were kindled by daily electrical stimutation of entorhinal cortex. in the full kindled animals, n6-cyclohexyladenosine (cha 10, 50, 100, 500óm), an adenosine a1 receptor agonist and 8-cyclopentyl- 1, 3, dimethylxanthine (cpt, 10, 20 óm), an adeno...

introduction: considering the antiepileptogenic effects of repeated transcranial magnetic stimulation (rtms), the effect of rtms applied during amygdala kindling on spontaneous activity of hippocampal ca1 pyramidal neurons was investigated. materials and methods: a tripolar electrode was inserted in basolateral amygdala of male wistar rats. after a recovery period, animals received daily kindli...

effects of intra-central amygdala administration of l-arginine, a nitric oxide precursor, and ng-nitro-l-arginine methyl-ester (l name), a nitric oxide synthase inhibitor, on the morphine-induced sensitization and also on the expression of morphine-induced place conditioning in rats were studied. subcutaneous (s.c.) administration of morphine (2.5, 5 and 7.5 mg/kg) induced place conditioning. r...

abstract   squamous cell carcinoma (scc) is the most common malignant tumors of oral cavity. the ratio of men to women is about 2: 1. generally, it   is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. gingiva is one of the less common sites of oral squamous cell carcinoma (oscc). due to the variable clinical and behavioral presentations, it c...

background: the optimal strategy in percutaneous coronary intervention (pci) for coronary artery bifurcation lesions has yet to be agreed upon. we compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (timi) - iii, with a strategy for intervention in both the main vessel and the side branch (mv + sb...
