La région moldave, incluant aussi une partie de la Roumanie, illustre tous les stades du Paléolithique supérieur: elle débute par des industries archaïques, se poursuit à par l'Aurignacien local et surtout connaît un développement très intense durant les différents stades du Gravettien. Sa position géographique en fait une région-clef pour l'étude des rapports entre l'Europe des collines et celle des grandes plaines orientales. [less ▲]

Regional brain activity during working memory tasks

The first aim of our PET study was to replicate previous findings concerning the brain areas activated by a verbal working memory task. The second aim was to specify the neural basis of the central executive, using a task of working memory updating. Our data confirm that the lower left supramarginal gyms and premotor area are the key regions subserving short-term verbal memory processes. They also suggest that the updating memory task is related to mid-dorsolateral prefrontal activation most probably responsible for the updating function of the central executive. An unexpected, predominantly right activation occurred in the inferior parietal region during the verbal memory updating task, which we related to a visuospatial strategy used to maintain the information in short-term memory. A third purpose was to explore the brain regions activated by a nonverbal, visual memory task, and our results confirm the importance of the superior occipital gyrus in the visual short-term memory.

A regional curare test evaluation of myotonia in dogs

This paper describes a regional curare test performed in a dog suffering from myotonia and hyperadrenocorticism. The test prevented innervation to the pronator teres muscle of the left limb and allowed electrical activity to be observed in the muscle without the need for a general neuromuscular blockade; various types of spontaneous activity other than myotonic discharges were also observed. Details of the method are given and its usefulness in the evaluation of myopathies is discussed. [less ▲]

Regional Distribution and Control of Tyrosine Hydroxylase Activity in the Quail Brain

in Brain Research Bulletin (1999), 48(1), 3-17

Tyrosine hydroxylase (TH) activity, the rate-limiting step in the synthesis of catecholamines, was quantified in the preoptic area-hypothalamus of adult male Japanese quail by a new assay measuring the ... [more ▼]

Tyrosine hydroxylase (TH) activity, the rate-limiting step in the synthesis of catecholamines, was quantified in the preoptic area-hypothalamus of adult male Japanese quail by a new assay measuring the tritiated water production from 3,5-[3H]-L-tyrosine. Maximal levels of activity were observed at a 20-25 microM concentration of substrate, with more than 50% inhibition of the activity being recorded at a 100 microM concentration. TH activity was linear as a function of the incubation time during the first 20 min and maximal at a pH of 6.0. TH was heterogeneously distributed in the quail brain with highest levels of activity being found (in decreasing order) in the mesencephalon, diencephalon, and telencephalon. Given the large size of the telencephalon, this is the brain area that contains, as a whole, the highest level of enzyme activity. TH inhibitors that have been well-characterized in mammals, such as 3-iodo-L-tyrosine and L-alpha-methyl-p-tyrosine (AMPT) completely inhibited the enzyme activity at a 100 microM concentration. In mammals, the accumulation of catecholamines exerts a negative feedback control on TH activity. Similar controls were observed in the quail brain. Two inhibitors of the DOPA decarboxylase that should lead to accumulation of DOPA depressed TH activity by 60% or more, and the inhibitor of the dopamine beta-hydroxylase, fusaric acid that should cause an accumulation of dopamine, suppressed 90% of the TH activity. The addition of exogenous DOPA, dopamine, or norepinephrine to the brain homogenates also strongly inhibited TH activity, independently confirming the feedback effects of the enzyme products on the enzyme activity. These data demonstrate that TH activity in the quail brain is heterogeneously distributed and acutely regulated, as it is in mammals, by the accumulation of its products and of the derived catecholamines.
