1. Electrophysiological investigation of the functional overlap between semantic and equivalence relations
Recent research using the event-related potential (ERP) technique has shown that equivalence relations have properties similar to genuine semantic relations. This study aimed to advance electrophysiological investigations of the functional overlap between semantic and equivalence relations. The N400 component, an index of semantic processing, was used to mea

2. Discriminações simples simultâneas e sucessivas - na formação de classes funcionais / Simple simultaneous and successive discriminations and the emergence of functional classes
Functional classes can be established thorough simple discrimination and repeated reversals training. However, successive reversals necessarily involve experience with the occurrence of errors, which may interfere with class formation. A previous study using this procedure indeed generated a pattern of errors that seemed to be related to the position of the

3. Formação de classes funcionais de estímulos musicais
Uma abordagem comportamental da música considera a ação musical como comportamento e a música como estímulo, produto dessa ação. O objetivo geral aqui proposto foi o de verificar o efeito do treino discriminativo sobre a formação de classes funcionais de melodias em andamentos e modos diferentes. Participantes: 9 estudantes do segundo período da Gr

4. Aspectos do envelhecimento cerebral e função cognitiva em modelo experimental animal e estudo de mecanismos de neurodegeneração em cultura celular
The two phenomena, biological and behavioural, approached in the present work are brain aging and spatial memory. Several studies, comparative and experimental, have shown that aged subjects present significantly impaired performances in different types of cognitive tasks. It is also known that contradictions in literature exist in relation to consequences o

5. The emergence of condictional relations among stimuli as the result of a simple simultaneous discrimination trining of pairs of stimuli / A emergência de relações condicionais entre estímulos como resultado de treino de pares de discriminações simples simultâneas
Classes de estímulos têm sido definidas por um conjunto de determinadas propriedades que compartilham. Analistas do comportamento têm estudado procedimentos para produzir e para identificar ou avaliar a formação de classes de estímulos e mais recentemente têm proposto que há mais de um tipo de classe de estímulos, por exemplo, classes de estímulos

6. A hipertensão arterial refrataria : caracterização fenotipica, avalliação cardiovascular morfo-funcional e correlação com polimorfismos geneticos de sistema renina-angiotensina e da sintase endotelial do oxido nitrico / Refractory hypertension : phenotypic characterization, cardiovascular morpho-functional assesssment and correlation with the renin-angiotensin-aldosterene and endothelial nitric oxide synthase gene polymorphisms
Refractory hypertension (HAR) is defined, according to the Seventh Joint National Committee (JNC VII), when the systolic arterial pressure remains above 140 mmHg and the diastolic arterial pressure above 90 mmHg even when taking three or more classes of anti-hypertensive agents including full-dose of a diuretic and the other agents at sub maximum doses with

7. The effects of neonatal median nerve injury on the responsiveness of tactile neurones within the cuneate nucleus of the cat.
1. The capacity of cuneate neurones to attain normal functional properties following neonatal median nerve injury was investigated with single neurone recording in anaesthetized cats, 12-24 months subsequent to a controlled crush injury. Effectiveness of the peripheral nerve injury was confirmed by the abolition of the median nerve compound action potential

8. Religion as Schedule-Induced Behavior
In this article, I argue that a class of religious behaviors exists that is induced, for prepared organisms, by specific stimuli that are experienced according to a response-independent schedule. Like other schedule-induced behaviors, the members of this class serve as minimal units out of which functional behavior may arise. In this way, there exist two cla

9. Molecular cloning and characterization of human caspase-activated DNase
Caspase-activated DNase (CAD) cleaves chromosomal DNA during apoptosis. Here, we report isolation of two classes of human CAD cDNAs from a human KT-3 leukemic cell cDNA library. One class of cDNA encoded a protein comprising 338 amino acids, which showed a marked similarity to its murine counterpart. In vitro transcription and translation of this cDNA result

10. X and Y cells in the lateral geniculate nucleus of macaque monkeys.
1. Cells of the lateral geniculate nucleus (l.g.n.) in macaque monkeys were sorted into two functional groups on the basis of spatial summation of visually evoked neural signals. 2. Cells were called X cells if their responses to contrast reversal of fine sine gratings were at the fundamental temporal modulation frequency with null positions one quarter of a

11. Increase in plasma concentrations of cardiodilatin (amino terminal pro-atrial natriuretic peptide) in cardiac failure and during recumbency.
Plasma concentrations of cardiodilatin, the peptide sequence at the amino terminal of the pro-atrial natriuretic peptide, in 17 normal subjects ranged from 59 to 202 (mean 118 (SEM) (9] pmol/l. Recumbency increased the mean (SEM) concentration to 160 (13) pmol/l. The plasma concentration of cardiodilatin in 24 patients with congestive cardiac failure was muc

12. The analysis of large-scale gene expression correlated to the phase changes of the migratory locust
The migratory locust is one of the most notorious agricultural pests that undergo a well known reversible, density-dependent phase transition from the solitary to the gregarious. To demonstrate the underlying molecular mechanisms of the phase change, we generated 76,012 ESTs from the whole body and dissected organs in the two phases. Comparing 12,161 unigene
