1. Tinnitus Neural Mechanisms and Structural Changes in the Brain: The Contribution of Neuroimaging Research
Introduction Tinnitus is an abnormal perception of sound in the absence of an external stimulus. Chronic tinnitus usually has a high impact in many aspects of patients' lives, such as emotional stress, sleep disturbance, concentration difficulties, and so on. These strong reactions are usually attributed to central nervous system involv

2. Efeitos do envelhecimento sobre o sistema nitrérgico dos núcleos da base em humanos
Nitric oxide (NO) is a gaseous molecule that plays a role in a number of physiologic processes. The available evidence suggests that NO is a major neurotransmitter involved in motor control and emotion/behavior modulation. To investigate the distribution and morphology of the nitrergic system in human basal nuclei, we studied samples from the striatum, globu

3. Neural regulation of the stress response: glucocorticoid feedback mechanisms
The mammalian stress response is an integrated physiological and psychological reaction to real or perceived adversity. Glucocorticoids are an important component of this response, acting to redistribute energy resources to both optimize survival in the face of challenge and to restore homeostasis after the immediate challenge has subsided. Release of glucoc

4. Um algoritmo de segmentação de íris em tempo real / An iris segmentation algorithm in real time
Iris segmentation is one of the crucial operations involved in iris recognition. Accurate iris segmentation is fundamental for the success and precision of the subsequent feature extraction and recognition, and consequently the high performance level of the iris recognition system. Most iris segmentation approaches proposed in the literature require highly c

5. Atenção visual em crianças com migrânea: um estudo comparativo controlado / Visual attention in children with migraine: a controlled comparative study
Objective: To evaluate the visual attention of children with migraine and compare to the headache free control group. Method: 30 children with migraine, with (n=5) and without aura (n=25), which fulfill the gInternational Headache Society (ICHD-II, 2004)h criteria, 15 female, ages 8 to 12 years and 11 months (average=10.8 }1.5 years), with an average of 5.8

6. Study of the use of conceptual map in promoting meaningful learning of the neuroscience content in graduation / Estudo do uso de mapa conceitual na promoção de aprendizagem significativa de conteúdo de neurociência na graduação
The study of cognitive processes provide a promising scenario to research aimed at better understanding of how the functioning of the brain may promote the education, enabling the development of new theories and approaches that encourage learning. This work will mainly occurs as the acquisition, storage, processing and retrieval of knowledge from the viewpoi

7. Patterns of brain functioning in healthy volunteers before and after the use of antidepressant: a study of functional magnetic resonance imaging during emotional induction through visual stimulation / Padrões de funcionamento cerebral em voluntários saudáveis antes e após o uso de antidepressivo: estudo de ressonância magnética funcional durante indução emocional através de estimulação visual
INTRODUÇÃO: O processamento emocional pelo cérebro humano tem sido atualmente investigado através do uso de ressônancia magnética funcional (RMf). A RMf possibilita o estudo in vivo e não invasivo de mudanças na atividade cerebral regional em voluntários humanos saudáveis. O processamento emocional pode ser modulado através do uso de antidepressiv

8. Temporal evaluation of c-fos expression in amygdaloid and hypothalamic areas following experimental tooth movement in rats / Avaliação temporal da expressão da proteína FOS em áreas amigdalóides e hipotalâmicas após movimentação dentária experimental em ratos
In the accomplishment of the orthodontic treatment, it is described that the pain happens immediately after the application of orthodontic forces and disappears after few days. Regarding the neural pathways involved in the sensorial mediation of the orthodontic movement (OM) few are the studies that approach this theme, and in the last decades solid founds d

9. Sensibilidade diferencial aos efeitos comportamentais induzidos por etanol e sobre a expressão de c-Fos e Egr-1, entre camundongos adultos e adolescentes. / Differential sensitivity to ethanol-induced behavioral effects and c-Fos /Egr-1 expression between adolescent and adult mice.
The transition from adolescence (ADOLESC) into adulthood (ADULT) is characterized by behavioral maturation, as well as of structures and systems of CNS. This study investigated the behavioral effects of acute and repeated administration of EtOH (2,0 g/kg) in ADULT and ADOLESC mice, as well as the c-Fos and Egr-1 expression induced by EtOH in distinctive brai

10. Efeitos da clorfeniramina na aprendizagem, memória e ansiedade de teleósteos submetidos à ablação telencefálica.
The teleost telencephalon provides a good opportunity for studying the function of the vertebrate limbic system because it is simple and present homologies to the limbic structure of higher vertebrates, with hippocampus and amygdala. These animals shows only one area of projection to the telencephalon (Ekström et al., 1995), which has been well preserved th

11. Role of the hypothalamic pituitary adrenal axis in the control of the response to stress and infection
The release of adrenocorticotropin (ACTH) from the corticotrophs is controlled principally by vasopressin and corticotropin-releasing hormone (CRH). Oxytocin may augment the release of ACTH under certain conditions, whereas atrial natriuretic peptide acts as a corticotropin release-inhibiting factor to inhibit ACTH release by direct action on the pituitary.
