1. A study on changes of the resting-state brain function network in patients with amnestic mild cognitive impairment
This study aimed to explore the structural and functional characteristics of the neural network of resting-state brain activities in patients with amnestic mild cognitive impairment (aMCI) by functional magnetic resonance imaging (fMRI) technology. Resting state fMRI scanning was performed on 10 clinically diagnosed aMCI patients and 10 healthy volunteers, a

2. Arterial spin labeling in patients with schizophrenia: a systematic review
Abstract Background: Neuroimaging studies are an invaluable source of information about the physiopathology of schizophrenia. Arterial spin labeling (ASL) is a new magnetic resonance technique (MRI) that is able to effectively evaluate brain function without the use of radiation. Objective: To make a systematic review of studies using ASL to compare restin

3. Inferência do tempo de atividade neural a partir do efeito BOLD em ressonância magnética funcional / Inference of neural activity time from BOLD effect in functional magnetic resonance imaging
A inferência do curso temporal da atividade neural a partir do efeito BOLD é um importante problema, ainda em aberto. A forma da curva BOLD não reflete diretamente as características temporais da atividade eletrofisiológica dos neurônios. Nessa tese, é introduzido o conceito de tempo de processamento neural (TPN) como um dos parâmetros do modelo biof

4. Voxel-based morphometry findings in Alzheimer's disease: neuropsychiatric symptoms and disability correlations - preliminary results
INTRODUCTION: The role of structural brain changes and their correlations with neuropsychiatric symptoms and disability in Alzheimer's disease are still poorly understood. OBJECTIVE: To establish whether structural changes in grey matter volume in patients with mild Alzheimer's disease are associated with neuropsychiatric symptoms and disability METHODS: Nin

5. Brain activation for reading and listening comprehension: an fMRI study of modality effects and individual differences in language comprehension
The study compared the brain activation patterns associated with the comprehension of written and spoken Portuguese sentences. An fMRI study measured brain activity while participants read and listened to sentences about general world knowledge. Participants had to decide if the sentences were true or false. To mirror the transient nature of spoken sentences

6. Face perception in its neurobiological and social context
Significant advances in the understanding of processes involved in face perception have been achieved. This study aims to review the literature of face perception in neurobiological and social contexts. The review focused on the mechanisms of mediation of face perception by neural substrates, and discussed some of the social signals provided by faces. We sho

7. Avaliação do tratamento de depressão em pacientes com doença de Parkinson através de ressonância magnética funcional / Evaluation of depression treatment in Parkinsons disease patients with functional magnetic resonance
The neural circuitry underlying depression in patients with Parkinsons disease (PD) is unknown, let alone the treatment effects of antidepressant therapy. Neuroimaging methods can give insights into the pathogenesis of depression and also in the mechanisms of action related to specific treatment choice. In order to evaluate differences between PD patients wi

8. O fenÃmeno muitas faces: estudo comparando a percepÃÃo do fenÃmeno quando utilizados estÃmulos de face e cadeira
The Multiple Faces Phenomenon, is perceived when printed faces are observed at the visual peripheral field. This phenomenon is characterized by perception of changes in the face, such as, movements and variations of facial expression (category 1), and new characteristics or perception of other faces with different identities (category 2). The current study c

9. Lingual and fusiform gyri in visual processing: a clinico-pathologic study of superior altitudinal hemianopia.
A macular-sparing superior altitudinal hemianopia with no visuo-psychic disturbance, except impaired visual learning, was associated with bilateral ischaemic necrosis of the lingual gyrus and only partial involvement of the fusiform gyrus on the left side. It is suggested that bilateral destruction of the lingual gyrus alone is not sufficient to affect compl

10. Emotional attention in acquired prosopagnosia
The present study investigated whether emotionally expressive faces guide attention and modulate fMRI activity in fusiform gyrus in acquired prosopagnosia. Patient PS, a pure case of acquired prosopagnosia with intact right middle fusiform gyrus, performed two behavioral experiments and a functional imaging experiment to address these questions. In a visual

11. Naming difficulties in alexia with agraphia for kanji after a left posterior inferior temporal lesion.
The case is described of a patient with alexia and agraphia for kanji, and severe anomia after a subcortical haemorrhage in the left posterior inferior temporal area. Magnetic resonance imaging at four months after onset showed a lesion in the inferior temporal and fusiform gyri, extending from the temporo-occipital junction toward the anterior third of the

12. Dissociable prefrontal brain systems for attention and emotion
The prefrontal cortex has been implicated in a variety of attentional, executive, and mnemonic mental operations, yet its functional organization is still highly debated. The present study used functional MRI to determine whether attentional and emotional functions are segregated into dissociable prefrontal networks in the human brain. Subjects discriminated
