1. Detection of movement intention using EEG in a human-robot interaction environment
Introduction : This paper presents a detection method for upper limb movement intention as part of a brain-machine interface using EEG signals, whose final goal is to assist disabled or vulnerable people with activities of daily living. Methods EEG signals were recorded from six naïve healthy volunteers while performing a motor task. Every volunteer remain

2. Interaction between affordance and handedness recognition: a chronometric study
The visualization of tools and manipulable objects activates motor-related areas in the cortex, facilitating possible actions toward them. This pattern of activity may underlie the phenomenon of object affordance. Some cortical motor neurons are also covertly activated during the recognition of body parts such as hands. One hypothesis is that different subpo

3. PRODUÇÃO DE ALTERIDADE: A EXPERIÊNCIA DO MINOTAURO / PRODUCTION OF OTHER: THE MINOTAUR`S EXPERIENCE
The objective of this essay is to analyse the representation issues surrounding the themes of the Bull, Bullfighting and the Minotaur in three specific instances. The first instance is in Surrealism, the early 20th century avant-garde art movement. The Bull and the Minotaur are revisited and taken as object of representation by different painters during this

4. Alterações neurorradiológicas em pacientes com Síndrome de Kallmann: estudos por Ressonância Magnética / Neuroradiologic changes in Kallmann Syndrome: studies with Magnetic Resonance Imaging.
A Síndrome de Kallmann (SK), associação entre hipogonadismo hipogonadotrófico e distúrbio olfatório (hiposmia ou anosmia), é causada por uma deficiência da migração neuronal que envolve as células produtoras do hormônio liberador de gonadotrofinas e os neurônios olfatórios, com origem embriológica comum. O primeiro gene descrito, KAL1, codific

5. Recognition of hand shape drawings on vertical and horizontal display
The visual recognition of body parts activates somato-motor representations in the brain. In the present study, we investigate the influence of the plane in which hand drawings are displayed (Vertical or Horizontal) on mental rotations evoked by a handedness recognition task. Sixteen right-handed volunteers participated in an experiment where the task was to

6. Efeitos da Imagem Mental na Reabilitação da Função Motora do Membro Superior na Hemiplegia Após-Acidente Vascular Encefálico
The goal of this study was to investigate the effects of mental imagery in response to mirror therapy in rehabilitation of the motor function in the upper extremity in hemiplegia by stroke. Twenty volunteers both sexes were selected, by simple random, from communitary services via advertisements and physician referral of the city of Santa Maria/RS. The inclu

7. Construção e análise de desempenho de um fogão solar à concentração utilizando dois focos para cozimento direto
A model of a solar oven with a reflective surface composed of two mirror segments is presented, constituting a two semi-parabolic surfaces made of fiberglass, applied on a ceramic mold, intended to be used in residential and commercial cooking. The reflective surface of the semi-parable is obtained with the use of multiple plain segments of 2 mm wide mirrors

8. Brain plasticity induced by motor training : a study with professional typist / Plasticidade cerebral associada ao treino motor prolongado : um estudo com digitadores profissionais
Background: Long-term training of specific motor tasks is associated with automatic execution of movements. Functional adaptation induced by training results in performance improvement. It is not yet fully understood whether functional adaptation is reflected by plasticity changes in brain structure. Objectives: We aimed to investigate the presence and degre

9. Fala instituinte do discurso mitico Guarani Mbya
The main hypothesis that conducts this analysis assumes that a myth plays a ro11 of a founder discourse. However, it is not enough just to assume this statement, it is necessary to demonstra te the operating discoursive mechanisms of the myth, as well as to show in which circumstances and in which ways its character of foünding discourse is manifested in th

10. Central motor pathways in patients with mirror movements.
Central motor pathways were investigated in three patients with congenital mirror movements using magnetic motor cortex stimulation. Response thresholds, amplitudes and latencies were normal. The projection of the corticomotoneuronal pathways was assessed by placing the coil over the vertex and comparing the size of responses in the first dorsal interosseous

11. Role of the ipsilateral motor cortex in mirror movements.
The mechanism of mirror movements in two patients was investigated; one with congenital mirror movement, the other with schizencephaly. Transcranial magnetic stimulation on one side elicited motor evoked potentials (MEPs) in their thenar muscles on both sides with almost the same latencies, minimal thresholds, and cortical topographies. During voluntary cont

12. Congenital mirror movements.
In this report are described seven patients assessed clinically and neuropsychologically in whom mirror movements affecting predominantly the hands occurred as a congenital disorder. These mirror movements, representing a specific type of abnormal synkinesia, may arise as a hereditary condition, in the presence of a recognisable underlying neurological abnor
