[Ab] Resumo:In the present experiment, we aimed to evaluate the interactive effect of performing a cognitive task simultaneously with a manual task requiring either high or low steadiness on APRs. Young volunteers performed the task of recovering upright balance following a mechanical perturbation provoked by unanticipatedly releasing a load pulling the participant's body backwards. The postural task was performed while holding a cylinder steadily on a tray. One group performed that task under high (cylinder' round side down) and another one under low (cylinder' flat side down) manual steadiness constraint. Those tasks were evaluated in the conditions of performing concurrently a cognitive numeric subtraction task and under no cognitive task. Analysis showed that performance of the cognitive task led to increased body and tray displacement, associated with higher displacement at the hip and upper trunk, and lower magnitude of activation of the GM muscle in response to the perturbation. Conversely, high manual steadiness constraint led to reduced tray velocity in association with lower values of trunk displacement, and decreased rotation amplitude at the ankle and hip joints. We found no interactions between the effects of the cognitive and manual tasks on APRs, suggesting that they were processed in parallel in the generation of responses for balance recovery. Modulation of postural responses from the manual and cognitive tasks indicates participation of higher order neural structures in the generation of APRs, with postural responses being affected by multiple mental processes occurring in parallel.

[Ab] Resumo:Migraine is a complex neurologic disorder by which several systems of the central nervous system (autonomous system, affective, cognitive, sensoric and motoric system) may be affected on different levels. Around a fourth of the patients have migraine aura. The most common aura is the visual aura, followed by sensoric aura. But motoric deficits as well as deficits of higher cortical centers (disorders of thinking, orientation, coherence or concentration) may occur as well. In analogy with a headache calendar, an aura calendar can deliver important help in the diagnostic process of rare migraine manifestations and prevent underdiagnosis of unusual migraine manifestations. Complex migraine manifestations are diagnoses of exlusion, and a broad diagnostic work-up is warranted in order to exclude dangerous neurologic pathologies. There are no specific therapeutic recommendations, as there is a lack of randomized controlled studies.

[Ti] Título:Biological Motion Perception, Brain Responses, and Schizotypal Personality Disorder.

[Ab] Resumo:IMPORTANCE: Exploration of the ability to process socially relevant events portrayed by biological motion and to identify underlying neuronal processes can provide clues for understanding the pathophysiology of psychosis. Individuals with schizotypal personality disorder (SPD) have pervasive interpersonal deficits and odd behaviors. An understanding of the neural mechanisms involved in the perception of biological motion and the relation of activity to clinical symptoms in those mechanisms is needed. OBJECTIVE: To investigate the specificity of brain regions responsive to biological motion perception in individuals with SPD compared with healthy control individuals. DESIGN, SETTING, AND PARTICIPANTS: Twenty-one patients diagnosed as having SPD and 38 age-, sex-, and IQ-matched controls underwent event-related functional magnetic resonance imaging. The SPD group completed the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Schizotypal Personality Questionnaire for assessment of symptom severity. During scanning, all participants were required to discriminate biological from scrambled sequences of point-light animations. Data were collected from September 21. 2011, to July 13, 2013, and analyzed from March to May 2015. MAIN OUTCOMES AND MEASURES: Blood oxygenation level-dependent signals during event-related scanning and symptom severity in the SPD group. RESULTS: The 21 individuals with SPD (16 men and 5 women) and 38 controls (29 men and 9 women) had a mean (SD) age, 22.8 (3.8) vs 22.2 (2.5) years and a mean (SD) IQ, 115.00 (12.55) vs 120.24 )7.68). Brain imaging revealed the presence of neuronal activation specific to biological motion within the posterior superior temporal sulcus. However, the individuals with SPD exhibited regions of neural responsiveness within brain regions forming the reward network, which consisted of the dorsal striatum and bilateral superior medial frontal cortex (all t ≥ 2.99, P of clusters <.002). The individuals with SPD also exhibited reduced activation in the anterior and middle cingulate cortices and the lingual and superior occipital gyri, which are brain areas responsive to biological motion perception and executive control of perception (all t ≥ 3.29, P of clusters <.001). In addition, significant correlations between the hyperdopaminergic clinical symptoms and enhanced neuronal activation in the caudate nucleus and frontal cortex were observed in the SPD group (all r ≥ 0.52, P < .02). CONCLUSIONS AND RELEVANCE: Individuals with SPD display heightened activation in the neural circuitry involved in reward and decision making when viewing biological motion stimuli in addition to a positive correlation between increased blood oxygenation level-dependent signal responses related to biological motions and clinical symptoms. These findings suggest that enhanced responses arise within the reward network in individuals with SPD and are possibly related to the peculiar ways that individuals with SPD behave in social contexts.

[Ab] Resumo:In this study we have examined a group of schizophrenia patients during the understanding of irony tasks, who had normal IQ. 14 patients and 14 healthy control subjects were included, 15 irony and 15 control tasks were invertigated during an fMRI investigation. During the contextual phase patients had shown a higher activitation in different brain regions. The healthy controls had shown deactivitation during this phase, while this couldn't be seen in the patiens group. During the irony phase healthy subjects activated brain regions known as mentalisation areas, while patients didn't. Our results can support the view, that behind schizophrenia patients mentalisation deficit the contextual phase can play the central role.

[Ab] Resumo:In this study, we examined the relationships among higher brain function, trust or distrust, and gullibility in middle-aged and elderly people. It has been pointed out that the trust can be regarded the psychological frame of automatic processing in decision-makinig. The participants were 309 rural community dwellers (127-males and 182 females) whose mean age was 64.9 years old (SD = 9.9). The trust scale of Amagai (1997) and the Nagoya University Cognitive Assessment Battery were used to measure sense of trust and higher brain function, respectively. Gullibility was measured by self-report using two items. Correlation analyses showed that higher brain function positively correlated with degree of trust in others and negatively correlated with distrust. However, regression analysis demonstrated that only the relationship between category fluency and distrust was significant. Furthermore, the degree of distrust positively correlated with gullibility.

[Ab] Resumo:Neural correlation with consciousness represents a main topic of neuroscience studies. New results of consciousness researches proved that based on a coherent function in between its components the default mode network activity is the condition for awake consciousness. The subject of consciousness is self. Tasks related with the self were proving a high default mode network activity. Using connections inside the network, results which were related with self, could be considered to represent a polymodal integration system are they are participating in fine processing of the highly integrated associative information. It could be a result of the convergence of cognitive binding. There is a strong connection between the level of consciousness and praecuneal activation. It was proved that the network activity is changing during sleeping (normal condition), trauma or under drug induced altered consciousness. The default network activity can be considered as the neural correlate of consciousness. Further researches are warranted to answer the question: is the activity of the network the cause or is just accompanying the development of human consciousness?
