“…The FFA is involved in face perception, and is known to respond actively to face stimuli [17][18][19][20][21] . However, the spatial conservation and transmission of activity-related information has never been observed.…”

Modern neuroimaging represents three-dimensional brain activity, which varies across brain regions. It remains unknown whether activity within brain regions is organized in spatial configurations to reflect perceptual and cognitive processes. We developed a rotational crosscorrelation method allowing a straightforward analysis of spatial activity patterns for the precise detection of the spatially correlated distributions of brain activity. Using several statistical approaches, we found that the seed patterns in the fusiform face area were robustly correlated to brain regions involved in face-specific representations. These regions differed from the non-specific visual network meaning that activity structure in the brain is locally preserved in stimulation-specific regions. Our findings indicate spatially correlated perceptual representations in cerebral activity and suggest that the 3D coding of the processed information is organized in locally preserved activity patterns. More generally, our results provide the first demonstration that information is represented and transmitted as local spatial configurations of brain activity.

“…O seu reconhecimento favorece o comportamento social humano (de Souza, Feitosa, Eifuku, Tamura, & Ono, 2008;Spikman et al, 2013) e a sua consequente adaptação (Darwin, 1872(Darwin, /2000Spikman et al, 2013). Dessa forma, ao discriminar as emoções, o indivíduo escolhe a melhor forma de interagir com o outro, promovendo uma comunicação interpessoal efi caz (Hargrave, Maddock, & Stone, 2002;McLellan, Johnston, Dalrymple-Alford, & Porter, 2008;Spikman et al, 2013;Weigelt, Koldewyn, & Kanwisher, 2011).…”

“…As principais estruturas relacionadas ao funcionamento de expressões faciais são a amígdala, o córtex pré-frontal medial e o córtex fusiforme (Haxby, Hoffman, & Gobbini, 2002;McLellan et al, 2008). O processamento emocional tem como substrato neural o sulco temporal superior (STS; de Souza et al, 2008;Haxby et al, 2002), o estriado ventral, o cíngulo anterior e a ínsula. Assim, a ativação do cíngulo anterior e do cíngulo subcaloso está associada à tristeza; a amígdala relaciona-se ao reconhecimento do medo e da alegria (Choleris, Kavaliers, & Pfaff, 2008;Haxby et al, 2002;Kipps, Duggins, McCusker, & Calder, 2007;Sato et al, 2002); os gânglios da base e a ínsula favorecem o reconhecimento do nojo (McLellan et al, 2008); o giro fusiforme, o giro temporal superior direito, o giro parahipocampal, o córtex cingulado e o cerebelo relacionam-se à expressão de surpresa (Yoshimura, Kawamura, Masaoka, & Homma, 2005); o córtex órbito-frontal (Blair & Cipolotti, 2000), o giro cingulado anterior e a amígdala (Haxby et al, 2002;Lee, Sun, Leung, Chu, & Keysers, 2013;Sato et al, 2002;Tessitore et al, 2002;Wright, Dickerson, Feczko, Negeira, & Williams, 2007) são responsáveis pelo processamento da raiva.…”

“…No caso da Doença de Alzheimer (DA), estudos (Burnham & Hogervorst, 2004;Celone et al, 2006;de Souza et al, 2008;Drapeau, Gosselin, Gagnon, Peretz, & Lorrain, 2009;Guaita et al, 2009;Kohler et al, 2005;Lee et al, 2013;McLellan et al, 2008;Perry et al, 2001;Werheid & Clare, 2007) mostraram que a amígdala e o lobo temporal do cérebro são afetados, causando prejuízos nas memórias semântica e episódica e no reconhecimento facial e das expressões emocionais da face. Consequentemente, há uma diminuição nas interações sociais, predispondo o idoso com DA a um declínio funcional posterior (Lee et al, 2013).…”

ResumoA literatura vem discutindo acerca da percepção de emoções faciais evidentes em idosos com Doença de Alzheimer (DA). Alguns autores sugerem que os défi cits apresentados são decorrentes de problemas visuoespaciais; outros sugerem que são por difi culdades no processamento das emoções; e há os que defendem que esse défi cit perceptivo é secundário à evolução da demência. Esta pesquisa buscou investigar os aspectos neuropsicológicos da expressão emocional facial, por meio da aplicação da Escala de Inteligência Wechsler para Adultos-III (WAIS-III) e de um programa de computador desenvolvido pelo Laboratório de Psicobiologia denominado Teste de Percepção de Expressões Faciais (TEPEF), que avalia a percepção de faces emocionais em idosos. Os resultados sugerem que o WAIS-III foi sensível para a diferenciação entre os grupos experimental e controle, mas apresentou pouca especifi cidade. O TEPEF apresentou consistência para avaliar as expressões faciais de alegria, tristeza, nojo, surpresa e raiva. Além disso, ele mostrou que a percepção de alegria em idosos com DA em fase moderada está relativamente preservada. Conclui-se, portanto, que os prejuízos relacionam-se às emoções negativas evidenciadas pela percepção das faces emocionais, demandando supervisão continuada para os idosos com essas alterações. Palavras-chave: Doença de Alzheimer, face, percepção visual. AbstractLiterature has been discussing the perception of emotional facial expressions in elderly suffering from Alzheimer's Disease (AD). Some authors suggest that defi cits occur due to visuospatial problems; others suggest that the diffi culty is related to emotional processing; still others argue that this perceptive defi cit is secondary to dementia evolution. This study aimed to investigate the neuropsychological aspects of the perception of facial emotional expression by applying the Wechsler Adult Intelligence Scale-III (WAIS-III) test, as well as a software named Perception Test of Facial Emotional Expressions (TEPEF), which analyzes the perception of emotional faces by the elderly. The results suggest that WAIS-III was sensible in discriminating the differences between experimental and control groups, but presented little specifi city. The TEPEF presented consistency to evaluate facial expressions of happiness, sadness, disgust, surprise and anger. Furthermore, it showed that the perception of happiness in the elderly with mild AD is relatively preserved. The expressions more easily perceived -such as happiness and sadness -had correlations with few WAIS-III subtests. Therefore, the study concluded that the losses are related to negative emotions evidenced by the perception of emotional faces, which requires continued supervision for the elderly with these changes.

“…Face recognition, facial emotional expression, and the detection of a fixed gaze direction play crucial roles in non-verbal communication. The face is important in the process of identifying and recognizing peers and can provide different kinds of information, such as familiarity or the nature of the emotion that is being felt (De Souza, Feitosa, Eifuku, Tamura, & Ono, 2008).…”

Down syndrome (DS) is one of the most common chromosomal abnormalities. Delays in cognitive development are found in the first years of life. As years pass, it may turn into intellectual deficiencies that unfold into several aspects, including difficulty recognizing emotional facial expressions. The present study investigated the recognition of six universal facial emotional expressions in a population of children aged 6-11 years who were divided into two groups: DS group and typically developing children (TDC) group. We used the Perception Test of Facial Emotional Expressions (Teste de Percepção de Emoções Faciais; TEPEF) and Wechsler Intelligence Scale for Children (WISC-III) and found that children with DS presented alterations in the recognition of expressions of disgust, surprise, and fear, whereas the recognition of happiness, sadness, and anger was maintained at a level comparable to the TDC group. Participants with DS presented significant positive correlations between sadness and Picture completion, Mazes, Arithmetic, Vocabulary, Digits, Verbal IQ, Verbal Comprehension Index, and Working Memory Index. All other facial expressions showed significant negative correlations with the Intelligence Quotient and WISC-III factorial index subtests. Absence of correlations was found among the TEPEF's six facial expressions and Information, Coding, Symbols, and Working Memory Index. The contribution of this study is related to understanding the characteristics of the recognition of facial emotions in children with DS, an important component of social relationships with their peers, schools, and families.
