Os déficits sensoriais têm sido atribuídos a alterações vasculares e da função de fotorreceptores (Greenstein e cols., 2000; Lieth e cols., 2000). Contudo, poucas conclusões acerca dos mecanismos fisiopatológicos têm sido obtidas. Este trabalho teve por objetivo identificar - em pacientes diabéticos tipo 2 com fundo de olho normal - possíveis alterações na visão de cores e sensibilidade ao contraste cromático e acromático e correlacionar os prejuízos sensoriais com a função eletrofisiológica da retina. A avaliação sensorial foi feita utilizando o Teste de Cores de Cambridge e o teste de sensibilidade ao contraste Psycho (Ventura e cols., 2003a, Ventura e cols., no prelo) e a função eletrofisiológica foi avaliada usando o eletrorretinograma de campo total (ERG). Os resultados dos pacientes diabé...

Odors can facilitate or impair the identification of facial expressions, and apparently its hedonic valence plays an important role. However, it was also demonstrated that the presentation of happiness and disgust faces can influence the emotional appraisal of odorants, indicating a bilateral influence in this phenomenon. Hence, it’s possible that odor influences on emotional categorization vary depending on the intensity of expressions. To investigate this hypothesis, we performed an emotion recognition task using facial expressions of five emotional categories (happiness, fear, disgust, anger and sadness) with ten different intensities. Thirty-five participants completed four blocks of the task, each with a different olfactory condition, and we found that odorants’ effects varied according to the facial expressions intensity. Odorants enhanced...
