The present paper summarizes functional imaging studies investigating the effects of intranasal oxytocin (OT) on brain responses to social stimuli. We aim to integrate previous research, point to unresolved issues and highlight perspectives for future studies. The studies so far have focused on identifying neural circuits underlying social information processing which are particularly sensitive...

Visual stimuli were constructed so that any given stimulus by itself appeared to be a random collection of dots. However, when 2 corresponding stimuli were superimposed by means of a 2-field tachistoscope, a 3-letter nonsense syllable was perceived. Temporal organization in perception was studied in Experiment I by varying the interval between the presentation of the 2 corresponding patterns ov...

Peripheral vision plays an important role in human visual behavior. Performance in visual search and orientation tasks in general depends largely on peripherally detected information. Among the factors affecting peripheral visual performance are the size and shape of the effective visual field. Traditional theories of visual search work on the assumption of perfectly circular or elliptical visu...

o bjectives: early diagnosis of incipient and non cavitated carious lesions is crucial for performing preventive treatments. the aim of this study was to compare the effi- ciency of three diagnostic methods of bite-wing radiography, diagnodent, and visu- al examination in diagnosing the incipient occlusal caries of permanent first molars. materials and methods:  in this diagnostic cross-section...
