The authors report four cases in which severely damaged human remains were identified by mitochondrial DNA (mtDNA) sequencing. Degraded DNA was extracted from highly adipoceratous tissues using the phenol-chloroform method and polymerase chain reaction amplified for sequencing of two hypervariable regions, hypervariable region 1 and hypervariable region 2, of mitochondrial DNA. They also sequenced these regions of blood samples that were obtained from the presumptive mother or sister of the human remains. The sequencing results were compared with each other and with the Anderson's sequence. It was concluded from the sequence data that a lower part of a body in case 1 and some organs in case 2 were from the same woman, and a human head in case 3 and a female body in case 4 were from the relative of a presumptive mother and a sister, respectively.

The affective primacy hypothesis asserts that positive and negative affective reactions can be evoked with minimal stimulus input. This phenomenon has been tested using subliminal affective priming technique, however, these techniques are not robust enough and have not been fully explored. The aim of this study was to clarify existence of the affective primacy and the underlying mechanism by a neuroimaging method using event related functional magnetic resonance imaging (fMRI). Fourteen participants were scanned during a task in which they evaluated presented facial expressions of "anger, " "neutral, " or "happiness." Target stimuli were faces expressing weak and ambiguous anger expressions, which were presented just after a presentation of either (1) faces with strong anger expressions as affective stimuli, neutral faces, or a non-face object; or (2) flash as a control stimuli of 35ms duration. Processing of facial expressions in each condition commonly increased regional blood oxygenation level-dependent (BOLD) activity in the bilateral inferior frontal gyrus and left anterior cingulate gyrus. We identified the anterior part of anterior cingulate gyrus showed significant activation in the anger prime condition compared with the other three prime conditions. This suggests that the affective priming effect engendered especially in the anterior cingulate cortex. This suggests that a part of the neurophysiological substrates that underlies the subliminal affective priming has been identified.

An event-related brain potential (ERP) study investigated how different processing stages involved in categorization of facial expression are reflected by ERP modulations, and how ambiguity of facial expressions influence such effects. ERPs were recorded in response to facial expressions in which ambiguity was controlled by morphing techniques. Fifteen participants labeled positive or negative emotion expressed by face. The labeling task was a forced choice two categories. Each trial lasted 6.5s (0.5s of presentation, followed by a 6s interval of scrambled faces).<BR>The ambiguous expression gave rise to N480 ms component with frontocentral and bilateral temporal electrodes; the onset of N480 component was much later in temporal than frontcentral. These findings suggest that activity in both frontocentral and temporal region vary with ambiguity of facial expressions in the categorization process.
