| Research Abstract |
This near infrared spectroscopy(NIRS) research investigated that 1) the neural activity in infant's mother's face recognition, and that 2) the hemodynamic responses to happy and angry facial expressions in infants.
1) The hemodynamic responses in the right temporal cortex increased for strangers 'faces. By contrast, the presentation of mother's face elicited great hemodynamic responses in the bilateral temporal cortex. The findings imply that the probable presence of cortical specialization for the mother's face in infants may be firmly established by the age of 7 to 8 months.
2) The left temporal area was significantly activated relative to the baseline when infants looked at happy faces, while the right temporal area was significantly activated for angry faces. The results suggested that the different hemodynamic responses between the perception of positive and negative expressions in infants is related to the different biological meanings of positive and negative facial expressions.
