Time course MRI data is acquired from the hippocampal region of the brain and processed to produce two indices that are a measure of the functional connectivity between locations therein. The light source unit includes a first light source emitting red light, a second light source emitting green light and a third light source emitting blue light. In a first mode, the voice commands from the caller and the pre-recorded messages of the DTMF-driven system are echo cancelled. The pixel electrode of the first liquid crystal element is electrically connected to a pixel electrode of the second liquid crystal element through the second switch and the first resistor. A user configuration device selects the values for the stored configuration information. The inspection apparatus comprises means for supplying an AC signal alternately to either one of the finger pattern segments and both the finger pattern segments and the discrete patterns while maintaining the other at a ground potential, and sensors 131, 132, 133 for detecting the AC signal disposed in the edge region.
