Abstract: An information processing system visualizes brain states to optimize rehabilitation programs for rapid feedback of their effects to a patient and healthcare staff, to thereby promote the efficiency of rehabilitation. An embodiment of the system includes: a storage section that stores test-result brain-state relationship information associating results of activities of multiple examinees subjected to predetermined tests with brain states of the examinees; an input section that accepts a first test result as the result of the activity of a first examinee subjected to the predetermined tests; a control section that estimates the brain state from the first test result on the basis of the test-result brain-state relationship information; and an output section that outputs the estimated brain state.

Abstract: Provided herein is a technique for effectively and quantitatively evaluating the symptom improving effect of a treatment given to a subject (patient). The invention provides a technique for diagnosing, evaluating, monitoring, and predicting drug efficacy in individuals (patients) with possible mental disorders such as ADHD, autism, and depression. Specifically, patient's data are simultaneously analyzed using several variables, such as biological measurements (e.g., brain activity measurements) and cognitive performance assessments, involving, for example, a patient (dependent variable), a medication type and dose (independent variables), a diagnosis profile score (DSM) and a rating scale (manifest variables), and an efficacy index (a predictor variable of a future treatment).

Abstract: An electromagnetic wave processing system mounted on a spacecraft including a plurality of antennas includes: a measurement apparatus configured to process measurement signals of electromagnetic waves acquired by the plurality of antennas; an attitude detection apparatus configured to detect an attitude of the spacecraft; a rotation control apparatus configured to control rotation of the spacecraft; and a calculation apparatus. The rotation control apparatus rotates the spacecraft about a center of gravity around a plurality of rotational axes with respect to an inertial space. The measurement apparatus performs measurement at a plurality of attitudes changed by the rotation. The calculation apparatus calculates an intensity distribution of electromagnetic waves acquired by the plurality of antennas using an interference waveform obtained by multiplying measurement signals obtained from different antennas in the measurement signals obtained at the plurality of attitudes.
