A wireless base station (1) includes a wakeup device (13) and a main device (14). When the main device (14) is in a sleep mode, the wakeup device (13) is connected to the antenna (11). Then, when the wakeup device (13) receives a wakeup signal for activating the wireless base station (1) from a terminal device assigned to the wireless base station (1) in a communication band used for wireless communication with the terminal device and when the information for identifying a wireless base station to be activated contained in the received wakeup signal is identical with the identification information of the wireless base station (1), the wakeup device (13) outputs a driving signal to the main device (14). The main device (14) transitions from the sleep mode to an operating mode in response to the driving signal from the wakeup device (13).

[Object] An object is to provide a brain activity measuring apparatus and a brain activity measuring method that can precisely ensure reproducibility of measurements for a plurality of measurements made separately for a number of times using functional magnetic resonance imaging. [Solution] In an MRI apparatus 10, a data processing unit 32 determines rigid transformation between an original tomographic image obtained in a past measurement and stored in a storage unit 36 and a pilot tomographic image obtained in a present imaging session such that mutual information between the original and pilot tomographic images is locally maximized; and based on a parameter of the determined rigid transformation, position and direction of a slice image of the tomographic image in the present imaging session are corrected.

Provided is a brain activity training apparatus for training to cause a change in correlation of connectivity among brain regions, utilizing measured correlations of connections among brains regions as feedback information. From measured data of resting-state functional connectivity MRI of a healthy group and a patient group (S102), correlation matrix of degree of brain activities among prescribed brain regions is derived for each subject. Feature extraction is executed (S104) by regularized canonical correlation analysis on the correlation matrix and attributes of the subject including a disease/healthy label of the subject. Based on the result of regularized canonical correlation analysis, by discriminant analysis through sparse logistic regression, a discriminator is generated (S108). The brain activity training apparatus feeds back a reward value to the subject based on the result of discriminator on the data of functional connectivity MRI of the subject.

Provided is a method of analyzing brain activities for realizing a biomarker for neurological/mental disorder, based on brain function imaging. From measured data of resting-state functional connectivity MRI of a healthy group and a patient group, correlation matrix (80) of degree of brain activities among prescribed brain regions is derived for each subject. Feature extraction is executed by regularized canonical correlation analysis (82) on the correlation matrix (80) and attributes of the subject including a disease/healthy label of the subject. Based on the result of regularized canonical correlation analysis, by discriminant analysis (86) through sparse logistic regression, a discriminator (88) is generated.

[Problem] To provide a calibration apparatus capable of reducing a workload for calibrating a position and a direction of each range sensor. [Solving Means] In the measurement arithmetic unit 100, the social group identification portion 5610 identifies a group candidate that is detected as a group out of moving measuring objects in each laser range finder. The group comparison portion 5612 identifies a group in agreement for each pair of the laser range finder, and calculates the relative position of each pair of the laser range finder according to the position and the directions of the identified matching group. The network position identifying portion 5620 calibrates the position and the direction of each laser range finder in the sensor network coordinate system such that the error of the position of the object observed in common from each pair becomes minimum.
