abstractAn intracerebral information measuring device which can be mounted to the head of a subject by a simple surgery and which attains measurement of low invasion, high sensitivity, and high resolution. An internally mounted unit (1A) is composed of a probe section (2A) to be set to enter the brain through a hole having a small diameter pierced in the skull (102) of the subject, and a head section (3A) integrated with the probe section (2A) and to be disposed between the skull (102) and the scalp (101). The probe section (2A) comprises an electrode for picking-up action potential etc., and the head section (3A) comprises a delivery section wirelessly delivering a signal obtained thereby to outside. In the exterior of the head (100), an external measuring unit (10A) is installed, which receives the signal delivered from the head section (3A) and reproduces thereof. A burden or risk onto the subject is small since a large-scale craniotomy procedure is not required in order to mount the internally mounted unit (1A), and sensitivity and resolution can be improved since the signal can be taken out directly from the inside of the brain.
