| Research Abstract |
We have studied the central motor control mechanism using non-invasive procedures in human, such as positron emission tomography (PET), functional magnetic resonance imaging, magnetoencephalography, evoked potentials. To expand these research activities, we adopted the animal experiments, especially combined with PET and other electrophysiological examinations, based on our experience in collaborative study on animal PET among Kyoto University, Fukui Medical School and Hamamatsu photonics. On these backgrounds, we planned to build a new animal PET machine suitable for small animals, such as cat, rat and mouse, in order to study detailed mechanisms concerning the motor and sensory integration in normal and pathological movements. (1) We developed a new PET machine for animal use, with the spacial resolution, 3.5 x 3.5 x 4.5 mm in half width full maximum. The gantry was fixed so that we could have a large space around the scanner. (2) We verified the valid calculation method for glucose metabolic rate (CMRglc) in small animal with PET.As the large Harderian gland is located in front of and beneath the frontal lobe in rat or mouse, we measured the CMRglc in normal and Harderian glands resected rats, and found no remarkable effect of Harderian glands on CMRglc. (3) We exemplified the cholinergic and glutamatergic neurons to participate in the regulation of cerebral cortical neurons using animal PET.
