Outline of Final Research Achievements

Advances in PET imaging technologies with high sensitivity and resolution have enabled us to study dynamic changes of neurotransmitters and neural activity in small animals. Along the line, we focused on the reward system which is one of the fundamental brain function of living bodies and employed the paradigm of “intracranial self-stimulation (ICSS)” to elucidate the reward neural network by using small animal neuroimaging technique. As a result of our attempt, we found that ICSS has activated the lateral periaqueductal gray and vestibular nuclei, lateral posterior nuclei of thalamus but suppressed the neural activity in the nucleus accumbens or subiculum, insular cortex.
