Research Abstract |
The project evaluated the following : 1) The lateral intraparietal area receives projections from the area V3A and projects to the anterior intraparietal area. 2) The connectional details of the V3A. 3) The connections of VP with V3A and V2. The lateral intraparietal area (LIP) of Japanese monkey is located in the lateral bank of the intraparietal sulcus and plays a role in recognition of the space and construction of motor space. In this study, responses of neurons in the posterior part of the LIP to the 3D computer graphic images were recorded electrophysiologically. We also showed that the LIP receives projections from V3A and projects to the anterior intraparietal area. The latter area reported to projects to the premotor areas, and thus the connections of LIP may play a role in motor space construction. The results were published in the Journal of Neuroscience, one of the most highly rated international journals.
