RIKEN SYMPOSIUM " RIKEN BSI symposium on Hippocampus "We held a symposium entitled " RIKEN BSI symposium on Hippocampus " at Okouchi Hall (RIKEN, Wako-shi) on September 14, 2009.More than a hundred foreign and domestic people gathered at the event. Thanks to all speakers and participants for their wonderfully inspiring talks, stimulating discussions and participation. |
Awards won at IJCNN 2009 in Atlanta, USAOur lab won two awards in International Joint Conference on Neural Networks (IJCNN 2009) held on June 15-19 in Atlanta.2009 INNS young investigator award was presented to Colin Molter for outstanding contribution in the field of neural networks. IJCNN 2009 runner-up student paper award presented to Utku Salihogle and Hugues Bersini from Brussel Free university, Belgium, and Yoko Yamaguchi, Colin Molter from RIKEN Brain Science Institute, Japan for the following paper : "Online organization of chaotic cell assemblies : A model for the cognitive map formation ?" |
Our paper was on a cover of NeuroReport"Dissociable neural correlates of reorienting within versus across visual hemifields"Takashi J. Ozaki, Seiji Ogawa and Tsunehiro Takeda Neuroreport 2009 Mar 25 ; 20 (5) : 497-501 / PMID : 19297739Neural correlates of reorienting of attention across visual hemifields, which was defined in early psychophysical studies (e.g. Posner, 1980), have been extensively studied. However, those of reorienting within hemifields and whether there are any differences remain unclear. In this study, the author performed a functional magnetic resonance imaging (fMRI) experiment to identify neural correlates of reorienting within and across hemifields using a variant of the cueing paradigm. The fMRI data revealed dissociable activations in the right posterior parietal region between reorienting within and across hemifields, whereas common activations appeared in the left posterior parietal region. The present results suggest that reorienting within hemifields differs from the 'classical reorienting' to some extent, whereas reorienting across hemifields does not. |

Our paper entitled :"Entorhinal Theta Phase Precession Sculpts Dentate Gyrus Place Fields" Colin Molter and Yoko Yamaguchi Hippocampus, Volume 18, Issue 9 (p 919-930)In this paper, the authors present a realistic computational model of entorhinal grid cells connected to dentate granule cells which explains the formation of hippocampal place fields. While it is agreed that place fields should be created by grid fields (e.g. McNaughton et al. 2006), the underlying mechanisms are still unknwon. In Solstad et al. (2007), it was shown that the formation of place fields necessitated selectivity in their afferents. In Rolls et al. (2007), a kind of selectivity was learned using a competitive network. However, place fields appeared to be smaller than the grid fields. Here, to produce place fields of realistic size, an important functional role is attributed to entorhinal phase precession: only grid cells firing at similar theta phase can be summed up at the connectinghippocampal cell acting as a coincident detector. The authors demonstrate that this mechanism in addition with a realistic Hebbian learning provides the necessary selectivity for the formation of place fields of realistic size.
