CORNET - Die Integration von top-down und bottom-up Einflüssen im Cortex von Marmosets und Makaken
Zusammenfassung der Projektergebnisse
In experiments in anesthetized marmosets, hdECoG grids provided high-quality RFs from 240 sites over early and simultaneously 240 sites over higher visual areas. The additionally inserted laminar microelectrodes could record neuronal activity throughout the cortex. Optogenetic activation of neurons within and across areas was achieved in two animals, as confirmed with data analysis and histology. In experiments in awake marmosets, laminar probes recorded from a total of 192 channels in V1 and V4, combined with optogenetic control in V6. The latter had behavioral effects. DCM was able to provide excellent fits to the electrophysiological data and the effects of attention. The completed mouse connectivity study has proved to be surprising and we have been able to show that the published data in high profile Journals is incorrect. This makes the publication of this work very sensitive. This has forced us to move this project to a high priority and to complete the work much earlier than planned, and to complete these Deliverables more than 2-years earlier than planned. This work was presented at an international meeting on rodent neurobiology held in Suzhou, (China) in November 2016, where the major groups involved in developing rodent connectomes present their work. This work is now published in Neuron. Our overlapping interests in cortical processing and the high quality data that each lab has established opens the way to further collaborations that has been explored and developed in the Core-Net program. One particularly exciting possibility is the further development of the functional data from ESI using graph theoretic techniques that we have been applying to the structural data at SBRI.
