Abstract:
The combination of functional and spectroscopic MRI with invasive measurements of neural activity in monkeys may help us investigate levels of neural organization revealing both how networks are organized and how small assemblies contribute to this organization. Insights can be gained into long-range neural interactions, learning-related neurochemical changes, dynamic connectivity by means of MR labeling techniques, and plasticity and reorganization following lesions. Insights are also gained into the relationship between the fMRI signal and the underlying neuronal activity that we think it represents. In my talk I’ll describe such applications and discuss their contribution in our understanding of neural mass activity.
