2021 NeuroImage  
To achieve these goals within the non-human primate (NHP) imaging community, there is a pressing need for the use of standardized and validated localizers that can be readily implemented across different  ...  As has been shown with the aggregation of resting-state imaging data in the original PRIME-DE submissions, we believe that the field is ready to apply the same initiative for task-based functional localizers  ...  Importance of functional localizers in the study of primate brain functions Localizers are extensively used in fMRI studies, whether in human or non-human primates, in order to identify cortical regions  ...

Local Field Potentials, BOLD, and Spiking Activity: Relationships and Physiological Mechanisms [chapter]

2011 Visual Population Codes  
In this chapter, we examine recent advances and results regarding the origin, the feature selectivity and the spatial resolution of the local field potential and discuss its relationship to local spiking  ...  We conclude that in contrast to spikes, the local field potential does not measure the output of the computation performed by a cortical circuit, but are rather indicative of the synaptic and dendritic  ...  (B) In primary visual cortex of awake primates, oscillations in the gamma-band of the LFP are dominant during visual stimulation, as illustrated in the example.  ...
