Functional Structures From Different Components Of Intrinsic Signal In Cat Visual Cortex |
Abstract | ||
---|---|---|
Imaging of the intrinsic signal has become an important technique for visualizing sub-millimeter cortical functional structures. This activity induced signal is related to concentration changes in oxy-hemoglobin, blood volume, and changes in light scattering, as well as concentration changes in deoxy-hemoglobin. However, the relative contribution of each component to the signal is not clear. In the present study, we decomposed the signal into these different components by using a spectroscopic technique and the spatial resolution and contribution to the intrinsic signal of each component were investigated. We found that (1) blood volume changes can be spatially resolved at the columnar level, and (2) contribution of light scattering is rather high in usual conditions. |
