High resolution fMRI

Neuronal Architecture in the Rat

These data were acquired using a 11.7T BioSpec.
 

(A; top left) BOLD-fMRI correlation coefficient map of forepaw stimulation
 
(B, top right) Corresponding time course of forepaw stimulation. Heterogeneity corresponds to individual cortical layers (50 µ resolution).
 
(C, D; bottom) T1W-MRI is possible at this field strength after Mn2+ administration (cortical layers in olfactory bulb and somatosensory cortex; 100 µ resolution).
