Article Title: Investigation of the BOLD and CBV fMRI responses to somatosensory stimulation in awake marmosets ( Callithrix jacchus )
doi: 10.1002/nbm.3864
Figure Lengend Snippet: (A) BOLD (top) and CBV t-score functional maps obtained at two different doses of MION (middle: 20 mg/kg; bottom: 30 mg/kg) in response to a 4 s stimulus duration. Robust BOLD and CBV activations were observed in S1, S2 and caudate. However, caudate showed no CBV activation at either dosage of MION. (B) Mean BOLD HRF (top graph) and mean CBV HRFs obtained with the lower dose (middle graph) and the higher dose of USPIO (bottom graph), in response to a 4 s stimulus, averaged across all five subjects. A stronger CBV response was observed at the higher dose of 30 mg/kg. Error bars = 1 std. dev. *P < 0.05.
Article Snippet: An initial dose of 20 mg/kg of 30 nm (USPIO) particles (Molday ION, Biophysics Assay Laboratory, Inc., Worcester, MA) was injected to the animals intravenously.
