Mouse brain fluorescence was imaged after the tail vein injections of indocyanine green (ICG) dye and Lexiscan. The through-skull images showed dye in the vasculatures and permeating through the blood brain barrier into the tissue.
A great need exists to non-invasively quantify the neurotransmitter activity in real-time to build a comprehensive functional map of a brain. In this paper, we present real-time recording of neuronal membrane potential change in vivo using transcranial photoacoustic (PA) voltage-sensitive dye (VSD) imaging on a rat in seizure.
Chronic schizophrenic (n = 14) and normal subjects (n = 15) were studied with magnetic resonance imaging (MRI) and positron emission tomography (PET). Two PET scans were carried out to estimate caudate dopamine D 2 receptor densities. MRI was used to measure the volume of the superior temporal gyrus. Average striatal D 2 receptor density (B max ) was significantly...
