我们开发了一种光声模式,用于直接成像Fos-LacZ转基因大鼠中表达Fos的神经元群。X-Gal产物为神经元团的成像提供了外源性对比。我们检测到在给予可卡因或休克音调配对范例后,Fos表达激活的神经元群。测量复杂行为背后的神经活动有助于理解支持这些行为的微电路。我们开发了一种功能和分子光声断层成像(F/M-PAT)系统,该系统可以大视场和高空间分辨率直接成像Fos-LacZ转基因大鼠表达Fos的神经元群。F/M-PAT测定外源性发色团X-Gal在整体神经元中的β-半乳糖苷酶催化产物。我们在Wistar Fos-LacZ转基因大鼠中使用了一种体外成像方法,检测了在给予可卡因或冲击音对刺激后,内侧前额叶皮质(MPFC)的神经元群。在两种情况下(与单纯对照相比),mPFC神经元中都检测到了稳健和选择性的F/M-PAT信号,这表明使用这种方法可以成功和直接地检测到表达Fos的神经元团。这项研究的结果表明,F/M-PAT可以与Fos-Lacz大鼠结合使用,以监测作为一系列行为过程(如恐惧学习或成瘾)的基础的神经元集合。
We developed a photoacoustic modality for direct imaging of Fos-expressing neuronal ensembles in Fos-LacZ transgenic rats. X-gal product provided exogenous contrast for imaging of neuronal ensembles. We detected Fos-expressing activated neuronal ensembles after either cocaine administration or a shock-tone pairing paradigm. Measuring neuroactivity underlying complex behaviors facilitates understanding the microcircuitry that supports these behaviors. We have developed a functional and molecular photoacoustic tomography (F/M-PAT) system which allows direct imaging of Fos-expressing neuronal ensembles in Fos-LacZ transgenic rats with a large field-of-view and high spatial resolution. F/M-PAT measures the beta-galactosidase catalyzed enzymatic product of exogenous chromophore X-gal within ensemble neurons. We used an ex vivo imaging method in the Wistar Fos-LacZ transgenic rat, to detect neuronal ensembles in medial prefrontal cortex (mPFC) following cocaine administration or a shock-tone paired stimulus. Robust and selective F/M-PAT signal was detected in mPFC neurons after both conditions (compare to naive controls) demonstrating successful and direct detection of Fos-expressing neuronal ensembles using this approach. The results of this study indicate that F/M-PAT can be used in conjunction with Fos-LacZ rats to monitor neuronal ensembles that underlie a range of behavioral processes, such as fear learning or addiction.
