It has not been addressed whether 2A peptide-mediated coexpression of heterologous proteins is quantitative in neurons and expression levels of fluorescent reporters would be high enough for in vi ...

What insights can fMRI offer into the structure and function of mid-tier visual areas?
... our resolution is in the 2–5 mm range (Olman & Yacoub, 2011). The danger of the term “neural activity” is that it can be used to imply homogeneity in a heterogeneous and inadequately sampled neural population. Neuron density is on the order of 10,000 neurons/mm3 throughout cortex, as high as 40,000 ...
