What’s all the Fos about? (staining protocol)

Many studies on memory and learning utilize the immediate early gene c-Fos as an indicator of recent synaptic activity. By quantifying c-Fos positive neurons, we can compare activity across different populations in the brain, and analyze co-labelled neurons with other useful cell markers such as BrdU and Doublecortin. Our lab…

Tracing Neurons using FIJI (ImageJ)

CONFOCAL IMAGING The image files used in this tutorial were taken using a Leica confocal microscope (model SP8). Using fluorescent imaging technique (*) and an extra spatial filter, this confocal can selectively collect light at a specific z-plane, filtering out any out-of-focus illumination. A series of clear 2D images can…

Olfactory bulb neurogenesis big bigger biggest

And now for a journey outside (rostral, to be precise) of my comfort zone. These three pictures show new neurons in the mouse olfactory bulb at successively greater magnifications. Probably inspired by the science magazine I read as a kid that would show high mag photos of everyday objects (with corresponding…
