In this belated, crazy, #EM_Monday I am posting an image I took showing some organellar communications at a neuronal soma: a mitochondria contacting nuclear envelope, and Golgi going all the way from nuclear envelope to plasma membrane.

This #EM_Monday is a neuron (magenta) dumping its lysosome (blue arrow) into a glia- I think!

This #EM_Monday highlights how organelles can shape cells in 🧠! E.g. glia, with their thin processes, often wrap around neurons. But when organelles like lipid droplets (LDs) are present, they can create dents in neighboring neurons—like the one shown here, where a glial LD indents neurons' somas🧵

This #EM_Monday, is the follow-up of something I posted before on the other place. I posted about these axon curling their way into other pre-synapse, forming funny spinules. This was from mouse visual cortex (www.microns-explorer.org), and not super common.

Our paper is out just in time for #EM_Monday! It is about a specialized neuron-specific ER, called the spine apparatus, which is found close to synapses and has a very peculiar shape. If you think neurons are special, the spine apparatus is their🦄 horn! But how does it form?!

I will show an inverted pyramidal (pink) neuron from mouse visual cortex. You can see for comparison in blue a typical pyramidal neuron in blue, with its primary dendrite pointing toward L1, and its axon going 👇. In contrast our inverted friend looks exactly the same, just flipped!

I’m excited to kick off a new series of #EM_Monday! Let’s start with mitochondria that act like magnets, aligning their cristae when they contact each other. This fascinating phenomenon has been reported before, such as in muscle tissue. doi.org/10.1038/ncom...
