This is one of my all-time favorite figures. It shows the size comparison between a retinal bipolar cell and a cortical pyramidal cell in a mouse. Scale bars are great and all but sometimes the sizes just don't compute. Masland. (2012). The Neuronal Organization of the Retina. 🧪 #neuroskyence
An image showing a labelled red and green colored retina on the left hand side with a white circled bipolar cell. On the right hand side, the circled bipolar cell is shown to scale in comparison with a pyramidal neuron from the brain. It is about 1/10th the size, and barely visible.

very nice! possibly relevant, we showed making more copies of a neuron is sufficient to create tiling by homotypic repulsion (heimanlab.com/content/2016...) -- I wonder what you minimally would need to express in another cell type to get it to be treated as part of the mosaic by starburst amacrines?

Many types of retinal neurons are arranged in strikingly regular patterns known as mosaics. The term "mosaic" means that neurons of a given type are spaced evenly across the retinal surface. How do mosaics form during development? Here's a 🧵 on our new paper

Question for retina folk. We observe defects in outer retinal lamination when we directly convert a majority of mammalian Muller glia to neurons. We can rescue this, at least partially, by simultaneously inducing glial proliferation. What is the most rigorous way to quantify this?
