Kinds of Maps

By Nathan Eisenberg Mapping is the phenomenon where the spatial arrangement or molecular distribution of neuronal networks reflects the functional interactions of said network. One type of mapping is that of topographic mapping, in which the spatial or otherwise systematic character of the neurons’ up- and down-stream targets is borne out in the physical proximities […]

Urban Planning in the Eye

The retina may seem like a unified, homogenous structure, but really it’s more like a city, with different building types and an organized layout. We would scoff at a city with two libraries next to each other, or a tiny cottage sandwiched between skyscrapers. The retina avoids its own versions of these problems by creating […]

Rod vs. Cone Regeneration in the Teleost Retina

By Ingrid Tower It’s 4am and you’ve gotta pee. You sit up on your bed and and search for the outlet to insert your lamp plug, because you still haven’t fixed the on/off switch. Can’t find it. Great. You must now fumble through the dark to find your way to your oh-so-far-off door.  Relax. Take […]

A Tale of Two Mutants

By Emily Crotteau What if your eyes could regenerate over time, saving you from the declining vision many people face as they age? Scientists are hoping to find answers to this question by studying
fish, whose eyes possess regenerative capacity throughout their lives. Fish and humans are distantly related, but if fish evolved their eye-regenerating abilities […]

Eat to grow…

By Karen Dewey Everyone must eat to live; we all know this from day one. We get all our energy from food, but what else does a good diet do for us? Our bodies store energy in fat deposits that have effects on a cellular level, effects so small that we never really notice them. […]

Awakenings: Stem Cell Style

Jack Craig In the semitropical South-East of the United States there’s a plant called the miracle fern (Pleopeltis polypodioides). In adverse conditions, it’s capable of curling up, drying out and remaining dormant for years on end, only to spring back to life when the weather improves. It can do this any number of times, entering […]

Decisions, Decisions

Blimp1 Controlled Cell Fate Decisions in Mouse Retinal Development By Miranda Lyons-Cohen Photoreceptors are the cells in the retina that detect light. Photoreceptors are in the outer most layer of the 3-layered retina. Bipolar cells (BCs) are “interneurons” that are located between the retinal ganglion cell (RGC) layer and the photoreceptors, relaying information between the […]
