Excited to share our new paper on the evolution of inhibitory neurons in the retina 👀 now out in Science Advances! www.science.org/doi/10.1126/... Please see my previous post for a brief summary: bsky.app/profile/dari...

The extreme diversity of retinal amacrine cells has deep evolutionary roots

Amacrine cells (ACs) comprise a heterogeneous class of inhibitory neurons in the vertebrate retina, exhibiting morphological and functional complexity rivaling that of cortical interneurons. Here, we ...

New preprint! A wonderful collaboration of our @FellerMarla lab with Matthew Po, and @shekharlab. Here, we dive into the impact of spontaneous activity on the transcriptome of retinal ganglion cells (RGCs), the sole output neurons of the retina. www.biorxiv.org/content/10.1...

Transcriptomic changes in retinal ganglion cell types associated with the disruption of cholinergic retinal waves

In the early stages of retinal development, a form of correlated activity known as retinal waves causes periodic depolarizations of immature retinal ganglion cells (RGCs). Retinal waves are crucial fo...

As my first post here, I am really excited to share a new manuscript with @ralitsamadsen.bsky.social on this platform. We looked how non-equilibrium thermodynamics helps ligand discrimination in signaling networks: t.co/ZA6NteUmaS
