Primate layer III pyramidal neurons in dorsolateral prefrontal cortex express high levels of calcium-related genes such as CACNA1C and CALB1. Why? In this collaboration with Amy Arnsten and Dibs Datta, we combined snRNA-seq with immuno-EM, physiology and pharmacology to localize key channels on layer III dendritic spines and that both low and high L-type calcium channel activity negatively modulates delay cell firing.

Fenna receives a 2023 Klingenstein-Simons Fellowship! 

 

07-06-23

 

The Klingenstein-Simons Fellowship Awards in Neuroscience supports early career investigators engaged in basic or clinical research that may lead to a better understanding of neurological and psychiatric disorders. The fellowship awards promote high-risk, and potentially high-reward, projects. Aimed at advancing cutting-edge investigations, the awards are presented to highly promising, early career scientists. The Krienen lab's project will focus on reconstructing the developmental basis of cellular innovations in primate brains.

Krienen lab (PNI) & Mallarino lab (Mol) jointly awarded an Eric & Wendy Transformative Technologies Fund

KRIENEN LAB JOINS THE BICAN!

10-22

We're thrilled to be part of a new a global collaboration with the Allen Institute to develop comprehensive, single cell atlases of the human and nonhuman primate brain. The collaboration is funded by the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative as part of The BRAIN Initiative® Cell Atlas Network, or BICAN, and includes projects led by researchers from 17 other institutions across the US, Europe and Japan.

 

The Krienen lab will lead efforts to comprehensively map the molecular repertoire of cell types in the marmoset brain, and conduct comparative analysis of homologous cell types in other species including humans. A key aim is to elucidate how brain cell types evolve in mammalian lineages. Understanding the conservation and divergence of cell types across species enables better translation between what we see in animal studies and animal models with the structure and function of the human brain itself.
