An engineered biosensor enables dynamic aspartate measurements in living cells

Kavli Affiliate: Timothy Brown | Authors: Kristian Davidsen, Jonathan S Marvin, Abhi Aggarwal, Timothy A Brown and Lucas B Sullivan | Summary: Intracellular levels of the amino acid aspartate are responsive to changes in metabolism in mammalian cells and can correspondingly alter cell function, highlighting the need for robust tools to measure aspartate abundance. However, […]

Brain-wide measurement of protein turnover with high spatial and temporal resolution

Kavli Affiliate: Timothy Brown | Authors: Boaz Mohar, Jonathan B. Grimm, Ronak Patel, Timothy A. Brown, Paul Tillberg, Luke D. Lavis, Nelson Spruston and Karel Svoboda | Summary: Cellular functions are regulated by synthesizing and degrading proteins on time scales ranging from minutes to weeks. Protein turnover varies across proteins, cellular compartments, cell types, and […]

Random noise promotes slow heterogeneous synaptic dynamics important for robust working memory computation

Kavli Affiliate: Terrence Sejnowski | Authors: Nuttida Rungratsameetaweemana, Robert Kim, Thiparat Chotibut and Terrence Sejnowski | Summary: Recurrent neural networks (RNNs) based on model neurons that communicate via continuous signals have been widely used to study how cortical neurons perform cognitive tasks. Training such networks to perform tasks that require information maintenance over a brief […]

Cross-Modal Representation of Identity in Primate Hippocampus

Kavli Affiliate: Cory Miller | Authors: Timothy Tyree, Michael Metke and Cory Miller | Summary: Faces and voices are the dominant social signals used to recognize individuals amongst human and nonhuman primates (1–4). Yet it is not known how these critical signals are integrated into a cross-modal representation of individual identity in the primate brain. […]

Glaucoma-associated Optineurin mutations increase transmitophagy in a vertebrate optic nerve

Kavli Affiliate: Mark Ellisman | Authors: Yaeram Jeong, chung-ha Davis, Aaron Muscarella, Viraj Deshpande, Keun-Young Kim, Mark Ellisman and Nicholas Marsh-Armstrong | Summary: We previously described a process referred to as transmitophagy where mitochondria shed by retinal ganglion cell (RGC) axons are transferred to and degraded by surrounding astrocytes in the optic nerve head of […]

High-resolution volumetric imaging constrains compartmental models to explore synaptic integration and temporal processing by cochlear nucleus globular bushy cells

Kavli Affiliate: Mark Ellisman | Authors: George A. Spirou, Matthew Kersting, Sean Carr, Bayan Razzaq, Carolyna Y. Alves-Pinto, Mariah Dawson, Mark H. Ellisman and Paul B. Manis | Summary: Globular bushy cells (GBCs) of the cochlear nucleus play central roles in the temporal processing of sound. Despite investigation over many decades, fundamental questions remain about […]

Domain-specific cognitive impairment reflects prefrontal dysfunction in aged common marmosets

Kavli Affiliate: John Reynolds | Authors: Courtney Glavis-Bloom, Casey R Vanderlip, Payton A Asch and John H Reynolds | Summary: Age-related cognitive impairment is not expressed uniformly across cognitive domains. Cognitive functions that rely on brain areas that undergo substantial neuroanatomical changes with age often show age-related impairment, while those that rely on brain areas […]

Dopamine signaling regulates predator-driven changes in Caenorhabditis elegans egg laying behavior

Kavli Affiliate: Sreekanth Chalasani | Authors: Amy Pribadi, Michael A Rieger, Kaila Rosales, Kirthi C Reddy and Sreekanth H Chalasani | Summary: Prey respond to predators by altering their behavior to optimize their own fitness and survival. Specifically, prey are known to avoid predator-occupied territories to reduce their risk of harm or injury to themselves […]
