A dendrite-resolved, in vivo transfer function from spike patterns to dendritic Ca2+

Xiang Wu, Byung Hun Lee, Pojeong Park, J. David Wong-Campos, Junjie Xu, Sarah E. Plutkis, Luke D. Lavis, Adam E. Cohen

This study measures the voltage-to-Ca2+ transfer function in hippocampal CA2 pyramidal neurons during behavior and develops a biophysics-inspired model to predict Ca2+ signals from voltage waveforms.

Dendritic excitations primarily mediate back-propagation in CA1 pyramidal neurons during behavior

Byung Hun Lee, Pojeong Park, Xiang Wu, J. David Wong-Campos, Junjie Xu, Marley Xiong, Yitong Qi, Yi-Chieh Huang, Daniel G. Itkis, Sarah E. Plutkis, Luke D. Lavis, Adam E. Cohen

This study maps dendritic membrane potential dynamics in CA1 neurons during behavior, showing dendritic spikes are driven by back-propagating action potentials and influence spiking outputs and plasticity.

Data-mining of Antibiotic Resistance Genes Provides Insight into the Community Structure of Ocean Microbiome

Shiguang Hao, Pengshuo Yang, Maozhen Han, Junjie Xu, Shaojun Yu, Chaoyun Chen, Wei-Hua Chen, Houjin Zhang, Kang Ning

The paper analyzes marine antibiotic resistance genes (ARGs) and their associations with bacterial communities using Tara Oceans metagenomic data, finding higher ARG abundance and diversity in mesopelagic zones and ARG-enriched genera being more abundant than their ARG-less counterparts.
