Contact-Dependent Ion Gating Explains Directional Asymmetry in the Bacterial Flagellar Motor
Jiading Zhu, Yongnan Hu, Yuhai Tu +1
The bacterial flagellar motor (BFM) is a rotary molecular machine driven by the ion electrochemical potential across the cell membrane. Recent cryo-EM structures reveal a cogwheel-…

Ultrasensitivity without conformational spread: A mechanical origin for non-equilibrium cooperativity in the bacterial flagellar motor
Henry H. Mattingly, Yuhai Tu
Flagellar motors enable bacteria to navigate their environments by switching rotation direction in response to external cues with high sensitivity. Previous work suggested that ult…

Representational Drift and Learning-Induced Stabilization in the Olfactory Cortex
Guillermo B. Morales, Miguel A. Muñoz, Yuhai Tu
The brain encodes external stimuli through patterns of neural activity, forming internal representations of the world. Recent experiments show that neural representations for a giv…
