Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Assessment of stereoscopic optic disc images using an autostereoscopic screen - experimental study [PDF]

, 2008
BACKGROUND: Stereoscopic assessment of the optic disc morphology is an important part of the care of patients with glaucoma. The aim of this study was to assess stereoviewing of stereoscopic optic disc images using an example of the new technology of ...

The role of optic flow on reactive brain processing in cognitive tasks during locomotion

Brain Research Bulletin
Perception and action share neural resources that must be flexibly allocated across simultaneous tasks. In this context, the optic flow provides key visual input during locomotion and may interact with concurrent cognitive processing. This study aimed to:

A Bio-inspired Collision Avoidance Model Based on Spatial Information Derived from Motion Detectors Leads to Common Routes. [PDF]

PLoS Computational Biology, 2015
Avoiding collisions is one of the most basic needs of any mobile agent, both biological and technical, when searching around or aiming toward a goal.

Heading perception depends on time-varying evolution of optic flow

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Instantaneous optic flow, image velocity across the visual field, contains information about self-motion (heading). Indeed, computer vision algorithms estimate heading from instantaneous optic flow accurately despite co-occurring rotation ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Function of a Fly Motion-Sensitive Neuron Matches Eye Movements during Free Flight [PDF]

, 2005
Sensing is often implicitly assumed to be the passive acquisition of information. However, part of the sensory information is generated actively when animals move.

Integration of parallel pathways for flight control in a hawkmoth reflects prevalence and relevance of natural visual cues

eLife
An animal’s behaviour is the result of multiple neural pathways acting in parallel, receiving information across and within sensory modalities at the same time. How these pathways are integrated, particularly when their individual outputs are in conflict,

Using Optic Flow for the Estimation of Travel Distance

i-Perception, 2011
Much research on optic flow has been concerned with the estimation of heading and the control of the direction of self-motion. In my presentation I will instead focus on a different use of optic flow, namely the estimation of the distance that one has ...

The Shape of a Vehicle Windshield Affects Reaction Time and Brain Activity During a Target Detection Task

Frontiers in Human Neuroscience, 2020
Background: Achieving clear visibility through a windshield is one of the crucial factors in manufacturing a safe and comfortable vehicle. The optic flow (OF) through the windshield has been reported to divert attention and could impair visibility ...
