Conditional protein tagging methods reveal highly specific subcellular distribution of ion channels in motion-sensing neurons

eLife, 2020
Neurotransmitter receptors and ion channels shape the biophysical properties of neurons, from the sign of the response mediated by neurotransmitter receptors to the dynamics shaped by voltage-gated ion channels.

Environment Perception with Chameleon-Inspired Active Vision Based on Shifty Behavior for WMRs

Applied Sciences, 2023
To improve the environment perception ability of wheeled mobile robots (WMRs), the visual behavior mechanism of the negative-correlation motion of chameleons is introduced into the binocular vision system of WMRs, and a shifty-behavior-based environment ...

Limb, joint and pelvic kinematic control in the quail coping with steps upwards and downwards

Scientific Reports, 2022
Small cursorial birds display remarkable walking skills and can negotiate complex and unstructured terrains with ease. The neuromechanical control strategies necessary to adapt to these challenging terrains are still not well understood.

Design and Test of a Spatial Nanopositioner for Evaluating the Out-of-Focus-Plane Performance of Micro-Vision

Micromachines, 2023
Micro-vision possesses high in-focus-plane motion tracking accuracy. Unfortunately, out-of-focus-plane displacements cannot be avoided, decreasing the in-focus-plane tracking accuracy of micro-vision.

Closed-loop response properties of a visual interneuron involved in fly optomotor control

Frontiers in Neural Circuits, 2013
Due to methodological limitations neural function is mostly studied under open-loop conditions. Normally, however, nervous systems operate in closed-loop where sensory input is processed to generate behavioural outputs, which again change the sensory ...

Different spectral sensitivities of ON- and OFF-motion pathways enhance the detection of approaching color objects in Drosophila

Nature Communications, 2023
Color and motion are used by many species to identify salient objects. They are processed largely independently, but color contributes to motion processing in humans, for example, enabling moving colored objects to be detected when their luminance ...

Motion deblurring in human vision [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1997
Under normal viewing conditions we are little conscious of blur in moving objects, despite the persistence of vision. Moving objects look more blurred in brief than in long exposures, suggesting an active mechanism for suppressing motion blur.

A common directional tuning mechanism of Drosophila motion-sensing neurons in the ON and in the OFF pathway

eLife, 2017
In the fruit fly optic lobe, T4 and T5 cells represent the first direction-selective neurons, with T4 cells responding selectively to moving brightness increments (ON) and T5 cells to brightness decrements (OFF).

Vision-based speedometer regulates human walking

iScience, 2021
Summary: Can we recover self-motion from vision? This basic issue remains unsolved since, while the human visual system is known to estimate the direction of self-motion from optic flow, it remains unclear whether it also estimates the speed. Importantly,

Vision Statement: Materials in Motion [PDF]

Advanced Materials, 2020
AbstractAt the dawn of a new era of interactive and responsive materials and dynamic molecular systems there is ample opportunity to raise the level of complexity enabling mechanical motion, autonomous behavior, or interactive self‐regulatory functions.
