Fold Change Detection in Visual Processing

Frontiers in Neural Circuits, 2021
Visual processing transforms the complexities of the visual world into useful information. Ciona, an invertebrate chordate and close relative of the vertebrates, has one of the simplest nervous systems known, yet has a range of visuomotor behaviors. This

Bio-Inspired Visuomotor Convergence in Navigation and Flight Control Systems [PDF]

, 2005
Insects exhibit incredibly robust closed loop flight dynamics in the face of uncertainties. A fundamental principle contributing to this unparalleled behavior is rapid processing and convergence of visual sensory information to flight motor commands via ...

Cerebello-Cortical Differences in Effective Connectivity of the Dominant and Non-dominant Hand during a Visuomotor Paradigm of Grip Force Control

Frontiers in Human Neuroscience, 2017
Structural and functional differences are known to exist within the cortical sensorimotor networks with respect to the dominant vs. non-dominant hand.

Visuomotor behaviours when using a myoelectric prosthesis [PDF]

, 2014
Background: A recent study showed that the gaze patterns of amputee users of myoelectric prostheses differ markedly from those seen in anatomically intact subjects.

Parallel visual circuitry in a basal chordate

eLife, 2019
A common CNS architecture is observed in all chordates, from vertebrates to basal chordates like the ascidian Ciona. Ciona stands apart among chordates in having a complete larval connectome.

Intermittent Visual Occlusions Increase Balance Training Effectiveness

Frontiers in Human Neuroscience, 2022
Improving dynamic balance can prevent falls in humans with neurological and mechanical deficits. Dynamic balance requires the neural integration of multisensory information to constantly assess the state of body mechanics.

A Primitive Memory System for Attention Deployments: Some Recent Challenges and Their Resolution

i-Perception, 2011
In the past my colleagues and I have presented evidence for the existence of a primitive memory for attention deployments. This memory system orients attention to features and locations of recent behavioral importance.

Recurrent network interactions explain tectal response variability and experience-dependent behavior

eLife, 2023
Response variability is an essential and universal feature of sensory processing and behavior. It arises from fluctuations in the internal state of the brain, which modulate how sensory information is represented and transformed to guide behavioral ...

NMDA receptors in visual cortex are necessary for normal visuomotor integration and skill learning

eLife, 2022
The experience of coupling between motor output and visual feedback is necessary for the development of visuomotor skills and shapes visuomotor integration in visual cortex.

Improving Precision Force Control With Low-Frequency Error Amplification Feedback: Behavioral and Neurophysiological Mechanisms

Frontiers in Physiology, 2019
Although error amplification (EA) feedback has been shown to improve performance on visuomotor tasks, the challenge of EA is that it concurrently magnifies task-irrelevant information that may impair visuomotor control.
