Dynamical adaptation in photoreceptors. [PDF]

PLoS Computational Biology, 2013
Adaptation is at the heart of sensation and nowhere is it more salient than in early visual processing. Light adaptation in photoreceptors is doubly dynamical: it depends upon the temporal structure of the input and it affects the temporal structure of ...

Switched Adaptive Sliding Mode Disturbance Observer for Nonlinear Fault-Tolerant Flight Control

IEEE Access, 2021
Typical fault scenarios such as actuator stuck, wingtip damage, and sudden center of gravity change usually bring great challenge to fault-tolerant flight control laws. In this paper, adaptive sliding mode disturbance observer (SMDO) is studied under the

Strength of baseline inter-trial correlations forecasts adaptive capacity in the vestibulo-ocular reflex. [PDF]

PLoS ONE, 2017
Individual differences in sensorimotor adaptability may permit customized training protocols for optimum learning. Here, we sought to forecast individual adaptive capabilities in the vestibulo-ocular reflex (VOR).

Capacity Analysis of Channel Inversion Using Space-Time Block Coding with Transmit Power Control

Elektronika ir Elektrotechnika, 2022
In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branch ...

The decay of motor adaptation to novel movement dynamics reveals an asymmetry in the stability of motion state-dependent learning. [PDF]

PLoS Computational Biology, 2017
Motor adaptation paradigms provide a quantitative method to study short-term modification of motor commands. Despite the growing understanding of the role motion states (e.g., velocity) play in this form of motor learning, there is little information on ...

The Potential of Shortening the Adaptation of Nellore Cattle to High-Concentrate Diets Using Only Virginiamycin as Sole Feed Additive

Frontiers in Veterinary Science, 2021
Feedlot cattle are usually adapted to high-concentrate diets containing sodium monensin (MON) in more than 14 days. However, for finishing diets with lower energy content, the use of MON during adaptation may hold dry matter intake (DMI), and ...

Sensory adaptation mediates efficient and unambiguous encoding of natural stimuli by vestibular thalamocortical pathways

Nature Communications, 2022
Sensory adaptation is widely considered to involve a trade-off between optimality and ambiguity. Here, the authors explored sensory adaptation to both naturalistic and artificial stimuli and found that, owing to contrast gain control, there is ...

Dynamics of dual prism adaptation: relating novel experimental results to a minimalistic neural model. [PDF]

PLoS ONE, 2013
In everyday life, humans interact with a dynamic environment often requiring rapid adaptation of visual perception and motor control. In particular, new visuo-motor mappings must be learned while old skills have to be kept, such that after adaptation ...

Transformation of adaptation and gain rescaling along the whisker sensory pathway.

PLoS ONE, 2013
Neurons in all sensory systems have a remarkable ability to adapt their sensitivity to the statistical structure of the sensory signals to which they are tuned.
