Enhancement of Spike-Timing-Dependent Plasticity in Spiking Neural Systems with Noise.

International journal of neural systems
Synaptic plasticity is widely recognized to support adaptable information processing in the brain. Spike-timing-dependent plasticity, one subtype of plasticity, can lead to synchronous spike propagation with temporal spiking coding information. Recen...

A GPU-accelerated cortical neural network model for visually guided robot navigation.

Neural networks : the official journal of the International Neural Network Society
Humans and other terrestrial animals use vision to traverse novel cluttered environments with apparent ease. On one hand, although much is known about the behavioral dynamics of steering in humans, it remains unclear how relevant perceptual variables...

Firing rate dynamics in recurrent spiking neural networks with intrinsic and network heterogeneity.

Journal of computational neuroscience
Heterogeneity of neural attributes has recently gained a lot of attention and is increasing recognized as a crucial feature in neural processing. Despite its importance, this physiological feature has traditionally been neglected in theoretical studi...

The effect of aspect ratio on the leading-edge vortex over an insect-like flapping wing.

Bioinspiration & biomimetics
Insect wing shapes are diverse and a renowned source of inspiration for the new generation of autonomous flapping vehicles, yet the aerodynamic consequences of varying geometry is not well understood. One of the most defining and aerodynamically sign...

Principles of appendage design in robots and animals determining terradynamic performance on flowable ground.

Bioinspiration & biomimetics
Natural substrates like sand, soil, leaf litter and snow vary widely in penetration resistance. To search for principles of appendage design in robots and animals that permit high performance on such flowable ground, we developed a ground control tec...

Effects of non-uniform stiffness on the swimming performance of a passively-flexing, fish-like foil model.

Bioinspiration & biomimetics
Simple mechanical models emulating fish have been used recently to enable targeted study of individual factors contributing to swimming locomotion without the confounding complexity of the whole fish body. Yet, unlike these uniform models, the fish b...

Imparting protean behavior to mobile robots accomplishing patrolling tasks in the presence of adversaries.

Bioinspiration & biomimetics
Providing unpredictable trajectories for patrol robots is essential when coping with adversaries. In order to solve this problem we developed an effective approach based on the known protean behavior of individual prey animals-random zig-zag movement...

Effect of earthworm active protein on fibroblast proliferation and its mechanism.

Pharmaceutical biology
CONTEXT: Earthworms have been used as a traditional medicine in China from thousands of years. In recent years, research has demonstrated that earthworm extracts might promote wound healing; however, its mechanism is still unknown.

Survey of Natural Language Processing Techniques in Bioinformatics.

Computational and mathematical methods in medicine
Informatics methods, such as text mining and natural language processing, are always involved in bioinformatics research. In this study, we discuss text mining and natural language processing methods in bioinformatics from two perspectives. First, we...

Real-Time Simulation of Passage-of-Time Encoding in Cerebellum Using a Scalable FPGA-Based System.

IEEE transactions on biomedical circuits and systems
The cerebellum plays a critical role for sensorimotor control and learning. However, dysmetria or delays in movements' onsets consequent to damages in cerebellum cannot be cured completely at the moment. Neuroprosthesis is an emerging technology that...
