Progress is described regarding the development of a new electrotactile feedback glove designed for application to dexterous robot. The sensitivity of operator's finger against electrical stimulus pulse is considered. It is found that frequency, duty ratio, and voltage amplitude of electrical stimulus pulse determine the sensitivity of finger. The effects of materials, sizes, arrangements and shapes of electrodes on sensitivity of finger are analyzed. Finally, the tactile tele presence system is designed to experimentally confirm that the robot with electrotactile feedback glove can manipulate dexterous robotic multi fingered hand and identify and classify three sorts of objects. 展开更多

Vygotsky (1896-1934) pursued the objective of reformulating psychological theory. His historical-cultural analysis of the "crisis in psychology" showed that, beyond contradictions between the two main methodological currents---"objective/explanatory" and "subjective/intuitive"--psychology is primarily influenced by its empirical-sensory foundations. This influence is actually at the origin of the disagreement since it maintains the obligation for the two currents to make reference to empirical-sensory data. Only a general model of the developing human being, assessed by its usefulness, will allow reorienting psychology towards a broader science. This would lead to a general theory of psychology, which could then facilitate the search for tools for an indirect method enabling it to go beyond empiricism. 展开更多

Populations that have recently diverged offer a powerful model for studying evolution. Ecological differences are expected to generate divergent selection on multiple traits, including neurobiological ones. Animals must detect, process, and act on information from their surroundings and the form of this information can be highly dependent on the environment. We might expect different environments to generate divergent selection not only on the sensory organs, but also on the brain regions responsible for processing sensory information. Here, we test this hypothesis using recently evolved reproductively isolated species pairs of threespine stickleback fish Gasterosteus aculeatus that have well-described differences in many morphological and behavioral traits corre- lating with ecological differences. We use a state-of-the-art method, magnetic resonance imaging, to get accurate volumetric data for 2 sensory processing regions, the olfactory bulbs and optic tecta. We found a tight correlation between ecology and the size of these brain regions relative to total brain size in 2 lakes with intact species pairs. Limnetic fish, which rely heavily on vision, had relatively larger optic tecta and smaller olfactory bulbs compared with benthic fish, which utilize olfaction to a greater extent. Benthic fish also had larger total brain volumes relative to their body size compared with limnetic fish. These differences were erased in a collapsed species pair in Enos Lake where anthropogenic disturbance has led to intense hybridization. Together these data indicate that evolution of sensory processing regions can occur rapidly and independently. 展开更多

With the development of technology,the learning and memory functions of artificial memristor synapses are necessary for realizing artificial neural networks and neural neuromorphic computing.Owing to their high scalability performance,nanosheet materials have been widely employed in cellular-level learning,but the behaviors of nociceptor based on nanosheet materials have rarely been studied.Here,we present a memristor with an Al/TiO_(2)/Pt structure.After electroforming,the memristor device showed a gradual conductance regulation and could simulate synaptic functions such as the potentiation and depression of synaptic weights.We also designed a new scheme that verifies the pain sensitization,desensitization,allodynia,and hyperalgesia behaviors of real nociceptors in the fabricated memristor.Memristors with these behaviors can significantly improve the quality of intelligent electronic devices.Data fitting showed that the high resistance and low resistance states were consistent with the hopping conduction mechanism.This work promises the application of TiO_(2)-based devices in next-generation neuromorphological systems. 展开更多
