AbstractAmphibious animals adapt their body coordination to compensate for changing substrate properties as they transition between terrestrial and aquatic environments. Using behavioural experiments and mathematical modelling of the amphibious centipede Scolopendra subspinipes mutilans, we reveal an interplay between descending command (brain), local pattern generation, and sensory feedback that controls the leg and body motion during swimming and walking. The elongated and segmented centipede body exhibits a gradual transition in the locomotor patterns as the animal crosses between land and water. Changing environmental conditions elicit a mechano-sensory feedback mechanism, inducing a gait change at the local segment level. The body segments operating downstream of a severed nerve cord (no descending control) can generate walking with mechano-sensory inputs alone while swimming behaviour is not recovered. Integrating the descending control for swimming initiation with the sensory feedback control for walking in a mathematical model successfully generates the adaptive behaviour of centipede locomotion, capturing the possible mechanism for flexible motor control in animals.

As a mechanism for survival, quadrupeds have obtained skills involving coordination between limbs and the body (i.e. body–limb coordination), providing fast and adaptive locomotion compared with motion using only limbs. Several bio-inspired robotics studies have resulted in the development of legged robots that utilize a flexible spine, similar to cheetahs. However, the control principle of body–limb coordination has not been established to date. From the perspective of a decentralized control scheme, a minimal body–limb coordination mechanism is proposed in this study, in which body parts aid each other via a sensory feedback mechanism. The two-dimensional simulation and hardware experiments reveal that bilateral sensory feedback between limbs and body is essential for the robot to adaptively generate a body–limb coordination pattern and achieve faster locomotion speed than that by only limbs in efficient manner.

With the development of sensor technology and the Internet of Things (IoT) technology, the trend of miniaturization of sensors has prompted the inclusion of more sensors in IoT, and the perceptual feedback mechanism among these sensors has become particularly important, thus promoting the development of multiple sensor data fusion technologies. This paper deeply analyzes and summarizes the characteristics of sensory data and the new problems faced by the processing of sensory data under the new trend of IoT, deeply studies the acquisition, storage, and query of sensory data from the sensors of IoT in e-commerce, and proposes a ubiquitous storage method for massive sensory data by combining the sensory feedback mechanism of sensors, which makes full use of the storage resources of IoT storage network elements and maximally meets the massive. In this paper, we propose a ubiquitous storage method for massive sensing data, which makes full use of the storage resources of IoT storage network elements to maximize the storage requirements of massive sensing data and achieve load-balanced data storage. In this paper, starting from the overall development of IoT in recent years, the weak link of intelligent information processing is reinforced based on the sensory feedback mechanism of sensor technology.

The Impact

The article summarizes the current state of understanding of the concept of inner speech and evaluates the role of the internal language in the speech generation process. First, the available definitions of inner speech are presented and its features are briefly characterised. Subsequently, the inner voice is compared to overt speech and the main differences between those two planes of speech: the internal and the external one are outlined. Since the aim of the paper is to show the role of inner speech in overt speech production, a speech generation model which coalesces Levelt‘s (1993) assumptions with the stratifi cational approach to language is presented. Different stages of linguistic processing are described and the impact of internal languaging on linguistic output is discussed. It is claimed that inner speech plays a threefold role in overt speech production: (1) provides an inter-nal draft for external speech, (2) is vital for the self-monitoring system, and (3) supports working memory. Any impairment in the functioning of inner speech may thus lead to speech errors and slips of the tongue phenomena.
