Bio-inspired Model of Spatial Cognition
"... Abstract. We present the results of an ongoing research in the area of symbol grounding. We develop a biologically inspired model for grounding the spatial terms that employs separate visual what and where subsystems that are integrated with the symbolic linguistic subsystem in the simplified neura ..."

The faculty of language: what is it, who has it, and how did it evolve?
- Science,
, 2002
"... We argue that an understanding of the faculty of language requires substantial interdisciplinary cooperation. We suggest how current developments in linguistics can be profitably wedded to work in evolutionary biology, anthropology, psychology, and neuroscience. We submit that a distinction should ..."

be made between the faculty of language in the broad sense (FLB) and in the narrow sense (FLN). FLB includes a sensory-motor system, a conceptual-intentional system, and the computational mechanisms for recursion, providing the capacity to generate an infinite range of expressions from a finite set
Computational Models of Sensorimotor Integration
- SCIENCE
, 1997
"... The sensorimotor integration system can be viewed as an observer attempting to estimate its own state and the state of the environment by integrating multiple sources of information. We describe a computational framework capturing this notion, and some specific models of integration and adaptati ..."

Psychophysical results from two sensorimotor systems, subserving the integration and adaptation of visuo-auditory maps, and estimation of the state of the hand during arm movements, are presented and analyzed within this framework. These results suggest that: (1) Spatial
BIO-INSPIRED DYNAMIC FORMANT TRACKING FOR PHONETIC LABELLING
"... It is a known fact that phonetic labeling may be relevant in helping current Automatic Speech Recognition (ASR) when combined with classical parsing systems as HMM's by reducing the search space. Through the present paper a method for Phonetic Broad-Class Labeling (PCL) based on speech percepti ..."

Examples of phonetic class labeling are given and the applicability of the method to Speech Processing is discussed. discussing the fundamentals of speech understanding, helping to devise a general bio-inspired architecture for Cognitive Audio in the long range. For such a
The motor theory of speech perception revised
- Cognition
, 1985
"... A motor theory of speech perception, initially proposed to account for results of early experiments with synthetic speech, is now extensively revised to accommodate recent findings, and to relate the assumptions of the theory to those that might be made about other perceptual modes. According to the ..."

to the revised theory, phonetic information is perceived in a biologically distinct system, a ‘module ’ specialized to detect the intended gestures of the speaker that are the basis for phonetic categories. Built into the structure of this module is the unique but lawful relationship between the gestures
BIO-INSPIRED CONTROLLABLE ADHESIVE
"... Geckos, as well as many species of insect, have evolved a robust reversible adhesion mechanism, enabling them to traverse rough, smooth, vertical or inverted surfaces. The extraordinary climbing ability of geckos has been attributed to the fine structure of their toe pads which contain arrays of tho ..."

Abstract—This paper presents the design and experimental results of a cochlea filter in analog very large scale integration (VLSI) which highly resembles physiologically measured response of the mammalian cochlea. The filter consists of three specialized sub-filter stages which respectively provide ..."

, the filter can be configured to operate with center fre-quencies from 31 Hz to 8 kHz. The filter is order, consumes power and occupies chip area. A parallel bank of the proposed filter can be used as the front-end in hearing prosthesis devices, speech processors as well as other bio-inspired auditory systems
