The diversification of the development in humancomputer interaction provides users more and more interactive experience which is totally different than usual. As one of the sense organs that serve as a proxy for human attention and intention, we can give users better interaction closer to their need by observing the change of the eyes. This paper proposes a low-cost system, using a non-infrared...

The biological function of the ampullae of Lorenzini of elasmobranch fish remains uncertain, although by now there is considerable evidence concerning the different types of stimuli capable of eliciting responses in the sensory nerves. The ampullae are sensitive to changes of temperature of less than o-i° C. (Sand, 1938), a sensitivity that would normally justify their description as thermorece...

“Imagination is what makes our sensory experience meaningful, enabling us to interpret and make sense of it, whether from a conventional perspective or from a fresh, original, individual one. It is what makes perception more than the mere physical stimulation of sense organs. It also produces mental imagery, visual and otherwise, which is what makes it possible for us to think outside the confi...

The central hypothesis put forth by Zangari and Censor in ‘Spectral Representations’ is that “the spatiotemporal description of the world is not unique.” To support this hypothesis, Zangari and Censor utilize the Fourier Transform, a mathematical tool that is used to transform functions from the spatial or temporal domain to the spectral (i.e., frequency) domain. Zangari and Censor propose that...

A new model, conceptually informed by the embryology and evolutionary biomechanics of vertebrate movement patterns, describes fields of interacting contractility. Each contractile field is modelled as embedding a primary sense organ. Contractile fields are whole organism in scope and are drawn from core mammalian movement patterns such as flexing/extending, lateral flexing, twisting left/right,...

The aim of this follow-up performed in a period of three years (1997-1999) was to assess the morbidity rate among children (0-17 years) and adults (18 years and above) from housing estates Sarafovo, Izgrev, Zornitsa and party Slaveykov, located close to the airport of Bourgas and compare it to population living at more distance from the airport (town centre). It was found that the prevalence of...

The crossing of nerve tracts from one hemisphere in the brain to the contralateral sense organ or limb is a common pattern throughout the CNS, which occurs at specialised bridging points called decussations or commissures. Evolutionary and teleological arguments suggest that midline crossing emerged in response to distinct physiological and anatomical constraints. Several genetic and developmen...

Lateral line is a system of sense organs that can aid fishes to maneuver in a dark environment. Artificial lateral line (ALL) imitates the structure of lateral line in fishes and provides invaluable means for underwater-sensing technology and robot fish control. This paper reviews ALL, including sensor fabrication and applications to robot fish. The biophysics of lateral line are first introduc...

Almost all life histories are phenotypically plastic: that is, life-history traits such as timing of breeding, family size or the investment in individual offspring vary with some aspect of the environment, such as temperature or food availability. One approach to understanding this phenotypic plasticity from an evolutionary point of view is to extend the optimality approach to the range of env...
