We present an attractor based dynamics that autonomously generates trajectories with stable timing (limit cycle solutions), stably adapted to changing online sensory information. Autonomous differential equations are used to formulate a dynamical layer with either stable fixed points or a stable limit cycle. A neural competitive dynamics switches between these two regimes according to sensorial...

Second order neurons in the nucleus tractus solitarius (NTS) process and integrate the afferent information from arterial baroreceptors with high fidelity and precise timing synaptic transmission. Since 2nd-order NTS neurons receiving baroreceptors inputs are relatively well characterized, their electrophysiological profile has been accepted as a general characteristic for all 2nd-order NTS neu...

Affordance Modelling and Simulation 2 Abstract Recently, Wells (2002) suggested using the formalism of the Turing Machine to describe the concept of affordance. Even though the author has shown that the generic properties of the concept were taken into account in this modelling, no research has yet attempted to model adaptive behaviour in an ecosystem with this formalism. In this paper, we prop...

In this paper a control scheme is proposed for anticipatory and discrete event sensory motor driven. The control system elaborates a sensorymotor program based on its internal data and a high level objective. The global system implements several biological models in each one of its subsystems. One of the novelties of this work is the structure of the sensory-motor algorithms which are based on ...

The introduction presents the main countries producing duck meat and the different species and rearing systems used in production. The review is then divided into two parts. The first part concerns meat quality. The evolution of duck meat post-mortem is described. The effects of high muscle development on technological and sensorial quality are also presented. Finally, the influences of the mai...

Apple quality was investigated in the scab-resistant 'Liberty', 'Santana', and 'Topaz' cultivars and the scab-susceptible 'Golden Delicious' cultivar. Trees subjected to the same crop load were cultivated using either an organic (ORG) or an integrated production (IP) system. Physicochemical properties, phenolic content, and sensorial quality of fruit from both systems were compared. There were ...

Acceptance of food is basically the result of the interaction between food and human and it depends not only on the product characteristics but also on those of each consumer. The main objective of this work is to analyse how the acceptability of milk and soymilk vanilla beverages is influenced by demographic characteristics, consumer habits and individual preferences and the sensorial properti...

Haptic feedback is a crucial sensorial modality in virtual reality interactions. Haptics means both force feedback (simulating object hardness, weight, and inertia) and tactile feedback (simulating surface contact geometry, smoothness, slippage, and temperature). Providing such sensorial data requires desk-top or portable special-purpose hardware called haptic interfaces. Modeling physical inte...

Herpes zoster primarily affects the posterior root ganglions and sensorial nerve fibers, and causes vesicular skin eruptions, radicular pain and loss of sensorial function along the distribution of the affected ganglion. Motor involvement can also be observed. When classical cutaneous lesions are present, the motor paresis consequent to herpes zoster is easily diagnosed. However, diagnosis beco...

An evaluation of the capacity of a lyophilized water extract of borage leaves to delay the lipid oxidation process in dry fermented sausages enriched with ω-3 PUFAs has been performed. 340 ppm of lyophilized extract showed an antioxidant capacity equivalent to 200 ppm of a butylhydroxyanisol (BHA) and butylhydroxytoluene (BHT) mixture. Two batches of dry fermented sausages enriched in ω-3 PUFA ...
