When multistable displays (stimuli consistent with two or more equally plausible perceptual interpretations) are presented intermittently, their perceptions are stabilized by sensory memory. Independent memory traces are generated not only for different types of multistable displays (Maier, Wilke, Logothetis, & Leopold, Current Biology 13:1076-1085, 2003), but also for different ambiguous featu...

Introduction: The major research data and findings related to aging among persons with developmental disabilities are discussed. Topics addressed include prevalence and mortality rates, as well as the effects of aging on the sensory systems, the neuromusculoskeletal system and the cardiopulmonary system. The discussion also focuses on the clinical implications of these changes among aging indiv...

A continuing challenge for prostheses developers is to replace the sensory function of the hand. This includes tactile sensitivity such as finger contact, grip force, object slippage, surface texture and temperature, as well as proprioceptive sense. One approach is sensory substitution whereby an intact sensory system such as vision, hearing or cutaneous sensation elsewhere on the body is used ...

Context: It is generally assumed that learning is restricted to neural and immune systems. However, the systemic memory hypothesis predicts that all dynamical systems that contain recurrent feedback loops store information and energy to various degrees. Sensitive transplant patients may evidence personal changes that parallel the history of their donors. Objective: To evaluate whether changes f...

We present active object categorization experiments with a real humanoid robot. For this purpose, the training algorithm of a recurrent neural network with parametric bias has been extended with adaptive learning rates. This modification leads to an increase in training speed. Using this new training algorithm we conducted three experiments aiming at object categorization. While holding differe...

With increasing age changes of sensory, motor, and cognitive functions take place, that can have an impact on driving and may induce driving problems and errors, that are partly registered in the ”Verkehrszentralregister (VZR)“. In order to cope with functional deficits and to continue driving, elderly often activate compensation mechanisms. The present study investigated in which respect old d...

The aim of the research was analysis of rice producers’ perceptions of participatory communication in the use of integrated pest management (IPM). Research population was consisted of rice producers in the west of Mazandaran province (N=16126), whose 187 ones were selected using Cochran’s formula. Data were gathered by systematic random sampling method. The instrument for data collection was a ...

introduction: barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. on the other hand, norepinephrine (ne) and locus coeruleus, which is the main source of ne, influenced response properties of cortical barr...
