The contemporary wonder of sciences and engineering has recently refocused on the beginning point of: how the brain processes internal and external information autonomously and cognitively rather than imperatively like conventional computers. Cognitive Informatics (CI) is a transdisciplinary enquiry of computer science, information sciences, cognitive science, and intelligence science that investigates the internal information processing mechanisms and processes of the brain and natural intelligence, as well as their engineering applications in cognitive computing. This paper reports a set of eight position statements presented in the plenary panel of IEEE ICCI’10 on Cognitive Informatics and Its Future Development contributed from invited panelists who are part of the world’s renowned researchers and scholars in the field of cognitive informatics and cognitive computing.

The aim of the present study was to examine the effects of an exercise of moderate intensity (60% of maximal aerobic power) on specific information-processing mechanisms. 22 students completed 3 10-min. exercise bouts on a bicycle ergometer. Concomitantly, participants performed six manual choice-reaction tasks manipulating task variables (Signal Intensity, Stimulus–Response Compatibility, and Time Uncertainty) on two levels. Reaction tests, randomly ordered, were administered at rest and during exercise. A significant underadditive interaction between Time Uncertainty and exercise was found for the highest quartiles of the distribution of reaction times. No other interaction effects were obtained for the other variables. These results reasonably support that moderate aerobic exercise showed selective rather than general influences on information processing.

We consider an integrate-and-fire element subject to randomly perturbed synaptic input and an electrically coupled ensemble of such elements. The latter is interpreted as either a model of electrically coupled population of neurons or a multicompartment model of a dendrite. Random fluctuations blur the input signal and cause false responses in the system dynamics. For instance, under the influence of noise, the system may respond with an action potential to a subthreshold stimulus. We show that the responses of the elements within the network are more reliable than the responses of the same elements in isolation. Specifically, we show that the variances of the stochastic processes generated by the coupled model can be made arbitrarily small (i.e., the network responses can be made arbitrarily accurate) by increasing the number of elements in the network and the strength of electrical coupling. Our results suggest that the organization of cells in electrically coupled groups on the network level, or the dendritic morphology on the cellular level, may be involved in the filtering noise and therefore may play an important role in the information processing mechanisms operating on the network or cellular level respectively.

Purpose The purpose of this paper is to examine how information-processing mechanisms between nominating committees (NCs), incumbent executives, board chairs, and shareholders affect the comprehensiveness of executive succession processes. Design/methodology/approach The authors employ an explanatory multiple-case study that comprises eight CEO and CFO succession cases in large German publicly traded firms. Findings The findings reveal that comprehensiveness is determined by four key information-processing mechanisms: the effectiveness of NC’s information sharing, absorbing disagreement, and integrating heterogeneous opinions; board chair leadership (i.e. an apprentice board leadership structure in association with the board chair’s openness to ideas); the breadth and depth of information sharing between executives and NCs; and the extent and timing to which major shareholders influence succession processes. Research limitations/implications The authors summarize the findings in a conceptual framework and develop a set of propositions to guide future research on the topic. Such studies may want to test the suggestions in a quantitative way, preferably in a multinational context. Originality/value The authors’ emerging conceptual framework contributes a set of information-processing variables by which NCs engage in comprehensive executive successions with incumbent executives, board chairs, and major shareholders and offers a multiechelon approach to study executive successions.

Abstract At present, there is a growing demand for radio navigation systems, ranging from pedestrian navigation to consumer behavior analysis. These systems have been successfully used in many applications and have become very popular in recent years. In this paper we present a review of selected wireless positioning solutions operating in both indoor and outdoor environments. We describe different positioning techniques, methods, systems, as well as information processing mechanisms

AbstractWe test the feasibility of an optically pumped magnetometer-magnetoencephalographic (OP-MEG) system for the measurement of human cerebellar activity. This is to our knowledge the first study investigating the human cerebellar electrophysiology using OPMs. As a proof of principle, we use an air-puff stimulus to the eyeball in order to elicit cerebellar activity that is well characterised in non-human models. In three subjects, we observe an evoked component at approx. 50ms post-stimulus, followed by a second component at approx. 85-115 ms post-stimulus. Source inversion localises both components in the cerebellum, while control experiments exclude potential sources elsewhere. We also assess the induced oscillations, with time-frequency decompositions, and identify the source in the occipital lobe, a region expected to be active in our paradigm. We conclude that the OP-MEG technology offers a promising way to advance the understanding of the information processing mechanisms in the human cerebellum.
