A balance equation determines a switch in neuronal excitability. [PDF]

PLoS Computational Biology, 2013
We use the qualitative insight of a planar neuronal phase portrait to detect an excitability switch in arbitrary conductance-based models from a simple mathematical condition. The condition expresses a balance between ion channels that provide a negative

Evaluation of a vibrotactile feedback device for spatial guidance

, 2011
In the present study, a vibrotactile feedback device for spatial guidance was evaluated in a tracking task paradigm. Participants (N = 18) had to translate and rotate virtual objects according to the vibrotactile vs.

Multimodal measurements enhance insights into emotional responses to immediate feedback

Frontiers in Psychology
Adaptive learning technologies often provide students with immediate feedback on task performance. This feedback can elicit various emotional responses, which, in turn, influence learning. Most recent studies capture these emotions by single data streams,

Physiological Positive Feedback Mechanisms

American Journal of Biomedical Sciences, 2011
In positive feedback mechanisms, the response to a stimulus does not stop or reverse it but instead keeps the sequence of events going up. At first glance, this would appear to be a counter to the principle of homeostasis, since a positive feedback loop has no obvious means of stopping.

On the global attractor of delay differential equations with unimodal feedback

, 2009
We give bounds for the global attractor of the delay differential equation x(over dot) (t) = -mu x(t) + f(x(t - tau)), where f is unimodal and has negative Schwarzian derivative.

Affective feedback: an investigation into the role of emotions in the information seeking process [PDF]

, 2008
User feedback is considered to be a critical element in the information seeking process, especially in relation to relevance assessment. Current feedback techniques determine content relevance with respect to the cognitive and situational levels of ...
