Furthermore, the introduction of asymmetry to connectivity (with feedback connections weaker than feedforward connections) enhanced the diversity of timescales.
Most students ultimately agreed that dynamics, network connectivity, hierarchical feedback systems, and large data sets are common to problems in systems biology.
The compounding effects of climate change and variability, knowledge gaps in landscape connectivity and feedbacks make the task of managing wetlands as part of a larger landscape difficult.
Knowledge gaps identified in discussions during the symposium include: identifying questions that can be usefully addressed within a framework emphasizing connectivity; identifying feedbacks that enhance and limit connectivity; and quantification – of diverse aspects of connectivity, of thresholds of connectivity, and of interactions among different types of connectivity.
Recent progress in visual neuroscience that uncovered long-range horizontal connections between cortical neurons and revealed the complex architecture of primary visual cortex and feedback connectivity led to new insights concerned with the processing of geometrical properties of visual stimuli in V1.
I am working to better understand the contribution of lateral and feedback connectivity to the response properties of visually selective neurons in the primary visual cortex.
Higher eukaryotes can thus control low rates of near irreversible cell fate decisions through a balancing act between noise and ultrahigh feedback connectivity.
Such an approach attempts to increase both theoretical and empirical verisimilitude for some key elements of complexity processes − emergence, connectivity, interdependence and feedback (Miller and Page 2007) − found throughout several disciplines across all scales of modernization and human development.
So, alterations in the intrinsic circuitry of the amygdala and anterior cingulate cortex may result in altered connectivity, deficient cingulate feedback regulation on amygdala function and abnormal processing of emotion-related stimuli in depression [11], [12].
Increasing local excitatory connectivity boosts positive feedback in cortical microcircuits and amplifies signals (Douglas et al. 1995).
