Faumont, Serge and Shawn R. Lockery. The awake behaving worm: simultaneous imaging of neuronal activity and behavior in intact animals at millimeter scale. J Neurophysiol 95: 1976–1981, 2006. First published November 30, 2005; doi:10.1152/jn.01050.2005. Genetically encoded optical probes of neuronal activity offer the prospect of simultaneous recordings of neuronal activity and behavior in inta...

Epilepsy is linked to mutations in KCNQ channels. KCNQ channels including KCNQ2 and KCNQ3 are enriched in neurons, regulating action potential generation and modulation. Here, we showed that properties of KCNQ2 channel in rat hippocampal cultured neurons are regulated by ubiquitous calcium sensor calmodulin. We analyzed calmodulin function on the KCNQ2 channel in both HEK293 cells and neurons. ...

Changes in the intracellular free calcium concentration ([Ca²⁺]i) in neurons regulate many and varied aspects of neuronal function over time scales from microseconds to days. The mystery is how a single signalling ion can lead to such diverse and specific changes in cell function. This is partly due to aspects of the Ca²⁺ signal itself, including its magnitude, duration, localisation and persis...

Provenance, from the French word “provenir”, describes the lineage or history of a data entity. Provenance is critical information in the sensors domain to identify a sensor and analyze the observation data over time and geographical space. In this paper, we present a framework to model and query the provenance information associated with the sensor data exposed as part of the Web of Data using...

The area of wireless multimedia sensor networks (WMSNs) is one of the emerging and fast growing fields in the scientific world. This has brought about developing low cost, low-power and multi-function multimedia sensor nodes networks of wirelessly interconnected that are able to ubiquitously retrieve multimedia content such as video and audio streams, still images, and scalar sensor data from t...

Wireless sensor networks (WSNs) are taking a big step forward to productive deployments. Heterogeneous WSNs are gaining importance. Complex problem settings consisting of different environmental conditions require specific sensor nodes for the individual tasks resulting in heterogeneous networks. As the different types of sensor nodes may be incompatible, a more general management architecture ...

Minimization of energy consumption is a critical design requirement for most wireless sensor networks (WSNs) applications. WSNs are composed of small, energy constrained sensor nodes. The random deployment of sensor nodes in many applications requires unattended operation. The primary goal of WSNs is how to collect sensed information in energy efficient way since the energy is limited. The netw...

Wireless Sensor Networks (WSNs) are deployed with large number of small sensor devices which are highly distributed. The sensor nodes are able to organize flexibly into a multi-hop ad-hoc network. The major task of sensor nodes is to sense physical data and transmit the gathered information to one or more base stations. Reliable delivery of data is very important and has to be considered while ...

Data aggregation is a popular approach employed in wireless sensor networks (WSNs) to minimize data transmission and storage. With aggregation techniques, the monitored data is expressed in a condensed form: Therefore, instead of storing all data sensed by several nodes, the network stores a condensed value only such as the sum of these values. However, data aggregation becomes problematic when...

Wireless Sensor Networks (WSNs) are complex networks consisting of many sensors which can detect and collect sensed data. Valuable information can be extracted from the sensed data of WSNs using data mining techniques, which provide unlimited possibilities of applications, and have been the object of an increasing number of studies in recent years. This study applies ranking sequence mining to ...
