Cortical Source Localization 1 Running Head: Infant Cortical Source Localization Cortical Source Localization of Infant Cognition
Neuroimaging techniques such as positron emission topography (PET) and functional magnetic resonance imaging (fMRI) have been utilized with older children and adults to identify cortical sources of perceptual and cognitive processes. However, due to practical and ethical concerns, these techniques cannot be routinely applied to infant participants. An alternative to such neuroimaging techniques...
متن کاملnear-field source localization in nonhomogeneous environments
source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o
متن کاملBiomimetic Sound-Source Localization
Sound-source localization systems typically comprise free-field microphone arrays. In nature, directional acoustic sensing evolved to rely on diffraction about the head with only two ears. For localization, the brain uses the resultant frequency-dependent acoustic phase and intensity differences between the two ears. We conceive a biomimetic artificial head with microphones placed on its surfac...
متن کاملTransient Noise Source Localization
Conventional beamforming systems for noise source localization are mostly based on frequency domain calculations. Additionally, narrowband assumptions concerning signal characteristics are often made to simplify the calculations, i.e. to be able to express a single time delay as a sole phase shift in the frequency domain as well. If necessary, a broadband system is then modeled as a composition...
متن کاملSource Localization and Beamforming
Distributed sensor networks have been proposed for a wide range of applications. The main purpose of a sensor network is to monitor an area, including detecting, identifying, localizing, and tracking one or more objects of interest. These networks may be used by the military in surveillance, reconnaissance, and combat scenarios or around the perimeter of a manufacturing plant for intrusion dete...
