Increased Brain Signal Variability Accompanies Lower Behavioral Variability in Development
As the brain matures, its responses become optimized. Behavioral measures show this through improved accuracy and decreased trial-to-trial variability. The question remains whether the supporting brain dynamics show a similar decrease in variability. We examined the relation between variability in single trial evoked electrical activity of the brain (measured with EEG) and performance of a face...
متن کاملBias Crime Statutes: a Qualified Liberal Defense
Since American legislatures began passing bias crime statutes (which set more severe penalties for crimes committed from biased motives) in the 1980s, many legal philosophers have argued that such statutes are unjust on the grounds that they punish character traits and feelings rather than actions and intentions. It is unjust to punish character traits and feelings, these authors have supposed,...
متن کاملRelating brain signal variability to knowledge representation
We assessed the hypothesis that brain signal variability is a reflection of functional network reconfiguration during memory processing. In the present experiments, we use multiscale entropy to capture the variability of human electroencephalogram (EEG) while manipulating the knowledge representation associated with faces stored in memory. Across two experiments, we observed increased variabili...
متن کاملTrack-to-Track Association and Bias Removal
This paper develops methods for associating two sets of sensor tracks in the presence of missing tracks and translation bias. Key results include (1) Extension of the Maximum A Posteriori Probability method of matching tracks to use feature information as well as kinematic information; (2) translation bias removal techniques that are computationally tractable for large numbers of tracks, and ef...
متن کاملSpatiotemporal Dependency of Age-Related Changes in Brain Signal Variability
Recent theoretical and empirical work has focused on the variability of network dynamics in maturation. Such variability seems to reflect the spontaneous formation and dissolution of different functional networks. We sought to extend these observations into healthy aging. Two different data sets, one EEG (total n = 48, ages 18-72) and one magnetoencephalography (n = 31, ages 20-75) were analyze...
