Sleep, Memory & Brain Rhythms.
Sleep occupies roughly one-third of our lives, yet the scientific community is still not entirely clear on its purpose or function. Existing data point most strongly to its role in memory and homeostasis: that sleep helps maintain basic brain functioning via a homeostatic mechanism that loosens connections between overworked synapses, and that sleep helps consolidate and re-form important memor...
متن کاملThe survey of fluctuations of attention on circadian and weekly rhythms among high school students
Introduction: Human cognitive activities are affected by the time of doing homework, biologic rhythms and interaction among them. Method: this research accomplished to specify the fluctuation patterns of daily and weekly cycles of the students attention. The research method was correlation. The statistical population of this study were 45 female students in 11th grade from a high school in hu...
متن کاملShared Visual Attention and Memory Systems in the Drosophila Brain
BACKGROUND Selective attention and memory seem to be related in human experience. This appears to be the case as well in simple model organisms such as the fly Drosophila melanogaster. Mutations affecting olfactory and visual memory formation in Drosophila, such as in dunce and rutabaga, also affect short-term visual processes relevant to selective attention. In particular, increased optomotor ...
متن کاملBrain dynamics of attention and working memory engagement in subitizing.
This study addressed the engagement of attention and working memory, as inferred from electrophysiological measurements, in the processing of small sets of objects. We recorded N2pc and CDA, two lateralized components of the EEG signal associated respectively with individuation and visual working memory, while participants enumerated a variable number (1-9) of uniquely colored targets among dis...
متن کاملLocation of brain rhythms and their modulation by preparatory attention estimated by current density.
To test the hypothesis that there is a functional modulation of conventional EEG bands associated with preparatory attention, putative changes in the spontaneous brain rhythms and their associated cerebral sources were addressed. The goals of the present report were, first, to find the brain areas with maximal rhythmic activity before warning and imperative stimuli in a classic contingent negat...
