A stereotyped series of behavioural changes occurs in preparation for pupation in Manduca sexta. Feeding declines over an 8-h period, after which the larva coats its body with a labial gland secretion. The animal then begins a 10- to 30-h wandering behaviour during which it constructs a pupation chamber underground. Wandering behaviour starts during a specific temporal gate which is determined ...

Wandering spleen is a rare entity with the incidance of %0.2 (1), Here in we presented a 30-year-old woman with wandering spleen that leads to splenic volvulus and congestion with splenic venous thrombus and portal venous thrombus.

Experiences such as mind-wandering illustrate that cognition is not always tethered to events in the here-and-now. Although converging evidence emphasises the default mode network (DMN) in mind-wandering, its precise contribution remains unclear. The DMN comprises cortical regions that are maximally distant from primary sensory and motor cortex, a topological location that may support the stimu...

Successful learning requires that individuals integrate information from the external environment with their own internal representations. In this article, we consider the role that mind wandering plays in education. Mind wandering represents a state of decoupled attention because, instead of processing information from the external environment, our attention is directed toward our own private ...

OBJECTIVE To characterize wandering, or elopement, among children with autism spectrum disorder (ASD) and intellectual disability. STUDY DESIGN Questions on wandering in the previous year were asked of parents of children with ASD with and without intellectual disability and children with intellectual disability without ASD as part of the 2011 Survey of Pathways to Diagnosis and Services. The...

Successful learning requires that individuals integrate information from the external environment with their own internal representations. In this paper we consider the role that mind-wandering plays in education. Mind-wandering represents a state of decoupled attention because instead of processing information from the external environment our attention is directed to our own private thoughts ...

Cognitive psychology and cognitive neuroscience have recently developed a keen interest in the phenomenon of mind-wandering. People mind-wander frequently, and mind-wandering is associated with decreased cognitive performance. But why do people mind-wander so much? Previous investigations have focused on cognitive abilities like working memory capacity and attention control. But an individual's...

Finite-time Lyapunov exponents of generic chaotic dynamical systems fluctuate in time. These fluctuations are due to the different degree of stability across the accessible phase space. A recent numerical study of spatially extended systems has revealed that the diffusion coefficient D of the Lyapunov exponents (LEs) exhibits a nontrivial scaling behavior, D(L)~L(-γ), with the system size L. He...

Tests of working memory capacity (WMC) and fluid intelligence (gF) are thought to capture variability in a crucial cognitive capacity that is broadly predictive of success, yet pinpointing the exact nature of this capacity is an area of ongoing controversy. We propose that mind-wandering is associated with performance on tests of WMC and gF, thereby partially explaining both the reliable correl...
