Patterning Molecules Multitasking in the Nervous System
Classical patterning molecules that were previously implicated in controlling cell fate choices in the nervous system have recently been shown to play additional roles in axon guidance and synaptogenesis. Bone morphogenetic proteins (BMPs), Sonic hedgehog (Shh), Wnts, and fibroblast growth factors (FGFs) all participate in multiple acts of controlling neuronal circuit assembly. Depending on the...
متن کاملMultitasking behavior
This chapter does not attempt to furnish an overview of multitasking research in every scientific discipline. Rather, we highlight the importance of multitasking in the cognitive and information sciences and the need for further research on multitasking, particularly within the context of information behavior. Why are we interested in multitasking? Why is multitasking an important theoretical a...
متن کاملHuman multitasking
Humanmultitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. The term is derived from computer multitasking. An example of multitasking is taking phone calls while typing an email. Multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention. However, studie...
متن کاملMultitasking associative networks.
We introduce a bipartite, diluted and frustrated, network as a sparse restricted Boltzmann machine and we show its thermodynamical equivalence to an associative working memory able to retrieve several patterns in parallel without falling into spurious states typical of classical neural networks. We focus on systems processing in parallel a finite (up to logarithmic growth in the volume) amount ...
متن کاملModeling Multitasking Users
This paper describes an algorithm to cluster and segment sequences of low-level user actions into sequences of distinct high-level user tasks. The algorithm uses text contained in interface windows as evidence of the state of user–computer interaction. Window text is summarized using latent semantic indexing (LSI). Hierarchical models are built using expectation–maximization to represent users ...
