Developing interactive ways to teach about concepts such as complementation can be difficult. This approach, supported by learning data, uses blind cavefish as an example

Cross-Regional Gradient of Dendritic Morphology in Isochronically-Sourced Mouse Supragranular Pyramidal Neurons

Architectonic heterogeneity in neurons is thought to be important for equipping the mammalian cerebral cortex with an adaptable network that can organize the manifold totality of information it receives. To this end, the dendritic arbors of supragranular pyramidal neurons, even those of the same class, are known to vary substantially. This diversity of dendritic morphology appears to have a rostrocaudal configuration in some brain regions of various species. For example, in humans and non-human primates, neurons in more rostral visual association areas (e.g., V4) tend to have more complex dendritic arbors than those in the caudal primary visual cortex. A rostrocaudal configuration is not so clear in any region of the mouse, which is increasingly being used as a model for neurodevelopmental disorders that arise from dysfunctional cerebral cortical circuits. Therefore, in this study we investigated the complexity of dendritic arbors of neurons distributed throughout a broad area of the mouse cerebral cortex. We reduced selection bias by labeling neurons restricted to become supragranular pyramidal neurons using in utero electroporation. While we observed that the simple rostrocaudal position, cortical depth, or even functional region of a neuron was not directly related to its dendritic morphology, a model that instead included a caudomedial-to-rostrolateral gradient accounted for a significant amount of the observed dendritic morphological variance. In other words, rostrolateral neurons from our data set were generally more complex when compared to caudomedial neurons. Furthermore, dividing the cortex into a visual area and a non-visual area maintained the power of the relationship between caudomedial-to-rostrolateral position and dendritic complexity. Our observations therefore support the idea that dendritic morphology of mouse supragranular excitatory pyramidal neurons across much of the tangential plane of the cerebral cortex is partly shaped by a developmental gradient spanning several functional regions

Rationell verarbeitbare Hochleistungswerkstoffe auf der Basis von Thermoplasten und niedrig schmelzenden Glaesern fuer innovative Elektronikbauteile Abschlussbericht

Electronic parts are often produced with plastics containing additives like glass or metal fibers, microballs, and carbon black. However, these solid additives may cause degradation of the polymers in course of processing. Therefor, polymer/additive compounds have been prepared, where both constituents are in the molten state during compounding. Thus, machine corrosion may be reduced additionally. Experiments have been carried out with PES and PPS, filled with up to 60% powder of low-melting alkali-zinc-phosphate glasses, that were compounded in the kneader and in the twin-screw extruder, and injection molded. Reinforced moldings with well-dispersed glass phases and defined morphologies could be obtained, and preparation of reinforced miniaturized electronic parts can be possible.SIGLEAvailable from TIB Hannover: F03B603 / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Bildung und Forschung, Berlin (Germany)DEGerman
