Inhibitory systems are essential for controlling the pattern of activity in the cortex, which has important implications for the mechanisms of cortical operation, according to a Yale School of Medicine study in Neuron.
The findings demonstrate the inhibitory network is central to controlling not only the amplitude, extent and duration of activation of recurrent excitatory cortical networks, but also the precise timing of action potentials, and, thus, network synchronization, said David McCormick, professor of neurobiology and senior author of the study.
There are two cell types in the cortex, excitatory and inhibitory. The cortex has a tendency to make recurrent excitation, and, if not properly controlled by the inhibitory system, this could lead to seizures, as is seen in epilepsy.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
