Neurodevelopmental disorders may be rooted in genetics and mitochondrial deficits

Under-connectivity, or too few connections in the brain, is the underlying cause of brain disorders like autism and schizophrenia, according to a recent study from investigators at the George Washington University (GW) Institute for Neuroscience. The study, published in Neuron, provides the first evidence showing that individual nerve cells fail to make the right number of connections. The reason for this deficit is limited growth of key nerve cells in the cerebral cortex during early development, due to both genetics and mitochondrial dysfunction.

Gold makes invisible surfaces visible in CT

Today, the three-dimensional visualization and analysis of biological samples using computer tomography (CT) is a routine procedure. However, in the past, it was very difficult to visualize the fine surface details of many organisms. Scientists at the Universities of Cologne and Bonn and the Zoological Research Museum Alexander Koenig—Leibniz Institute for Animal Biodiversity in Bonn have now developed a new method to digitally capture and display even the finest surface structures. To achieve this, they coated the samples with a thin layer of gold, a technique that has previously only been used in scanning electron microscopy. Besides the implementation in biological sciences, the new method also holds promise for more practical areas of application such as material sciences or quality control in manufacturing companies. The research results have now been published in the Journal of Anatomy.
