A new system for distinguishing cell types in the brain, has been announced by the Blue Brain Project. It represents an algorithmic classification method that the researchers say will benefit the entire field of neuroscience. “For nearly 100 years, scientists have been trying to name cells. They have been describing them in the same way… Read more

Split seconds before we recall memories of past experiences, tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval, a study of epilepsy patients suggest. “We showed for the first time that ripples may be the neural substrates through which the… Read more

The thickness of the brain’s outer layer influences how individual neurons process information, new work from the University of Queensland indicates. The findings challenge the understanding of how brain circuits function throughout the brain. The outer layer of the brain (the cortex), is made up of many smaller microcircuits of brain cells, each consisting of… Read more

Beta rhythms are waves of brain activity with an approximately 20 Hz frequency. They accompany vital fundamental behaviors such as attention, sensation and motion and are also associated with certain disorders such as Parkinson’s disease. Scientists have debated how the spontaneous waves emerge, but have not yet established whether the waves are just a byproduct… Read more

Using a technique that rapidly freezes the brain, preserving its true structure, scientists at Ecole Polytechnique Fédérale de Lausanne have shown that the brain is not as compact as has been thought. Typically, scientists must use electron microscopes to study the fine structure of the brain, including its connections between neurons, the synapses. But the… Read more
