Visual sensation begins at the retina, which is the neural tissue located at the back of eyeballs. It has been known that the retina detects light using photoreceptors which are light-sensitive nerve cells.In case of retinal degenerative diseases such as retinitis pigmentosa and age-related macular degeneration, those light sensing neurons are gradually damaged, leading to […]
One of the grand quests in neuroscience is to build a precise map of the brain, charting all its neurons and the connections between them. Such a wiring diagram, called a connectome, promises to help shed light on how a collection of cells can together give rise to thoughts, memories, behaviors and myriad other functions. […]
Researchers from Universidad Politécnica de Madrid report a new method for graphic representation of neurons that visualizes the data developed by neuroscientists. A team of researchers from Universidad Politécnica de Madrid (UPM), Universidad Rey Juan Carlos (URJC) and the Cajal Institute (IC) of the Spanish National Research Council (CSIC) has published the results in Frontiers […]
Mutations in a gene known as interferon regulatory factor 6 (IRF6) that cause cleft lip and palate also are implicated in neural tube defects such as spina bifida, suggests research by an international study team published online Jan. 25, 2019, in Human Molecular Genetics. In the first weeks of fetal development the neural plate curves, […]
Data from the National Institutes of Health (NIH) indicate that approximately 50,000 people receive a diagnosis of Parkinson’s disease each year in the United States. In terms of its worldwide prevalence, studies have shown that Parkinson’s disease affects one percent of the population aged 60 and over, and it is the second most widely diagnosed […]
In those precious weeks before a woman even realizes she’s pregnant, an embryo will have already developed a neural tube, a hollow structure made of cells which will eventually become the brain and spinal cord. Now, with $3.2 million from the National Institutes of Health, UH professor of biomedical engineering Kirill Larin will tackle the […]
The function of the brain is based on the connections between nerve cells. In order to map these connections and to create the connectome, the “wiring diagram” of a brain, neurobiologists capture images of the brain with the help of three-dimensional electron microscopy. Up until now, however, the mapping of larger areas has been hampered […]
