In the first of four studies, the researchers examined 54 brain cell types in 427 brain samples from a cohort of people with varying levels of cognitive impairment that has been followed since 1994. 1 The MIT team generated an atlas of gene activity patterns within the brain’s prefrontal cortex, an important area for memory retrieval.Researchers have built the world's first artificial neuron that's capable of mimicking the function of an organic brain cell - including the ability to translate chemical signals into electrical impulses, and communicate with other human cells. These artificial neurons are the size of a fingertip and contain no 'living' parts, but the team is ...

Because cell phones usually are held near the head when a person is on a call, the main concern has been whether the phones might cause or contribute to tumors in this area, including: Malignant (cancerous) brain tumors, such as gliomas. Non-cancerous tumors of the brain, such as meningiomas.

In those studies that also determined the consequences of the ablation in other cell types, only the cell numbers were quantified but not their function.Single cell assays advance the search for cell types. The recent development of high-throughput single cell transcriptomic (RNA-Seq) and epigenomic assays (mC-Seq for DNA methylation and ATAC-Seq for open chromatin) has raised expectations for a new and more detailed empirical analysis of brain cell types [].Indeed, pioneering studies, reviewed by …Every cell in a human brain contains the same sequence of DNA, but in different cell types different genes are copied onto strands of RNA for use as protein blueprints. This ultimate variation in which proteins are found in which cells—and at what levels—allows the vast diversity in types of brain cells and the complexity of the brain.During mammalian development, differences in chromatin state coincide with cellular differentiation and reflect changes in the gene regulatory landscape1. In the developing brain, cell fate ...Researchers have built the world's first artificial neuron that's capable of mimicking the function of an organic brain cell - including the ability to translate chemical signals into electrical impulses, and communicate with other human cells.
