The Other Brain Cells: New Insights into What Glial Cells Do

31.01.2021 Health Problems

Skip to: Astrocytes Oligodendrocytes and NG2 Cells Microglia Other Functions Summary Glial cells are non-neuronal cells found within the brain and the rest of the nervous system. There are approximately 60 billion glia to 16 billion neurons within the cortex, but only 16 billion glia to 69 billion neurons in the cerebellum. Overall, there are roughly the same number of […]

Deep inside the brain: Mapping the dense neural networks in the cerebral cortex

25.10.2019 Health Problems

Mammalian brains, with their unmatched number of nerve cells and density of communication, are the most complex networks known. While methods to analyze neuronal networks sparsely have been available for decades, the dense mapping of neuronal circuits is a major scientific challenge. Researchers from the MPI for Brain Research have now conducted connectomic mapping of brain tissue from the cerebral […]

Thalamus and cerebral cortex interactions influence the decision on sensory perceptions

02.04.2019 Health Problems

When we receive a stimulus, sensory information is transmitted by the afferent nerves to the thalamus, which in turn, like a relay, forwards the information to the sensory cortex to process it and consciously perceive the stimulus. But, does this information travel only in the thalamus-cortex direction? And, is this journey a determining factor in the subsequent conscious perception of […]
