Genes alone don't determine how the cerebral cortex grows into separate functional areas. Input from the thalamus is also crucially required, a new study suggests.
A new study describes the vascular architecture within the cerebral cortex, exploring what the structure means for neuroimaging and the onset of dementia.
Future research into the underlying causes of neurological disorders such as autism, epilepsy and schizophrenia, should greatly benefit from a first-of-its-kind atlas of gene-enhancers in the cerebrum (telencephalon). This new atlas identifies and locates thousands of gene-regulating elements in a region of the brain that is of critical importance for cognition, motor functions and emotion.
A new finding turns one of the basics of neurobiology on its head, demonstrating that it is possible to turn one type of already differentiated neuron into another within the brain.
Researchers report that low blood and oxygen flow to the developing brain does not, as previously thought, cause an irreversible loss of brain cells, but rather disrupts the cells’ ability to fully mature.
Researchers solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain.
Scientists at the Allen Institute for Brain Science reported that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings stem from the first deep and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas.
A neuron’s fate was thought to be determined by the timing of its birth date. Neuroscientists recently showed that there is a distinct stem cell progenitor that gives rise to upper layer neurons, regardless of birth date or place.
