The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Computational Modeling and Experimental Findings on Nucleosome Constraining in Mitosis

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.

Electrical Recordings Illuminate Neural Basis of Inferential Reasoning

It takes brains to infer how any two things in the world relate to each other, whether it's the way bad weather links to commuting delays or how environmental conditions lead to the evolution of species.

New Imaging Technique Offers Clearer View of Brain Function

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

New Insights into Memory Formation and Modification

The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.

Spontaneous Brain Activity Drives Early Neural Circuit Formation

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -; four legs, fur, a tail, etc. -; a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen?

Astrocytes Emerge as Key Players in Brain Health and Development

Researchers at the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) and Duke-NUS Medical School have uncovered a novel mechanism for reawakening dormant neural stem cells, which may lead to the development of new treatments for neurodevelopmental disorders like autism, cerebral palsy, and learning disabilities.

Research Unlocks Secrets of Stem Cell Retention in Bone Marrow

A discovery by a three-member Albert Einstein College of Medicine research team may boost the effectiveness of stem-cell transplants, commonly used for patients with cancer, blood disorders, or autoimmune diseases caused by defective stem cells, which produce all the body's different blood cells. The findings, made in mice, were published today in the journal Science.
