Cell Study Reveals How Head Injuries Lead to Serious Brain Diseases

UCLA biologists have discovered how head injuries are adversely affecting individual cells and genes that can lead to serious brain disorders. The life scientists provide the first cell "atlas" of the hippocampus-the part of the brain that helps regulate learning and memory when it is affected by traumatic brain injury. The team also proposes candidates for treating brain diseases associated with traumatic brain injuries, such as Alzheimer's disease and post-traumatic stress disorder

Cognitive Decline—Radiation—Brain Tumor Prevented By Temporarily Shutting Down Immune Response

Treating brain tumors comes at a steep cost, especially for children. More than half of patients who have radiation therapy for these tumors experience an irreversible cognitive decline , a side effect that has particularly damaging consequences for younger patients. Up to now, scientists had been unable to test potential strategies to prevent this problem because there were no laboratory models that faithfully captured the clinical lifecycle of brain tumors

Multiple sclerosis: Accumulation of B cells Triggers Nervous System Damage

B cells are important in helping the immune system fight pathogens. However, in the case of the neurological autoimmune disease multiple sclerosis (MS), they can damage nerve tissue. When particular control cells are missing, too many B cells accumulate in the meninges, resulting in inflammation of the central nervous system. A team from the Technical University of Munich (TUM) demonstrated the process of using animal and patient samples.

Bipolar Structure For Nerve Cell Migration

The cerebral cortex is responsible for a large number of complex brain functions, ranging from the perception of sensory stimuli through alertness, memory, and language to consciousness. Neurobiologists at the Max Planck Institute for Experimental Medicine in Göttingen have decoded a new regulatory principle that controls the development of the complex neuronal architecture in the cerebral cortex

Extracellular Vesicles Help Pass Information Between Cells and Onto Offspring

New studies reveal that small, membrane-bound particles transported between cells have wide-ranging and long-term effects in the brain and throughout the body, from helping neurons communicate to passing the effects of stress onto the next generation. Such extracellular vesicles released from the brain into the blood can also provide a window into brain pathology to help with disease diagnosis. The findings were presented at Neuroscience 2018

Making Moves to Understand Cognitive Function in the Brain

The cerebellum, a structure found in the back of the skull, is known to be important for the control of movement, while the frontal cortex is responsible for cognitive functions such as short-term memory and decision making. However, as the scientists continue to unlock the mystery of how billions of neurons in the brain interact, it is becoming more apparent that it is not that black and white
