Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remains in the brain that keeps on producing new neurons throughout life. However, the question arises as to whether these new neurons really support brain function? And if so, can we improve […]Continue Reading ...
In ‘game-changing’ finding, bone mass rose 800% after signals were blocked in brains of mice UCLA and UC San Francisco life scientists have discovered a dramatic pattern of bone growth in female mice — research that could potentially lead to stronger bone density in women and new treatments for osteoporosis in older women. The researchers […]Continue Reading ...
To observe the deep-seated wiring of a mouse’s brain, Scherrer partnered with Schnitzer, who had developed a “miniscope” — a microscope about the length of a small paper clip, which could be affixed to a mouse’s head to record activity in its brain. They positioned the device strategically to visualize the amygdala. The mouse, alive […]Continue Reading ...
Credit: CC0 Public Domain Some neurons in the brain protect themselves from Alzheimer’s with a cellular cleaning system that sweeps away toxic proteins associated with the disease, according to a new study from Columbia University and the University of Cambridge. The study, led by neuroscientist Karen Duff, Ph.D., of Columbia University Vagelos College of Physicians […]Continue Reading ...
Electrical stimulation of the brain is common practice in neuroscience research and is an increasingly common and effective clinical therapy for a variety of neurological disorders. However, there is limited understanding of why this treatment works at the neural level. A paper published by Takashi D. Y. Kozai, assistant professor of bioengineering at the University […]Continue Reading ...
When we perceive the world around us, certain objects appear to be more noticeable than others, depending on what we do. For example, when we view a forest-covered mountain from a distance, the forest looks like a large green carpet. But as we get closer, we start noticing the individual trees, and the forest fades […]Continue Reading ...
About 3.4 million Americans, or 1.2 percent of the population, have active epilepsy. Although the majority respond to medication, between 20 and 40 percent of patients with epilepsy continue to have seizures even after trying multiple anti-seizure drugs. Even when the drugs do work, people may develop cognitive and memory problems and depression, likely from […]Continue Reading ...
A new study shows how cellular “housekeeping” protects some neurons against the toxic proteins of Alzheimer’s disease and suggests new treatment possibilities.Continue Reading ...
A researcher at the UPV/EHU-University of the Basque Country has participated in the study into the impairment of the dynamics of spines that receive information from other neurons A researcher at the UPV/EHU has participated in a study describing what it is during the early stages of Alzheimer’s that triggers the loss of dynamics and […]Continue Reading ...
The incidence of some neurological diseases–especially those related to aging, such as Alzheimer’s and Parkinson’s diseases–is increasing. To better understand these conditions and evaluate potential new treatments, researchers need accurate models that they can study in the lab. Researchers from the Salk Institute, along with collaborators at Stanford University and Baylor College of Medicine, have […]Continue Reading ...
Jan 9 2019 Mice produce new neurons in the hippocampus following a stroke that fail to develop properly, finds new research published in JNeurosci. Intervening in the production of these cells may help to mitigate stroke-induced memory impairments. Stroke has long been known to increase adult neurogenesis. Despite the proliferation of new cells in a […]Continue Reading ...
Researchers at Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with research groups in Finland, Canada, and Slovenia, have discovered a novel and unexpected function of nestin, the best known marker of neural stem cells. In the developing brain, the 3 main cell types, specifically neurons, astrocytes and oligodendrocytes, are generated from neural […]Continue Reading ...
Neurons in red are the unfit neurons that will be killed for the better functioning of the whole brain, marked in blue. Credit: Dina Coelho (CCU) Current thinking about Alzheimer’s disease is that neuronal cell death in the brain is to blame for the cognitive havoc caused by the disease. But a new study suggests […]Continue Reading ...
A mouse study shows that a single workout can activate POMC neurons (shown in green in yellow) for up to 2 days. The activity of these neurons are important regulators of blood glucose levels and energy balance. Credit: UT Southwestern Lounging around all weekend may weigh heavy on the minds of the health conscious. But […]Continue Reading ...
Credit: CC0 Public Domain It’s a maddening cycle that has affected us all: it starts with an itch that triggers scratching, but scratching only makes the itchiness worse. Now, researchers have revealed the brain mechanism driving this uncontrollable itch-scratching feedback loop. In a study publishing on December 13 in the journal Neuron, the researchers showed […]Continue Reading ...
