An ever-growing epidemic, obesity is a chronic medical condition where excess body fat has accumulated to the point it may cause a multitude of health disorders. Several studies have also … Continue Reading Visceral fat delivers a signal to the brain that impairs cognition.
Acting as natural computers, our brains contain trillions of cells to store memory and control the body’s functions and emotions. Around one in ten of the countless cells in the … Continue Reading Microglia filmed shaping synapses for the first time.
Pain hypersensitivity can spread to unaffected body regions immediately surrounding the initial insult. Sometimes it can even spread to the opposite site of the body or to large body areas … Continue Reading Pain-initiating function of glial cells identified for the first time.
NMDA glutamate receptors function as receptors which bond with glutamates, and are known to be deeply involved in memory and learning. In order for memories to be created inside the … Continue Reading Study identifies microtubule protein crucial for synaptic plasticity and memory.
Excessive alcohol-use is the third leading risk factor for disease following tobacco and blood pressure. The most important include peripheral neuropathy, brain damage, alcoholic liver disease, and nutritional and metabolic … Continue Reading Hormone and neurotransmitter systems disturbed in alcoholics’ brains.
Memories are formed at structures in the brain known as dendritic spines which communicate with other brain cells via synapses. It is known that the number of these brain connections … Continue Reading Study identifies cause of dendritic pruning defect linked to autism and schizophrenia.
Whenever a person learns something new or is affected by their experiences it’s because synapses, the connections between neurons in the brain, have changed. Sometimes new synapses are made, and … Continue Reading Study shows how astrocytes help control synapse strength and plasticity.
The human brain has a prodigious demand for energy, it uses 20 to 30% of the body’s energy budget. In the course of normal aging, in people with neurodegenerative diseases … Continue Reading Researchers use dietary supplement to re-energize aging brains in animal model.
The incidence of HIV-associated dementia has declined dramatically since the introduction of potent combined antiretroviral therapy; however, milder forms of HIV-associated neurocognitive disorders (HAND) persist. Some 30 to 50 % of … Continue Reading Study shows how neural networks adapt to the presence of a toxic HIV protein.
The auditory nerve is comprised of thousands of tiny nerve fibers responsible for transmitting sound to and from the ear and the brain. Recent discoveries have shown that they are … Continue Reading Researchers identify previously unknown compensatory brain amplifier for hear loss.
Another year of growth for the Healthinnovations, many great breakthroughs, with previously immature technologies and disciplines coming into their own, as crucial parts of global innovation. For instance, biomarkers have … Continue Reading The Top Ten Healthinnovations of 2015.
It is known that the neurons of the human brain communicate with each other through specialized structures called synapses. A synapse consists of a presynaptic terminal of one neuron … Continue Reading Previously unknown molecule critical to synaptic transmission identified.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid (lactate) has been … Continue Reading Study confirms 20 year-old hypothesis on the brain using lactate for energy.
The brain controls most of a person’s behaviour and changes in how brain areas work and communicate with each other can alter this behaviour and lead to impairments associated with … Continue Reading New neuroimaging technique shows how the ‘social brain’ is impaired in autism.
Differences in the size and structure of certain brain areas have been found in some adults diagnosed with schizophrenia. Early findings came from the discovery of enlarged ventricles in people … Continue Reading Neuroimaging matches specific schizophrenia behaviour to the brain’s anatomy.
Cognitive function is known to change during normal aging and in age-related disease such as Alzheimer’s disease. Although the exact cause for age-related cognitive decline is not clear, recent studies … Continue Reading Researchers combat memory loss by enhancing brain function in animal model.
