The human brain presents a powerful, low-energy computing model, made up billions of networked neurons connected by synapses which provide the memory elements. Synaptic connections in the brain can become … Continue Reading Neurologically capable neurobot a step closer to integrating nanobots into the nervous systems.
The brain controls all functions in the body and interprets information from the outside world with intelligence, creativity, emotion, and memory all governed by the central nervous system. The central … Continue Reading Researchers identify the control mechanism of synapse formation.
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.
When it comes to hearing, precision is important say researchers. Due to the fact vertebrates, such as birds and humans, have two ears, and sound-waves from either side travel different … Continue Reading Researchers map auditory brain cells for maximum hearing precision.
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.
In the brain, patterns of neural activity are perfectly balanced. The interplay between activating and inhibitory neurotransmitters ensures that the level of activity stays within the physiological range. Neuronal degeneration … Continue Reading Researchers begin to map neuroprotective pathway after epileptic seizure.
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.
Dopamine deficiency in the basal ganglia is known to cause severe motor dysfunctions such as slowness of movement, or bradykinesia, as seen in Parkinson’s disease. Dopamine binds D1 and D2 receptors … Continue Reading Study identifies the cause of slowness of movement in Parkinson’s disease.
Synaptic mitochondria are thought to be critical in supporting neuronal energy requirements at the synapse, and bioenergetic failure at the synapse may impair neural transmission and contribute to neurodegeneration. However, … Continue Reading Researchers link impaired mitochondria and a loss of ATP to neurodegeneration.
Tauopathies are neurodegenerative diseases that are signified by the presence of irregular tangle-like clumps of the protein tau that appear in the brain and accumulate during as the disease progresses. … Continue Reading Study identifies a previously unknown mechanism of neurofibrillary tangle formation.
Synapses are specialized, protein-rich cell junctions that are essential for normal brain function and are dysfunctional in many diseases and disorders of the nervous system. Synapses are made up of … Continue Reading Study identifies elusive master regulator of synaptic protein sorting.
In the first study of its kind researchers from UCLA and the University of Leicester found that neurons in a specific brain region play a key role in rapidly forming … Continue Reading First ever study records memory being encoded in individual neurons.
