The brain is comprised of billions of brain cells, a vast network of synapses and neurons transmitting electronic impulses like many stars in an infinite universe. A crucial support system … Continue Reading New role identified for astrocytes in brain processing.
Stuttering is a neurodevelopmental disorder characterized by pauses and repeated sounds or words, which disrupt the normal flow of speech, causing great embarrassment for some sufferers. For 1 in 4 … Continue Reading Brain cell involved in stuttering identified.
Like a myriad of stars interacting with the expanse of space, the brain contains billions of interlaced and communicating neurons supported by the brain’s immune cells, known as glia. The … Continue Reading Researchers show astrocytes are crucial for establishing long-term memory in mice.
Astrocytes are the most abundant glial cells in the central nervous system (CNS) known to be involved in many roles in the brain including the composition of the blood-brain barrier, … Continue Reading Astrocytes found to have a direct role in brain plasticity.
Glial cells are immune cells found in the brain not directly involved in synaptic interactions or electrical signaling, although their supportive functions are known to play a crucial role in … Continue Reading Study identifies new key role for astrocytes in memory and learning.
Alzheimer’s disease (AD) is the most common dementia type, with no treatment to slow down the progression of this dehumanizing disease currently available. The mechanisms of AD are poorly understood … Continue Reading Astrocytes linked to Alzheimer’s disease for the first time.
Alzheimer’s disease (AD) is characterized by cognitive decline, alteration of synaptic transmission, and neuronal death brought on by accumulation of neurofibrillary tangles in neurons and amyloid beta in the brain. … Continue Reading Study shows that vesicles appear to also contribute to Alzheimer’s disease.
The control of breathing is essential for life. Without an adequate response to increased carbon dioxide levels, people can suffer from breathing disturbances, sickness, and panic; in worst-case scenarios, it … Continue Reading Novel brainstem model show how the brain controls breathing.
Delayed deterioration of neurological function after ischemia stroke is a well-documented clinical problem. However, minimal studies exist pertaining to spinal cord blood flow and blood-spinal cord barrier (BSCB) integrity with … Continue Reading Study maps how a stroke damages the blood-spinal cord barrier.
The hippocampus is a critical structure for encoding of novel experiences. A particularly compelling puzzle is how the hippocampus encodes new information in the presence of interference from past memories. … Continue Reading Neuroimaging shows how the brain switches from past to present memory mode.
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.
Astrocytes are star-shaped cells in the brain that surround brain cells, known as neurons, protecting them from injury and enabling them to function properly. The brain contains billions of cells, … Continue Reading Study breaks new ground on the role and formation of astrocytes in the brain.
When the blood-brain barrier (BBB) is breached the brain becomes vulnerable to infection and injury. Therefore, it’s imperative that the openings in the BBB are resealed quickly. This most frequently … Continue Reading Researchers identify new role for microglia in blood-brain barrier maintainence.
Astrocytes are star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical support of endothelial cells that form the blood–brain barrier, provision of nutrients to … Continue Reading Researchers purify and grow human astrocytes-in-a-dish for the first time ever.
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.
A glioma is a type of tumour that starts in the brain or spine. It is called a glioma because it arises from glial cells. The most common site of … Continue Reading First ever study shows how astrocytes help to spread glioma.
