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.
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.
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.
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.
During brain development, the formation of neuronal synapses at the right time, the right place, and the right strength are crucial to the ongoing function of the brain throughout life. … Continue Reading Astrocytes regulate the formation of synapses in neurodevelopment.
The brain consists of two major types of cells, namely neurons and glial cells, with the immune-based glial cells providing support and protection for neurons in the central and peripheral … Continue Reading Study identifies previously unknown role of microglia in neurodevelopment.
A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals. This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.
The rapid rise in obesity and associated spread of type 2 diabetes represent an enormous challenge for society, with no efficient and safe medicines to prevent or stop this development … Continue Reading Astrocytes shown to control sugar in the brain, as well as neurons.
Twenty-years ago there was a big step forward in the understanding of obesity when researchers discovered that a person’s appetite is controlled by a key molecule called leptin. Leptin is … Continue Reading Glia brain cells implicated in appetite control.
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.
Scientists have long suspected that neuroinflammation caused by a reactive immune system could be tripping off the neurodegeneration seen in certain dementias, multiple sclerosis, and other deadly diseases of the … Continue Reading Immune response in the human brain accurately measured for the first time ever.
The mission of neural stem cells located in the hippocampus, one of the main regions of the brain, is to generate new neurons during the adult life of mammals, including … Continue Reading Researchers validate microglia role in reducing neurogenesis due to epileptic seizures.
Hot on the heels of discovering a protective form of immune response to spinal cord injury, researchers at the University of Virginia School of Medicine have pinpointed the biological trigger … Continue Reading Researchers identify trigger for protective immune response to spinal cord injuries.
A new international collaboration led by The University of Montana and Secretaria de la Defensa Naciona heightens concerns over the detrimental impact of the apolipoprotein E (APOE) ε4 allele, the … Continue Reading Decreases in short-term memory and IQ in urban children with ‘Alzheimer’s gene’.
