Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Now research published in the journal Cephalalgia, published by SAGE, uses functional magnetic resonance imaging (fMRI) for the first time to suggest a neurological basis for these visual remedies. The new research shows how coloured glasses tuned to each migraine sufferer work...

Researchers at Mount Sinai School of Medicine have published new data on why the aging brain is less resilient and less capable of learning from life experiences. The findings provide further insight into the cognitive decline associated with aging and neurodegenerative diseases like Alzheimer's. The study is published in the May 25 issue of the Journal of Neuroscience. The Mount Sinai team evaluated the prefrontal cortex"”the part of the brain that controls a wide range of cognitive...

The human brain has yet to explain the origin of one its defining features "“ the deep fissures and convolutions that increase its surface area and allow for rational and abstract thoughts. An international collaboration of scientists from the Yale School of Medicine and Turkey may have discovered humanity's beneficiary "“ a tiny variation within a single gene that determines the formation of brain convolutions "“ they report online May 15 in the journal Nature Genetics. A...

Biologists at UC San Diego have discovered that electrical oscillations in the brain, long thought to play a role in organizing cognitive functions such as memory, are critically important for the brain to store the information that allows us to navigate through our physical environment. The scientists report in the April 29 issue of the journal Science that neurons called "grid cells" that create maps of the external environment in one portion of our brain require precisely timed electrical...

The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers led by the Yale School of Medicine and three other universities. The findings, reported April 28 in the American Journal of Human Genetics, are based on a genetic analysis of in one Turkish family and two Pakistani families with offspring born with the most...

By shedding new light on how cells migrate in the developing brain, researchers at Fred Hutchinson Cancer Research Center also may have found a new mechanism by which other types of cells, including cancer cells, travel within the body. The findings by Jonathan Cooper, Ph.D., member and director of the Hutchinson Center's Basic Sciences Division, and Yves Jossin, Ph.D., a research fellow in Cooper's laboratory, published online April 24 in Nature Neuroscience, could lead to a better...

Model of Rett syndrome suggests a deficit in processing cues from the environment Rett syndrome, a neurodevelopmental disorder on the autism spectrum, is marked by relatively normal development in infancy followed by a loss of loss of cognitive, social and language skills starting at 12 to 18 months of age. It is increasingly seen as a disorder of synapses, the connections between neurons that together form brain circuits. What hasn't been clear is why children start out developing normally,...

Scientists are developing a technique to map both the connections and functions of nerve cells in the brain together for the first time, bringing them closer to creating a computer model of the human brain. An emerging area of research in neuroscience known as 'connectomics' has parallels to genomics, which maps our genetic make-up. Connectomics aims to detail the brain's synapses and plot how information travels through the brain. Understanding how perceptions, sensations and thoughts are...

Revelation sheds light on our most ancient sense Researchers seeking to unravel the most ancient yet least understood of the five senses "“ smell "“ have discovered a previously unknown step in how odors are detected and processed by the brain. The four year study, focusing on how mice respond to odors, showed that smells are picked up by the olfactory bulb "“ the first stop on the way to the brain "“ then sent to the olfactory cortex for further analysis. But...

A new study is providing fascinating insight into how projections conveying sensory information in the brain are guided to their appropriate targets in different species. The research, published by Cell Press in the March 24 issue of the journal Neuron, reveals a surprising new evolutionary scenario that may help to explain how subtle changes in the migration of "guidepost" neurons underlie major differences in brain connectivity between mammals and nonmammalian vertebrates. The neocortex...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...

cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
