525-million-year-old fossil contradicts textbook theory of brain evolution
Updated : 3 years, 3 months ago IST
According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous syste

Study gives more insight into vagus nerve's link to brain
Updated : 3 years, 3 months ago IST
Researchers at the University of Colorado Anschutz Medical Campus have shown a direct link between vagus nerve stimulation and its connection to the learning centres of the brain. The discovery may lead to treatments that will improve cognitive retention in both healthy and injured nervous s

Research: Growing motor neurons guided by 'love-hate relationship' with bl
Updated : 3 years, 4 months ago IST
When neurons involved in movement called motor neurons form, they must build connections that reach from the brain, brainstem, or spinal cord all the way to the head, arms, or the tips of the toes. How neurons navigate these systems and "decide" where and how to grow has largely been a myste

Exposing the evolutionary weak spots of the human genome: Research
Updated : 3 years, 5 months ago IST
Washington [US], September 27 (ANI): Mutations can drastically help or hurt the odds of an organism surviving and reproducing. Researchers have created a computer program called ExtRaINSIGHT that tracks the history of harmful mutations throughout human evolution. They've discovered several r

Updated : 3 years, 5 months ago IST
Washington [US], September 21 (ANI): Currently, there are no effective treatments for spinal cord injury; physical rehabilitation can help patients regain some mobility, but the outcomes are severely limited in severe cases due to the failure of spinal neurons to regenerate naturally after i

Infant antibiotic use may negatively affect adult gut health
Updated : 3 years, 6 months ago IST
London [UK], September 9 (ANI): Antibiotics are frequently administered to preterm and low birth weight infants in order to prevent infections, not simply treat them as they have a higher risk of developing them. A recent study discovered that neonatal mice exposed to antibiotics early in li

Study: Untapped stem cell potential may help heal damaged spinal cord
Updated : 3 years, 6 months ago IST
Washington [US], August 23 (ANI): Scientists have identified a group of latent stem cells that respond to injury in the central nervous system of mice. If a similar type of cell exists in humans, they could offer a new therapeutic approach to treat brain and spinal cord injuries.

Study: Genetic variation within and between species to affect animal menta
Updated : 3 years, 7 months ago IST
Tokyo [Japan], August 5 (ANI): Our cognitive and emotional processes depend heavily on monoamine neurotransmitters like serotonin and dopamine. Their evolutionary ancestors were metazoans, and while related genes' functions have remained mostly unchanged over time, genetic variation within a

Study discovers brain evolution of lungfishes
Updated : 3 years, 7 months ago IST
Adelaide [Australia], July 20 (ANI): With the help of research on ancient lungfish fossils, which filled in a gap in the history of land-living, four-legged creatures on earth, the evolution of the brain and nervous system in animals has been rewinded by more than 400 million years.

Updated : 3 years, 8 months ago IST
Washington [US], July 13 (ANI): According to a recent study, a type of central nervous system cell, Microglia is primarily responsible for neuronal death in Leigh Syndrome and the neurological symptoms related to this mitochondrial disease. This research was measured by using a mouse model o
