Across many groups of animals, species with bigger brains often have better cognitive abilities. But it's been unclear whether overall brain size or the size of specific brain areas is the key. New findings by neurobiologists at the University of Washington suggest that both patterns are important. The researchers found that bigger-bodied social wasps had larger brains and devoted up to three times more of their brain tissue to regions that coordinate social interactions, learning, memory and...

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...

(Ivanhoe Newswire) "“ Brain growth in babies is linked to the amount of time and energy mothers "Ëœinvest', according to this study. The study of 128 mammal species, including humans, shows that brain growth in babies is determined by the duration of pregnancy and how long they suckle. The Durham University research concludes that the longer the pregnancy and breastfeeding period in mammals, the bigger the baby's brain grows. The researchers say the findings reinforce the...

The human brain loses 5 to 10% of its weight between the ages of 20 and 90 years old. While some cells are lost, the brain is equipped with two compensatory mechanisms: plasticity and redundancy. Based on the results of her most recent clinical study published today in the online version of Brain: A Journal of Neurology, Dr. Sylvie Belleville, PhD in neuropsychology, the principal author of this study and Director of Research at the Institut universitaire de g©riatrie de Montr©al...

The Stripe of Gennari develops even in those who are blind from birth and does not degenerate, despite a lack of visual input. This was discovered by Robert Trampel and colleagues from the Max Planck Institute for Human Cognitive and Brain Sciences using magnetic resonance imaging. This bundle of nerve fibers, which is approximately 0.3 mm thick, is not exclusively responsible for optic information. In the blind, it might play a greater role in processing tactile stimuli. This could...

(Ivanhoe Newswire) -- Whether or not you're a fan of Indian, Southeast Asian or Middle Eastern food, stroke researchers at Cedars-Sinai Medical Center say you might become fond of one of their key spices. Curcumin is the principal curcuminoid of the popular Indian spice turmeric, which is a member of the ginger family.  Turmeric is currently being investigated for possible benefits in Alzheimer's disease, cancer, arthritis, and other clinical disorders as well. In the latter half...

Study from Cedars-Sinai Medical Center presented at American Heart Association International Stroke Conference Whether or not you're fond of Indian, Southeast Asian and Middle Eastern food, stroke researchers at Cedars-Sinai Medical Center think you may become a fan of one of their key spices. The scientists created a new molecule from curcumin, a chemical component of the golden-colored spice turmeric, and found in laboratory experiments that it affects mechanisms that protect and help...

Coordinated behavior occurs whether or not neurons are actually connected via synapses The brain"”awake and sleeping"”is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping electric fields, generated by the neural circuits of scores of communicating neurons. The fields were once thought to be an "epiphenomenon, a 'bug' of sorts, occurring during neural...

Frontotemporal dementia is caused by a breakdown of nerve cells in the frontal and temporal region of the brain (fronto-temporal lobe), which leads to, among other symptoms, a change in personality and behavior. The cause of some forms of frontotemporal dementia is a genetically determined reduction of a hormone-like growth factor, progranulin. Scientists around Dr. Anja Capell and Prof. Christian Haass have now shown that various drugs that are already on the market to treat malaria, angina...
