Humans have evolved an ability to recognize faces, and this ability is so important that there is an area in the brain, the fusiform gyrus, solely dedicated to this task. Brain imaging studies have consistently shown that this region of the temporal lobe becomes active when people look at faces.
A team of Japanese researchers have been working on using neuroimaging techniques to decode the dreams of people while they sleep. The researchers were led by Yukiyasu Kamitani of the ATR Computational Neuroscience Laboratory in Kyoto, Japan and they used functional neuroimaging to scan the brains of patients.
Brain connectivity can predict reading skills, thanks to brain scans and the examination of the growth of long-range connections in the brain. These allow researchers to predict how a child’s reading skills will develop.
A new study indicates that male DNA, left over from pregnancy with a male fetus, can persist in a woman’s brain throughout the rest of her life. Although the exact biological impact of the DNA is yet unclear, the study found that women with more male DNA in their brains were less likely to suffer from Alzheimer’s disease, suggesting that male DNA could help protect mothers from this disease.
Humans will embrace good news and attenuate bad news. People tend to overestimate their odds in a number of different things, while underplaying the risks of cancer, divorce or unemployment. Researchers from the University of College London (UCL) have found a way of removing the optimism bias that humans suffer from by using a magnetic field on a small region of the brain called the left inferior frontal gyrus (IFG).
It’s a biological imperative how organisms respond to threats, and humans are no exception. Humans respond to threats, perceived or real, in an instinctual way, but the exact neuroscience behind these reactions is still somewhat of a mystery.
