In research published in the journal Cerebral Cortex, a team of scientists led by the University of Cambridge and the Medical Research Council (MRC) Cognition and Brain Sciences Unit
, Cambridge, studied not only whether volunteers could be trained to follow their heartbeat, but whether it was possible to identify from brain activity how good they were at estimating their performance.
"The origins of these changes could be due to being born with a particular brain dysfunction or it could be due to exposure to adverse environments such as a distressing experience early in life that could have an impact on the way the brain develops," the BBC quoted Dr Andy Calder, from the MRC cognition and brain sciences unit
, who worked on the study, as sdaying.

"If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, assistant director of the Cognition and Brain Sciences unit
at Britain's Medical Research Council, the study's lead author.
Dr Adrian Owen, one of the researchers from the Medical Research Council Cognition and Brain Sciences Unit
in Cambridge, said: "Brain training, or the quest to improve brain function through regular use of computer tests, is a multimillion-pound industry, yet up until now there's been a real lack of robust evidence to show it really works."
experts conducting the tests were Dr Chris Bird, a clinical neuroscientist at the Institute of Cognitive Neuroscience at University College London; Dr Paul Howard-Jones, senior lecturer at the Graduate School of Education, Bristol University, and Dr Adrian Owen, a senior scientist and assistant director at the Medical Research Council's Cognition and Brain Sciences Unit

Now, a team of researchers led by scientists at the University of Cambridge and the MRC Cognition and Brain Sciences Unit
, Cambridge, have used high-density electroencephalographs (EEG) and a branch of mathematics known as 'graph theory' to study networks of activity in the brains of 32 patients diagnosed as vegetative and minimally conscious and compare them to healthy adults.
"This study is the first demonstration of two distinct mechanisms that cause such forgetting: one by shutting down the remembering system, and the other by facilitating the remembering system to occupy awareness with a substitute memory," says lead study author Roland Benoit of the MRC Cognition and Brain Sciences Unit
at the University of Cambridge.
Mental tasks that are closely allied to general intelligence engage specific parts of the brain's frontal lobe, reports a team of neuroscientists led by John Duncan of the Medical Research Council Cognition and Brain Sciences Unit
in Cambridge, England.
"We found a characteristic pattern of brain activity when the jokes used were puns," the Daily Mail quoted Dr Matt Davis, from the MRC Cognition and Brain Sciences Unit
in Cambridge as saying.
