21.   The researchers found no evidence to link heavy alcohol intake with any form of cognitive decline or with atrophy of the brain regions involved in cognitive functions.

22.   These clumps of protein accumulate outside diseased neurons in the parts of the brain that control higher cognitive functions such as judgment and memory.

23.   They had blood-pressure readings taken nine years apart and were given brief cognitive function tests every three years to check for any mental decline.

24.   They then used a technique called magnetic resonance spectroscopy to measure levels of NAA and choline in a brain region involved in a wide variety of cognitive functions.

25.   Those blood vessels control brain temperature much in the same way a radiator cools a car engine, allowing for higher cognitive functions.

26.   Wilson is well aware that people do not always warm to the idea of having their higher cognitive functions explained in terms of genetic programming.

27.   Patients fill out a questionnaire, which is then used to measure the cognitive function of the brain.

28.   Cutting-edge brain tests are revealing cognitive function.

29.   He said it could be that social engagement uses the cognitive functions of the brain, keeping it active.

30.   In schizophrenics, cognitive functions in the higher part of the brain are impaired, leading them to have trouble with memory, concentration and reason.
