Brain Interlocks Time and Numbers, Like a Clock

Our minds are like clocks when it comes to time and numbers, according to a new study.

In two experiments, scientists found that people associate small numbers with short time intervals and large numbers with longer intervals-suggesting that these two systems are linked in the brain.

Vitamin E can Protect Brain After Stroke
Alpha-tocotrienol - a natural form of vitamin E if used for 10 weeks as preventive supplementation, can protect brain damage post stroke, finds study.

It's clear that time and numbers are related in daily life, says Denise Wu of National Central University of Taiwan, who co-wrote the new study with Acer Chang, Ovid Tzeng, and Daisy Hung.

"We are really excited about this because this means the influence of the digit is so automatic and so immediate," she says.

The results suggest that the brain somehow processes time and the size of numbers together-possibly even with the same neurons.

Study Says The Brain Continues to Remember Even After Loss of Cognitive Skills
The damaged brain continues to process information even when the patient has lost his cognitive skills, says a new study.

So, maybe instead of having different parts of the brain devoted to different kinds of measurement, there's some part of the brain that is generally responsible for thinking about magnitude.

"It shows that it's not like, mentally, we have a clock and it is immune to all the other information," Wu says.

Scientists Fear Risk Of Psychiatric Disorders In Premature Babies With Abnormal Brain Ultrasounds
Infants born prematurely are at risk for injuries to the white and gray matter of the brain that affect cortical development and neural connectivity.

Instead, your concept of time is responding to other things going on in the brain. In this case, it's numbers, but it might also be influenced by emotion.

The study will be published in the journal Psychological Science.

Vitamin C Vital For Brain
Vitamin C could prove vital for the brain to function properly, scientists believe. The new hypothesis comes in the wake of the discovery that nerve cells in the eye require the vitamin.
