 Brain's Face Recognition Ability Diminishes With Age

A British study suggests that our ability to identify and recall a face, when it is shown for only a fraction of a second, reduces as we age.

Lead researcher Guillaume Rousselet, from the University of Glasgow, came to this conclusion after analysing electric activity from the brains of young and old people as they watched pictures of faces with cloud-like noise.

He said: "Very few studies have attempted to measure the effect of ageing on the time-course of visual processing in response to complex stimuli like faces. We found that, as well as a general reduction in speed in the elderly, one particular component of the response to a face, the N170, is less sensitive to faces in the elderly."

The N170 occurs 170 milliseconds after a stimulus is presented.

The researchers revealed that it was more closely associated with the appearance of a face among the young subjects.

However, in older subjects, the researcher said that it occurred also in response to noise, perhaps implying reduced ability to differentiate faces from noise.

Revealing the findings of the study, Rousselet said: "Our data support the common belief that as we get older we get slower. Beyond this general conclusion, our research provides new tools to quantify by how much the brain slows down in the particular context of face perception. Now, we need to identify the reasons for the speed reduction and for the heterogeneity of the effects - indeed, why the brains of some older subjects seem to tick as fast as the brains of some young subjects is, at this point, a complete mystery."

The study has been published in the journal BMC Neuroscience.
