Most of us will be familiar with the experience of silently talking to ourselves in our head. If this is true, does inner speech use the same mechanisms in the brain as when we speak out loud? We have known for about a century that inner speech is accompanied by tiny muscular movements in the larynx, detectable by a technique known as electromyography. So the evidence that inner speech and speaking out loud share similar brain mechanisms seems pretty convincing.
One worry, though, is whether the inner speech we get people to do in experiments is the same as our everyday experience of inner speech. Typically, studies have required participants to repeat sentences to themselves in their heads, or, sometimes, count the syllables in words presented on a computer screen.
One reason is that understanding typical inner experience may be the key to understanding more unusual inner experiences. Neuroscientists have found some evidence in favour of this theory. When they scanned the brains of people who reported hearing voices, they discovered that many of the same areas of the brain are active during both auditory hallucinations and inner speech.
But if we really want to know what the difference between what happens in the brain Ure Where U Wanna B - Inner Voice* - Post-Millenium Outer Space inner speech and voice hearing — and how inner speech might become hearing voices — then first we need to understand what our internal talk is usually like.
A recent study by researchers in Finland attempted to address flaws in previous brain-imaging studies of inner speech. Using functional magnetic resonance imaging fMRIthey studied the difference between activity in the brain when participants experienced an auditory verbal hallucination, and when they deliberately imagined hearing the same voice. In this way, they controlled for aspects of the experience such as the sound and the content of the voice.
They found the main difference between the two conditions was the level of activation in a cortical region known as the supplementary motor area SMAwhich contributes to the control of movement.
Of course, none Ure Where U Wanna B - Inner Voice* - Post-Millenium Outer Space this is to say that understanding what happens in the brain is the only, or the most important, aspect of research into hearing voices.
But to do any of this, we first need to know what typical inner speech is like, and the underlying neuroscience is part of that understanding.
