LANGUAGE AND THE BRAINš§
.
To understand what someone is saying we need to detect their speech and transmit this information to the brain. The brain then has to process these signals to make sense of them.
.
Parts of our brain have to deal with syntax (how the order of words affects meaning) and semantics (what the words actually mean).
.
Memory is also very important as we need to remember what words mean.
.
Then there is the entire vocalisation system which is involved in working out what we want to say and making sure we say it clearly by coordinating muscles to make the right noises.
For more than a century, itās been established that our capacity to use language is usually located in the left hemisphere of the brain, specifically in two areas:
šBrocaās area (associated with speech production and articulation)
šWernickeās area (associated with comprehension).
.
Damage to either of these, caused by a stroke or other injury, can lead to language and speech problems or aphasia, a loss of language.
In the past decade, however, neurologists have discovered itās not that simple: language is not restricted to two areas of the brain or even just to one side, and the brain itself can grow when we learn new languages.
.
More recent findings show that words are associated with different regions of the brain according to their subject or meaning.
