To speak sensibly, you must think of words to convey an idea or message, formulate them into a sentence according to grammatical rules and then use your lungs, vocal cords and mouth to create sounds. Complementary to this is expressive language, which is the ability to produce language. This enables our receptive language abilities, which means the ability to understand language. These regions work together as a network to process words and word sequences to determine context and meaning. These include the angular gyrus in the parietal lobe, Wernicke’s area (comprising mainly the top rear portion of the temporal lobe), insular cortex, basal ganglia and cerebellum. If you listen to someone else reading, then you use the auditory cortex not far from your ears.Ī system of regions towards the back and middle of your brain help you interpret the text. If you are reading in Braille, you use the sensory cortex towards the top of the brain. This complex process involves many brain regions.ĭetecting text usually involves the optic nerve and other nerve bundles delivering signals from the eyes to the visual cortex at the back of the brain.
When you read something, you first need to detect the words and then to interpret them by determining context and meaning.
Xpressive imaging series#
For now, though, our Brain Control series explores what we do know about the brain’s command of six central functions: language, mood, memory, vision, personality and motor skills – and what happens when things go wrong.
The brain is key to our existence, but there’s a long way to go before neuroscience can truly capture its staggering capacity.
