Speech Zone Sensory

The sensory speech area is one of the important areas of the cerebral cortex, which is responsible for processing and analyzing sounds. It is located in the left hemisphere of the brain and occupies most of the temporal lobe.

The sensory speech zone was discovered by the German neurologist Carl Wernicke in 1874. This scientist discovered a functional connection between speaking and verbal hearing. However, only almost a century later, it became clear that speech centers are already formed during the embryonic development of the fetus. Thanks to numerous studies, it was possible to find out that the speech zone is formed in the first months of intrauterine development, and its final formation occurs after birth.

The sensory speech areas have a number of unique functions that help us perceive speech and understand human speech. First of all, this concerns the acoustic component of speech, that is, the sound stream perceived by ear. But in addition, with the help of this area, the brain processes other types of information that are supplied through reproduction

The speech zone of the sensory cortex is a section of the sensory (primary) cerebral cortex located in front of Broca’s center, i.e. in the region of the third frontal gyrus. Its name includes the first part of the term designating this area - Wernicke, or the zone of the second signal system. Therefore, it is sometimes also called Wernicke's center. However, it was named not by name, but by the results of N.A.’s research.
