Which area of the brain is involved in abstract thought and understanding written language?

The parietotemporal association cortex plays a crucial role in higher cognitive functions, including abstract thought and the comprehension of written language. Located in the parietal and temporal lobes of the brain, this area integrates information from multiple sensory modalities and is essential for processing complex language structures. It is involved in reading and understanding written text by enabling the connection of symbols (letters and words) to their meanings.

In contrast, the motor cortex primarily manages voluntary muscle movements and does not directly contribute to abstract thinking or language comprehension. The primary auditory cortex focuses on processing sound information, including spoken language, but it does not facilitate understanding written language. The cerebellar cortex is mainly associated with motor control and coordination, playing a limited role in cognitive processes compared to the parietotemporal association cortex.
