Final answer:
Silent reading of an action word like 'kick' would likely activate the motor cortex, as it is involved in planning and executing voluntary movements, even in the absence of physical action. Wernicke's area is also mentioned as a multimodal integrative area associated with language function.
Step-by-step explanation:
When you silently read an action word such as kick, activity would be found in the motor cortex of your brain. This is because the motor cortex is responsible for planning, controlling, and executing voluntary movements, which would be engaged even when imagining or contemplating action words. While areas such as Broca's area may be involved in speech production and Wernicke's area in language comprehension, the act of silently reading action words and potentially visualizing or mentally simulating the action would primarily activate the motor cortex.
Furthermore, when considering multimodal integrative areas, Wernicke's area is an example of such a region in the brain. It is associated with language function, and is located adjacent to the auditory association cortex, just anterior to the visual cortex. It's intricately connected to understanding the content of language, making it a key player in processing the language-based information you read.
