Brain lateralization means that each hemisphere has its own functions. Give an example of both a left hemisphere and a right hemisphere function. Then explain how the two hemispheres communicate with one another. (Do not use the examples from the book. Use real-life examples).Please respond.

the corpus callosum sends info between the left and right hemispheres. the left hemisphere is involved with speech and logic (controls right side of the body) while the right is focused on patterns and facial recognition (controls left the side of the body) when doing an imcomplete x/y chart problem in math, the right hemisphere will recognize the pattern between the filled in numbers, and the left side will use logical reasoning to fill in the chart with correct numbers to fulfill the pattern

the dual-processing model refers to which of the following ideas?

the right and left hemispheres of the brain both process incoming messages

why do researchers study the brains of nonhuman animals?

the same principles govern neural functioning in all species
