A polymodal brain region is an association are whose neurons have
receptive fields defined by MORE THAN ONE sensory modality (e.g., vision,
somatosensations or vision/hearing, etc.) Discuss the adaptive significance of the
expansion of the polymodal regions PG and STS in humans compared to other
primates.

Polymodal brain regions are the areas in the right brain with support the human sense. These are the part of the cerebral cortex that receives the input from a different type of area including sensory information and motor areas.
The polymodal brain region in association with the neurons that involve sensory immortality including vision and hearing involves brain activation. These are the main sensory organ in which the external portion of the eye and ear are specialized and they possess high threshold mechanoreceptors are observed in the form of poly model receptors. This is also involved in the interpretation of touch and pain in the body. The occipital lobe is the back part of the brain which is involved in the division. Neural recognition can be expressed in the form of complex activity and handling of stimuli.
The adaptive significance of the expansion of the volume model region of PG and STS in the human being as compared to primate are the signals which are responsible for direct projection to the nucleus. In the human primate, there is prefrontal control of adaptive significance. Polymodal processing also indicates the posterior parietal area that is located in the activation of the brain area which assists in the areas of speech.

Genome-wide association studies have identified many genomic loci at which the presence of one or more SNPs is associated with altered risk of a particular disease. Almost all of these SNPs have a very small influence on risk of the corresponding disease, typically with effect sizes of less than 1.5. What does it mean to have an effect size of less than 1.5?

Obese individuals generally have more (protein/pyruvate/lipoprotein hydrase/lipoprotein lipase) activity in their fat cells than normal weight individuals. This is an enzyme responsible for removing triglycerides from the blood stream and placing them in fat storage. 4.
