You've been appointed as the head neuroscientist for the National Pokemon Research Center! You've been tasked with trying to understand the brain circuits of the many different types of Pokemon in the world. First, you want to examine how the tails of various Pokemon are represented in somatosensory and motor cortex. You start by comparing two Pokemon - Eevee and Mew. They both have tails, but Mew has extremely precise control over their tail while Eevee can only wave its tail back and forth. Additionally, Mew's tail is extremely sensitive and has very good two-point discrimination, while Eevee is not very sensitive to tail touches. Which of the following statements is/are likely to be true? i. The tail area of Mew's primary motor cortex takes up a higher percentage of total primary motor cortex when compared to the tail area in Eevee's motor cortex. ii. The tail area in Mew's primary somatosensory cortex is very over-represented (it takes up more of the cortical area than would be predicted based off of its actual size) iii. Mew's tail skin has a higher density of mechanoreceptors when compared to Eevee's tail. Eevee Mew O a. i and ii only O b. i and ii only Oc. ii and iii only O d. i, ii, and ii O e. None of those statements are true

Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.

Additionally, Mew’s tail is extremely sensitive and has very good two-point discrimination, while Eevee is not very sensitive to tail touches. Which of the following statements is/are likely to be true?
i. The tail area of Mew’s primary motor cortex takes up a higher percentage of total primary motor cortex when compared to the tail area in Eevee’s motor cortex.
ii. The tail area in Mew’s primary somatosensory cortex is very over-represented (it takes up more of the cortical area than would be predicted based off of its actual size)
