QUESTION 1 We can attribute functions such as decision-making and signaling reward to the basal ganglia. What are some other functions of the three structures of the basal ganglia that you have modeled? The basal ganglia work together to produce the smooth flow of muscles: they coordinate voluntary movement and filter action plans. The caudate nucleus plays an important role in how the brain learns, specifically storing and processing memories. This also uses information from past experiences to influence future actions and decisions, which is especially important in the development of language. The putamen helps coordinate automotive behaviors, such as riding a bike or driving a car. It is involved in the complex feedback loop that prepares and helps the movement of limbs. The globus pallidus is the part of the basal ganglia that, among other things, regulates subconscious movements, and, if damaged, it will cause movement disorders since its regular function will be impaired. QUESTION 2 In the sheep brain we saw that the thalamus acts as a relay point for all sensory processing, and noted the very large size of this structure. Do you think there are differences between the sensory systems of the sheep and the human? For example, do humans and sheep use each sensory system the same amount or are there certain senses that are more prominent in sheep or in humans? How would this manifest anatomically?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
