By Neha Madugala, Cognitive Science, ‘21 Author’s Note: Previous studies in neuroscience have suggested that our expectations and prior experiences impact how we perceive reality and current tasks. This idea is embedded in Bayesian integration, also referred to as multisensory integration, which essentially studies how the brain combines information obtained from sensory neurons to affect perception and create a distinct outlook on an organism’s surroundings. It defines how we view and think about our environment. This topic was particularly interesting to me because expectations can serve to aid our further understanding of incoming information, but can also inhibit our understanding if the new information contradicts our predictions. Scientists classify expectations as essentially creating a placebo effect. The idea is that […]
By Reshma Kolala, Biochemistry & Molecular Biology ‘22 Author’s Note: While browsing recent findings in Neuroscience, I came across research investigating the possible conversion of glia to neurons. Although the conventional idea that neurons are irreplaceable has been overturned in multiple research studies, I was immediately intrigued by the possibility for neighboring glia to be the source of neural regeneration. The implications of this research could completely transform how treatment is approached in the neuroscience field of medicine.
By Timur Katsnelson, Neurobiology, Physiology, and Behavior, ‘19 Author’s Note: Like everyone else, I love music- especially the works of my favorite artists. There is nothing better than listening or jamming out to your favorite song. The human love for music is a powerful binding force, but why do we even like it? What are the underlying physiological responses of our enjoyment? I wanted to explore the functions of our brain as they relate to enjoying music, and found some interesting results about what scientists have uncovered thus far. One of the most distinguishing characteristics of the human brain is the ability to interpret and feel emotions regarding complex environmental stimuli such as visual arts and music. Even more […]
By Neha Madugala, Cognitive Science, ‘22 Author’s Note: While working on a different paper, I became interested in treatment and therapy for drug addiction. Addiction continues to increase, yet there seem to be limited viable options to actually overcome this problem. One of the main issues in the recovery process is relapses. I found this study interesting and promising for drug therapy because it directly targets relapses, an important step in preventing and treating drug addiction more effectively.
By Raida Aldosari, Nutrition Science (Biology option) ’18 Author’s Note: I wrote this literature review as part of my UWP 104F class with Dr. Lisa Sperber. The assignment was to choose a clinically-relevant topic, review the existing body of literature on this topic, and choose a specific area to write on. My topic of interest was about the relationship between gut microbiome and the brain. I became interested in this topic after reading an article about the differences between the microbial composition of individuals with depression. By the end of the quarter, my research question evolved from “how does our diet affect our brain or mood?” to “how does modulation of gut microbiome affect depression pathophysiology?” I enjoyed the flexibility of the […]
By Neha Madugala, Cognitive Science, ‘22 Author’s Note While browsing recent scientific achievements and breaking news in the scientific community, I came across an article declaring that the 125-year-old neuroscience mystery surrounding perineuronal nets (PNNs) is finally resolved. PNNs have stumped neuroscientists for decades, yet their importance is undeniable. To understand the extent of this discovery, I read more about PNNs and found that they have a key connection to Angelman syndrome, which causes severe epileptic seizures in children. The new findings from the Philpot Lab identifying the purpose of PNNs draw a connection between PNNs and seizures, and this information can lead to improved medications and therapeutic treatment methods.
By Timur Katsnelson, Neurobiology, Physiology, and Behavior, ‘19 Author’s Note This topic was brought up during our discussion on the development of the nervous system in my neurobiology foundations class. I found it to be interesting because of its significance in the earliest stages of our lives. Further research into scientific literature discussing the role of pruning in neurodevelopment led me to learn more about its mechanism, distinctions from other forms of axon degrading, and its use in adult organisms.
