Threatening cues have a larger effect on perception than neutral cues

Panayiota Siskos ’23 The theory of predictive coding states that the brain continuously creates a mental model of the surrounding environment using prior knowledge from memory. This mental model is then used to predict sensory input, such as anticipating a smell, a sound, or a touch.  A group of researchers from Stony Brook University and Columbia University studied the effect of threatening cues on sensory … Continue reading Threatening cues have a larger effect on perception than neutral cues

Examining the Benefits of Unique Coloration for Male Trinidad Guppies

Fatin Chowdhury ’20 The predisposition of organisms in seeking certain phenotypic traits in mates is an oft-observed aspect of the natural world, with sexual selection being a well-studied phenomenon. However, unique coloration specifically often seems to be more linked to lessened survivability (due to an inability to camouflage in environments), or phenomena such as aposematism, where unique colors serve as a warning for predators. In … Continue reading Examining the Benefits of Unique Coloration for Male Trinidad Guppies

How Do We Recognize Dog Emotions?

Ayesha Azeem ‘23 We humans are very complex creatures. When we spend a lot of time in close association with a species, we tend to treat them as if they are humans as well, and we can decipher their emotions clearly. With the expression of emotions, we can communicate our motivations, responses and needs to others. Recognizing animals’ emotions can be beneficial, as it may … Continue reading How Do We Recognize Dog Emotions?

Increased Levels of Gray Matter in the Brain May Lead to Psychopathic Qualities

Joyce Chen ’23 Psychopathy is a genetic mutation in the brain that causes individuals to have egotistical tendencies. Such tendencies can lead to unwarranted actions such as crime or even murder, as psychopaths do not keep the wellbeing of others in mind. However, some psychopaths are capable of keeping their dark thoughts hidden very well, thereby having seemingly socially acceptable behavior. Recently, researchers from the … Continue reading Increased Levels of Gray Matter in the Brain May Lead to Psychopathic Qualities

Relationship Between Academic Environment and the Mental Health of Students

Raymond Cheung ‘22 Researchers at the University of Munich and other universities analyzed the effect of a high-achieving environment on the mental health of students. Their work is vital because it provides insight into how a high-performing environment can harm the academic development and mental wellbeing of students. In the study, the researchers analyzed the responses of over 7,700 German school students with regards to … Continue reading Relationship Between Academic Environment and the Mental Health of Students

By Snigdha Kanadibhotla ‘21 Characterized by uncontrollable and spastic movements, Huntington’s Disease (HD) is a fatal neurodegenerative disorder that is estimated to affect about 1 in 10,000 people in the United States (1). HD has pervasive effects that damage neurons in brain regions associated with mobility, emotion, and intellectual capacity leading to symptoms such as depression, anxiety, and difficulty learning. Despite its complex and varied … Continue reading A Novel Approach to Treating Psychopathy Associated with Huntington’s Disease.

Figure 1. Enzyme that plays a role in memory loss can be inhibited to treat Alzheimer’s disease

Disrupting Enzyme To Tackle Alzheimer’s Disease

By Rideeta Raquib ’19 From histone modifications to DNA alterations, epigenetic processes play a major role in various physiological systems. Histones are proteins in eukaryotic cells that package DNA strands into nucleosomes. Gene regulation processes include histone acetylation, whereby an acetyl group is transferred from one molecule to another. This eventually removes the positive charge on the histones, giving nucleosomes a relaxed structure and allowing … Continue reading Disrupting Enzyme To Tackle Alzheimer’s Disease

A New Model for Group Decision-Making

By Anna Tarasova ’19 Making a decision in a group requires integrating individual and group beliefs. It has been previously demonstrated that one is more likely to assign greater credibility to the beliefs of a larger group than to those of a smaller group. Prior researchers have also theorized that the adoption of group beliefs by individuals is driven by a desire to mitigate potential … Continue reading A New Model for Group Decision-Making

Figure 1: Defensiveness is a common symptom of ASD, manifesting in anxiety, social deficits, or other behavioral and psychological symptoms.

A Potential Mechanism Explaining Tactile Defensiveness in Autism

By Anna Tarasova ’19 Hypersensitivity to sensory stimuli is frequently an aspect of autism spectrum disorders (ASD), and can lead to defensiveness against touch and other sensory stimuli. This can contribute to hyperactivity and lead to inattention, learning difficulties, sleep disturbances, anxiety, and many other symptoms of autism. Although the mechanism of this phenomenon has long been unknown, Dr. Cynthia He and her colleagues at … Continue reading A Potential Mechanism Explaining Tactile Defensiveness in Autism
