Humans Remain Behaviorally Responsive to External Auditory Stimuli During Deep Sleep

Author: Vignesh Subramanian, Class of 2024 It has long been assumed that sleep is a stable state of unconsciousness in which an individual cannot perceive and respond to most external stimuli. However, recent studies have indicated that humans can process information, discriminate between basic sensations, and carry out limited executive functions, such as answering yes–no questions, while still asleep. Some oneirological studies have focused on … Continue reading Humans Remain Behaviorally Responsive to External Auditory Stimuli During Deep Sleep

Cranial Windows Enable Transcranial Ultrasound Imaging of CSF Disorders

Vignesh Subramanian ’24 Figure 1: A CT scan of a human brain with hydrocephalus, made visible by the enlarged ventricles. Hydrocephalus is a neurological disorder characterized by the abnormal accumulation of cerebrospinal fluid (CSF), the plasma fluid in which the brain is suspended and cushioned, in cavities of the brain known as ventricles. CSF disorders like hydrocephalus develop when CSF is either excessively produced or … Continue reading Cranial Windows Enable Transcranial Ultrasound Imaging of CSF Disorders

Nicotine exposure discovered to block aromatase activity in healthy women

Jessica George ’24 Figure 1 Nicotine use disorder has a profound impact on hormones, yet sex differences are poorly understood. Maintaining a harmonious sex-hormone balance is essential for the optimal functioning of the body, as it regulates a wide range of physiological processes. Aromatase serves as the critical enzyme responsible for the conversion of androgens into estrogens, a process fundamental to functions associated with emotional … Continue reading Nicotine exposure discovered to block aromatase activity in healthy women

Understanding the Neurobiology of Love and Deception

Julia Chivu ’23 Figure 1  Couple holding hands walking towards a multi-colored sunset Recent scientific research has been increasingly focused on better understanding the complex relationship between deception and love. The study of deception within relationships and across genders is essential for interpreting the correlation between human behavior, neural mechanisms, and trust. A research team from Zhejiang Normal University investigated the neurological mechanisms of deception … Continue reading Understanding the Neurobiology of Love and Deception

Radiation-Induced Cognitive Decline Impairs Hippocampal Neurogenesis

Vignesh Subramanian ’24 Figure 1: A radiograph captured by X-ray, which produces ionizing radiation, a form of radiation that poses risks of damage to internal tissue. Ionizing radiation is any radiation traveling in the form of electromagnetic waves or particles with enough energy to knock electrons out of the orbit of atoms. While therapies such as radiotherapy for cancer are intended to emit ionizing radiation … Continue reading Radiation-Induced Cognitive Decline Impairs Hippocampal Neurogenesis

Microdosing Psychedelics

Shahzadi Adeena ’25 In recent years, there has been a growing interest in microdosing psychedelic drugs as a potential tool for enhancing cognitive abilities and improving overall wellbeing. Vince Polito and Richard J. Stevenson of Macquarie University investigated the effects of microdosing psychedelics on psychological variables such as mood, attention, wellbeing, mindfulness, mystical experiences, personality, absorption, creativity, and sense of agency. The researchers hypothesized that … Continue reading Microdosing Psychedelics

Return of Consciousness After Traumatic Brain Injury

Shahzadi Adeena ’25 Understanding the fundamental mechanisms of consciousness, particularly following traumatic brain injury (TBI), is nuanced and challenging. Thalamic function plays a critical role in facilitating consciousness; injury to thalamus-frontal circuitry can impair consciousness. Sima Mofakham and Charles Millek of Stony Brook University hypothesized that thalamocortical projections to the frontoparietal network facilitate the complex dynamics needed for consciousness, and that injury to these connections … Continue reading Return of Consciousness After Traumatic Brain Injury

21 Million Year Old Fossil Reveals Hominid Environment and Diet

Julia Chivu ’23 The Motroto site in Uganda has recently provided new insights on the evolution of the locomotor versatility, diet, and environment of early hominids. The site is estimated to be twenty-one million years old. Associate professor in the Department of Anthropology at Stony Brook University, Dr. James Rossi, is part of a large research team that has recently examined the fossil remains of … Continue reading 21 Million Year Old Fossil Reveals Hominid Environment and Diet

Differentiating Between Speech and Song Across Cultures

Julia Chivu ’23 Given that speech and song are produced by the same vocal tract, there is an ongoing debate as to whether or not speech and song can be distinguished by their acoustical features across different societies. It can be difficult to determine where speech ends and songs begin within a culture. This concept is especially challenging to research since there is no reliable … Continue reading Differentiating Between Speech and Song Across Cultures

Bupropion as a Possible Treatment for COVID-19-Related Brain Fog

Jessica George ’24 The COVID-19 pandemic has affected millions of people worldwide, and many have reported persistent symptoms even after recovery from the initial infection. One of the most common long-term symptoms reported is “brain fog,” a condition characterized by cognitive impairments such as memory loss, difficulty concentrating, and mental fatigue. A recent case series published by Dr. Samuel Reinfeld from the Stony Brook University … Continue reading Bupropion as a Possible Treatment for COVID-19-Related Brain Fog

Transgender and Gender Diverse Individuals at Greater Risk For Suicidal Ideation

Jessica George ’24 Suicide has been a long standing issue in the United States, with several socio-demographic and economic factors affecting an individual’s susceptibility to suicide risk. Transgender and gender diverse individuals (TGD) are at especially high risk. Given the high rates of suicide among TGD, as well as the lack of research in this area, it is important to address this gap. Dr. Kirakosian … Continue reading Transgender and Gender Diverse Individuals at Greater Risk For Suicidal Ideation

Growth of Artificial Brain Tumors Using Three Dimensional Cell Culture

Julia Chivu ’23 Three dimensional culture systems and patient derived cells successfully allow for tumoroid development. Tumoroids are structures that grow and appear morphologically similar to naturally growing tumors in a patient. Tumoroids show promise for testing new drugs and cancer treatments. For instance, glioblastoma is a form of brain cancer that is aggressive, fast growing, and deadly. In particular, the mesenchymal subtype of this … Continue reading Growth of Artificial Brain Tumors Using Three Dimensional Cell Culture
