Celestial Maps: A Newly Discovered Method of Navigation in Bogong Moths

Author: Sean Krivitsky, Class of 2026 Figure 1. Clustering formation of bogong moths following migration Many different species of animals have been observed to perform migratory travels for a variety of reasons, including searching for food, being influenced by changes in climate, or finding a safe breeding ground. These animals do so using unique methods of navigation–some may learn from previous generations’ migration patterns. In … Continue reading Celestial Maps: A Newly Discovered Method of Navigation in Bogong Moths

AD-Linked Proteins Linked to Cognitive Impairment Following 9/11 WTC Exposure

Vignesh Subramanian ’24 Figure 1: The South Pool of the 9/11 Memorial in New York, New York Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by a progressive loss of memory and cognitive thinking skills that typically worsens with age, and is the leading cause of dementia. Key hallmarks of the disease include buildups of two particular proteins – beta-amyloid peptide and phosphorylated tau – … Continue reading AD-Linked Proteins Linked to Cognitive Impairment Following 9/11 WTC Exposure

Chronic Pain Signaling Predicted by Orbitofrontal Cortex Signatures

Vignesh Subramanian ’24 Figure 1: A sagittal MRI view of the human orbitofrontal cortex. Chronic pain syndromes typically entail persistent pain lasting at least three months, marked by the long-term rewiring of neural circuitry that triggers unprompted pain signals. Measuring chronic pain has long proven challenging due to its entanglement with a wide array of overlapping neural circuits and the subjectivity with which it is … Continue reading Chronic Pain Signaling Predicted by Orbitofrontal Cortex Signatures

PD-Modeling Midbrain Dopamine Loss Diminishes Thalamocortical Signaling

Vignesh Subramanian ’24 Figure 1: The substantia nigra (SN) nucleus in the midbrain. Parkinson’s disease (PD) is an age-related, neurodegenerative movement disorder that causes a progressive loss of motor control. The disease is characterized by a loss of dopaminergic (DA) neurons in the substantia nigra (SN), a midbrain nucleus that modulates movement and reward functions. The SN is one of five subcortical nuclei that make … Continue reading PD-Modeling Midbrain Dopamine Loss Diminishes Thalamocortical Signaling

Maternal Empathetic Cortical Responses Synchronize with Neonatal Pain Perception

Vignesh Subramanian ‘ 24 Figure 1: The heel prick of an infant’s foot, which often induces momentary pain for the infant. The early psychophysical development of newborns relies heavily on having strong emotional bonds with caregivers. Compared to other animals, human infants are born highly dependent on their parents, undergoing a prolonged period of extensive neural organization and brain development that requires greater parental sensitivity … Continue reading Maternal Empathetic Cortical Responses Synchronize with Neonatal Pain Perception

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

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
