By Mariam Malik ‘22 The cerebellum, a five-centimeter wide part of the hindbrain, was initially thought of as having one major function: coordinating motor functions and balance. But new research on mice from the Albert Einstein College of Medicine in New York City shows that the remarkable cerebellar cortex may play a part in our…
By Natalie Lo ‘21 Alzheimer’s Disease (AD) is characterized by the formation of β-amyloid plaques Aβ, microglial activation, and inflammation in the brain. Microglia are immune cells found in the central nervous system (CNS). In AD, the blood-brain barrier is disrupted, which leads to bleeding, vascular damage, and an increase in blood proteins. Currently, there…
By Natalie Lo ‘21 Alzheimer’s Disease (AD) is the most prevalent type of dementia with links to memory impairment and behavioral issues in those diagnosed. Although the cause of AD is unknown, molecular characteristics of the disease include the growth of β-amyloid oligomers, which form plaques that result in brain atrophy. Previous studies have shown…
Caleb Sooknanan ‘20 Aging is often associated with increased neurological problems among humans, and more research is needed to understand how lymphatic vessels connecting the brain and the immune system affect conditions such as Alzheimer’s disease. Doctor Jonathan Kipnis and researchers from the University of Virginia enhanced the lymphatic vessels of aging mice and significantly…
Rachel Kogan ’19 “Neurons that fire together, wire together.” This age old phrase serves as the foundation for neuroscience, commenting not only on neuron synchronicity, but also proposing a biological scaffold for behavior and thought. The greater the number of oscillating electrical impulses, or brain waves, fired by a group of neurons, the stronger the…
By Marcia-Ruth Ndege ‘21 Human pluripotent stem cells can differentiate into nearly any cell in the human body. Recently, geneticist Abed AlFatah Mansour and other scientists from the Salk Institute for Biological Studies used them to build human brains in mice. The differentiation of human pluripotent stem cells gave rise to small brain-like structures known…
By Fatin Chowdhury ‘19 Alzheimer’s disease (AD), a common neurodegenerative disorder, has previously been found to increase atrophy rate of the hippocampus, an area of the brain associated with learning and memory. In relation to this issue, Dr. Daniel H. Adler and researchers from the University of Pennsylvania recently examined specific structural details of the…
