Neuroanatomical Variation in Dogs

Panayiota Siskos ’23 The selective breeding of dogs by humans has led to variation in the brain across different breeds. Selectively breeding dogs for traits and abilities has been a recent occurrence  in evolution, and genetic research shows behavioral variation is heritable. Behavioral specializations depend on neural specializations, and strong selection pressure exhibits that brain differences between dog breeds correlate with differences in behavior. Selection … Continue reading Neuroanatomical Variation in Dogs

Visualizing the Impacts of Age and Disease on the Brain

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 human hippocampus as relevant to advanced age and AD. Thirty-one … Continue reading Visualizing the Impacts of Age and Disease on the Brain
