What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology. – What is neurology? – Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them. – Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.
Genetics of human face begin to reveal underlying profile
Using 3-D facial images with over 7,000 data points, researchers have identified changes in the DNA sequence of European individuals that contribute to variation in facial features. These findings help us better understand human variation and facial birth defects.

Genetics of human face begin to reveal underlying profile

UNIVERSITY PARK, Pa. The genetics behind the shape of the human face are difficult to decipher, but now an international team of researchers has connected specific genetic signals with specific areas of the face. They not only can see the signals of normal facial features in the genome, but also hope their work can shed light on craniofacial malformations such as cleft lip and palate.
New research connects specific genetic signals with specific areas of the human face.

“The face tells the outside world about your identity, who you are related to, where your ancestors come from, and even your health,” says Julie White, graduate student in anthropology at Penn State. “But we only know a fraction of how faces are formed. The facial structure comes together in early development, and if it doesn’t go right, you can get a cleft palate or other problem, but we don’t fully know what controls those processes.”
