Neurons to Neighborhoods Focuses on the Teen Brain

Carnegie Mellon University
October 27, 2017

While adolescence is often thought of as a time of turmoil and poor decision-making, it is also an exceptional time of discovery. Adolescence sensation seeking is driven by heightened reactivity to rewards and emotion and can lead to risk-taking, including peaks in car accidents, and experimentation with drugs, unprotected sex and crime. However, this is a necessary time of enhanced learning and exploration that are critical to the transition into adult independence. Read more

New procedure could provide longer lasting Parkinson's disease treatment

Pittsburgh Post-Gazette
May 16, 2017

Taming Parkinson’s disease involves controlling the interaction among brain cells (neurons) in the basal ganglia — the part of the central brain shaped like the @ symbol. In normal function, the neurons chatter among themselves in a way similar to a crowd talking before a concert. The result is steady brain signaling that produces normal motor function. Things go wrong when those neurons quit chattering and become synchronized in their signaling, as though the crowd quit chattering and now is clapping in unison. The result is the notable Parkinson’s disease symptom — shaking hands...In a scientific sense, the CMU biologist [Aryn Gittis] and her team from CMU, the University of Pittsburgh and the CMU/​Pitt Center for the Neural Basis of Cognition, have figured out how to kick the turntable and get the system back to normal function for hours at a time.

Adult Subcortex Processes Numbers With Same Skill as Infants

Dietrich College of Humanities and Social Sciences
March 20, 2017

Despite major brain differences, many species from spiders to humans can recognize and differentiate relative quantities. Adult primates, however, are the only ones with a sophisticated cortical brain system, meaning that the others rely on a subcortex or its evolutionary equivalent.

Carnegie Mellon University scientists wanted to find out whether the adult human subcortex contributes to number processing at all. Published in the Proceedings of the National Academies of Sciences, their study found that the adult subcortex processes numbers at the same level as infants and perhaps other lower-order species, such as guppies and spiders.

Innovation in Brain Imaging

College of Engineering
February 16, 2017

Writers and scientists throughout history have searched for an apt technological analogy for the human brain, often comparing it to a computer. For CMU's Pulkit Grover, this analogy couldn’t be more fitting. Although Grover and his research team spend much of their time exploring how information flows through computer networks (such as coding systems, cyberphysical systems, and low-power wireless systems), they also apply these information theory principles to brain-imaging systems. This cross-disciplinary research approach bridges mathematical theory with clinical applications—striving to improve the treatment of neurological disorders such as epilepsy. Read more

How to Speed Read the Internet

January 29, 2017

Skimming can serve as an exercise in efficiency and prioritization: Is what you’re reading actually worth your time? According to Marcel Just, director of the Center for Cognitive Brain Imaging at Carnegie Mellon, “Sometimes you’re really familiar with something and you can reconstruct the text after skimming. Speed reading isn’t a good method for expanding your knowledge base, but it is a good way to quickly determine what some piece of writing is about and whether it’s worthwhile to go read it in detail or not.” Read more
