Carnegie Mellon study identifies where thoughts of familiar objects occur inside the human brain

A team of Carnegie Mellon University computer scientists and cognitive neuroscientists, combining methods of machine learning and brain imaging, have found a way to identify where people's thoughts and perceptions of familiar objects originate in the brain by identifying the patterns of brain activity associated with the objects.

Study examines computed tomographic pulmonary angiography for diagnosing blood clots in the lung

New research indicates that a diagnostic strategy using computed tomographic pulmonary angiography (CTPA) may be a safe alternative to conventional lungs scans (known as ventilation-perfusion scans) for excluding the diagnosis of pulmonary embolism (blood clots in the lung vessels), although CTPA may detect more clots, according to a study in the current issue of JAMA: The Journal of the American Medical Association.
