IUPUI mathematician receives $1.4 million to study link between respiration and high blood pressure in sleep apnea

INDIANAPOLIS -- Sleep apnea affects an estimated 25 million adults in the United States and is associated with increased risk of hypertension, stroke, heart attack and heart failure.

Obstructive sleep apnea is characterized by recurrent upper airway collapses resulting in brief interruptions of breathing during sleep. Episodes occur repeatedly. Untreated obstructive sleep apnea has cumulative effects on the cardiovascular system, leading to hypertension that may be drug resistant. It is estimated that half of all individuals with obstructive sleep apnea are hypertensive.

Indianapolis Brain Bee winner thrives at national competition

INDIANAPOLIS -- The Eighth USA National Brain Bee Championship, a neuroscience competition for high school students, was held at the University of Maryland Medical and Dental Schools in Baltimore on Friday and Saturday, March 20 and 21, 2015.

Winners from 52 regional competitions in 28 states tested their knowledge of the human brain at the national level, where topics included intelligence, emotions, memory, sleep, vision, hearing, sensations, Alzheimer’s disease, Parkinson’s disease, schizophrenia, addictions and brain research.

41 Science Students Named in Top 100 for 2015

INDIANAPOLIS -- “We are very proud of these Top 100 honorees,” said Dean Simon Rhodes. “They have taken full advantage of the integrated academic, research, leadership and community engagement opportunities that are uniquely found in the School of Science and at IUPUI.”

With 41 students on this year’s list, the School matches it record year in 2014. Last year, 12 of those were named among the Top 20 students on campus.

How alcohol hijacks brain's reward system: $545,000 award funds IUPUI investigation

INDIANAPOLIS -- Scientists have only a rudimentary understanding of how alcohol affects neurons in the brain. It is known that, as any addictive drug, alcohol directly or indirectly acts on a specific population of brain cells, called dopamine neurons. Through this action, the neurotransmitter dopamine is released, which evokes feelings of pleasure. However, the biological mechanisms of how alcohol evokes dopamine release have not been determined; exploring this question is the major goal of the grant.
