Learning and memory is enhanced by sleeping. New structural evidence linking sleep to these two aspects has been found by researchers at Langone Medical Center, New York University (NYU). The researchers used mice in their study. It was established that more dendritic spines developed in those mice that slept after learning a particular task. The dendritic spines are important for transmitting information across the synapses in the brain. They develop from the brain cells, li

Sleep apnea may be even more dangerous for women than for men, a new study suggests. Epidemiological studies have linked sleep apnea to heart disease in men, but the differences in risk between men and women have been largely unexplored. For the current study, researchers measured sleep quality electronically in 737 men and 879 women, average age 63, who were free of cardiovascular disease at the start of the study. They also tested all of them for troponin T, a protein that
