by Tabea Kemna, Karolinska Institutet In an interdisciplinary study combining stem cell biology and tumor biology, researchers from Karolinska Institutet (as well as Uppsala and Lund University, together with researchers in Canada, Germany and France), have succeeded in creating a new type of stem cell model for studies on cancer of the brain. The study...
by University of Bologna research group from the University of Bologna has succeeded in modifying the negative effect of a returning memory that triggers fear, and developed a new non-invasive experimental protocol. The result of this study, published in the journal Current Biology, is an innovative protocol that combines fear conditioning—a stimulus associated with something...

by Universitaet Mainz After 21 days in vitro, hippocampal neurons of the rat form many synaptic contacts and communicate with each other. Within the study such neuronal networks cultivated on multi-electrode arrays were used to invest the synaptogenic function of α2δ-subunits.

Does sleep improve learning by enhancing skills while people snooze,...
by Massachusetts Eye and Ear Infirmary In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by...

By Rich Haridy July 15, 2020 New research is illustrating the differences in toxic protein accumulations in the brains of older subjects suffering cognitive decline compared to older subjects with unexpectedly strong cognitive abilities. An image compiled from PET scans of these so-called “super-agers” has won Image of the Year from the Society of Nuclear...
by Jennifer Brown, University of Iowa The hormone FGF21 is made in the liver and acts in the brain to suppress sugar intake and the preference for sweet taste. The cartoon illustrates the role FGF21 plays in food choices.Understanding the biological mechanisms that control sugar intake and preference for sweet taste could have important implications...
