(PhysOrg.com) -- Learning a feeling of safety activates cellular and molecular processes that act against depression. This has been analysed using a new animal model that helps examine and explain the relevant cell biology processes more effectively. The findings now published in the journal Neuron show that "learned safety" can have an anti-depressive effect comparable to pharmacological antidepressants but that this effect is controlled by other molecular processes. The project supported by the Austrian Science Fund FWF was carried out by the Howard Hughes Medical Institute at Columbia University in the U.S. http://www.physorg.com/news148575145.html Medicine & Health Mon, 15 Dec 2008 14:52:25 EST news148575145 A new animal model has provided insight into the cellular and molecular mechanisms associated with behavioral therapy for depression. The study, published by Cell Press in the October 9th issue of Neuron, may provide a good model system for testing cellular and molecular interactions between antidepressive medications and behavioral treatments for depression. http://www.physorg.com/news142703589.html Medicine & Health Wed, 08 Oct 2008 16:53:09 EST news142703589 Why do some people have the ability to remain calm and relaxed even in the most stressful situations? New experiments in mice by Howard Hughes Medical Institute (HHMI) researchers are providing insight into how the brain changes when the animals learn to feel safe and secure in situations that would normally make them anxious. http://www.physorg.com/news142686357.html Medicine & Health Wed, 08 Oct 2008 12:05:57 EST news142686357
