Ayahuasca, Neurogenesis and Depression | Ayahuasca.com: Ayahuasca, Neurogenesis and Depression By Daniel Mirante ? May 4th, 2008 ? Category: Neurosciences, Spirit & Healing Ayahuasca, Neurogenesis and Depression Recent scientific research suggests that neurogenesis ? the growth of new brain cells ? is a key to curing depression. People suffering depression have an enlarged amygdala, a structure deep in the brain, which produces amongst other things stress hormones. An enlarged, overactive amygdala may produce too much cortizol, a fight-or-fligh t stress hormone. Too much cortizol can whittle away neural structures - especially in the hippocampus which is the cortizol shut off Recommended Reading : How Prozac Affects the Brain http://www.new scientist.com/ article/dn9171 -how-prozac-af fects-the-brai n.html Repairing the Mind http://www.new scientist.com/ article.ns?id= mg17924082.500 The Anatomy of Dispair http://www.new scientist.com/ article.ns?id= mg18224455.700

Co-Treatment with Diazepam Prevents the Effects of Fluoxetine on the Proliferation and Survival of Hippocampal Dentate Granule Cells: "These results suggest that benzodiazepine s might interfere with the clinical effects of fluoxetine or that increased neurogenesis is not a valid model for the delayed onset of the clinical antidepressant effects."

Princeton - News - Scientists Discover Addition of New Brain Cells in ...: 1. "In a finding that eventually could lead to new methods for treating brain diseases and injuries, Princeton scientists have shown that new neurons are continually added to the cerebral cortex of adult monkeys. The discovery reverses a dogma nearly a century old and suggests entirely new ways of explaining how the mind accomplishes its basic functions, from problem solving to learning and memory." 2.Within the cerebral cortex, the researchers found neurogenesis in three areas: 1) the prefrontal region, which controls executive decision making and short-term memory; 2) the inferior temporal region, which plays a crucial role in the visual recognition of objects and faces, and 3) the posterior parietal region, which is important for the representation of objects in space."

Electrodes spark neuron growth : Nature News Nicola Jones: Deep brain stimulation could help make memories. Electrodes inserted into certain parts of the brain ? in a technique known as deep brain stimulation ? can stimulate the growth of new neurons that are used in memory formation, according to research in mice. The findings show that artificially created neurons can be fully functional ? a topic of hot debate in the neuroscience community. Knowing that the cells are functional, rather than just useless growths, is a boost for those seeking to use the treatment against Alzheimer' ;s disease and other memory-degener ation disorders. "I'm hoping to help people who have difficulty remembering things," says Scellig Stone, a neurosurgery resident and PhD candidate at the University of Toronto.

Neurogenesis-D ependent and -Independent Effects of Fluoxetine in an Animal Model of Anxiety/Depres sion: In mouse model of chronic corticosterone treatment, efficacy of fluoxetine is blocked in some, but not all, behavioral paradigms when neurogenesis is disrupted. In addition, mice deficient in beta-arrestin 2 displayed a reduced response to fluoxetine in multiple tasks.
