Orexin/hypocretin neurons have a crucial role in the regulation of sleep and wakefulness. To help determine how these neurons promote wakefulness, we generated transgenic mice in which orexin neurons expressed halorhodopsin (orexin/Halo mice), an orange light-activated neuronal silencer. Slice patch-clamp recordings of orexin neurons that expressed halorhodopsin demonstrated that orange light photic illumination immediately hyperpolarized membrane…
Read MoreNew findings may lend insight into why some people are especially sensitive to bitter tastes. Scientists from the Monell Center and Givaudan Flavors have identified a protein inside of taste cells that acts to shorten bitter taste signals… Source: http://www.medicalnewstoday.com/releases/232142.php
Read MoreNicotine is the primary psychoactive substance in tobacco, and it exerts its effects by interaction with various subtypes of nicotinic acetylcholine receptors (nAChRs) in the brain. One of the major subtypes expressed in brain, the α4β2-nAChR, endogenously modulates neuronal excitability and thereby, modifies certain normal as well as nicotine-induced behaviors. Although α4-containing nAChRs are widely…
Read MoreScientists from the Freie Universität Berlin have identified mechanisms regulating chemical neurotransmission in the nervous system Scientists from the Freie Universität Berlin and the NeuroCure Cluster of Excellence, led by Volker Haucke in collaboration with colleagues from the Leibniz Institute for Molecular Pharmacology (FMP) in Berlin, have unravelled a mechanism… Source: http://www.medicalnewstoday.com/releases/232135.php
Read MoreNIH-funded scientists have developed a strain of mice with a built-in off switch that can selectively shut down the animals’ serotonin-producing cells, which make up a brain network controlling breathing, temperature regulation, and mood. The switch controls only the serotonin-producing cells, and does not affect any other cells in the animal’s brains or bodies… Source: http://www.medicalnewstoday.com/releases/231940.php

Read MoreThe following post was originally part of a presentation Eric Thompson gave on the Neuroscience of Meditation at the MindHive event at Naropa University in March, 2010. It is based on the research of Newberg and d’Aquili. Stage 1 Attention Association Area (AAA) in the right hemisphere is activated Eventually spreads to AAA in…
Read MoreDear Profound Meditation Friends & Community, Welcome! This is an initial blog to which your iAwake Technologies Team intends to add to regularly, to inspire, inform and support the transformational journey that you have begun, by using the Profound Meditation Program on a daily basis. I find it very easy to speak about this, as…
