This is your brain. This is your brain's blood flow, courtesy of brain scan technologies. And this is dopamine, a neurotransmitter in the brain that plays pivotal roles in learning, memory, addiction and movement. MIT and Caltech scientists have created new molecular sensors that allow them to track dopamine for the first time, and provide the most direct detection ever of brain activity.
The new sensors work with one of the golden standards of neuorimaging. Functional magnetic resonance imaging (fMRI) typically tracks hemoglobin -- an oxygen-carrying molecule -- based on hemoglobin's faint magnetic properties. The resulting brain scans can measure blood flow to indirectly gauge brain activity, and have allowed researchers to study everyone from freeloaders to comatose patients.
But scientists figured that they could develop new molecular fMRI sensors that bind to specific neurotransmitters, or the chemical messengers that help transmit signals in the brain. The MIT/Caltech effort represents the first sensor that can hone in on a specific neurotransmitter, and may also lead to sensors for other neurotransmitters.
The breakthrough involved playing with a protein called cytochrome P450, which appears in most organisms and has weak magnetic properties. Researchers created many different mutated forms of the protein's gene, inserted the gene into E. coli bacterium to produce the protein, and then tested each protein variant for its ability to bind with dopamine.
The best candidates ended up being mutated again for the next round of improvement, in a strategy dubbed "directed evolution."
Five rounds eventually produced two sensors that bind strongly to dopamine, and thereby allow fMRI to detect it. The concept worked when researchers injected the dopamine sensors into the brains of rats, although the imaging only worked near the injection site.
MIT scientists hope to program brain cells to automatically express the dopamine sensors, as a noninvasive way of studying the brains of animals. These and other neurotransmitter sensors could eventually lead to better wiring diagrams of how brain regions work together -- truly a dope future.
Haha. Dope future.
The Sixth Sense - New GROUNDBREAKING Book in 2012! The Sixth Sense leads to Enlightenment
DNA Healing Code - Hardwired in ALL Humans
As an example of what I mean by “Groundbreaking” info that can be found in the 2012 release of my new book on The Sixth Sense (not yet titled )…..
There is a sequence required to communicate with Infinite Intelligence – to gain insight and/or much more complicated yet achievable, HolisticDNA Energy Healing. The sequence required is on multiple simultaneous levels, not just “step by step” like an instruction manual for assembling a piece of furniture.
The “Key” sequence has to do with applying known facts, beliefs, emotions and faith (not religious) – if not applied exactly as detailed, the Sixth Sense will remain dormant, and not be “activated”. As an example:
in theory --
you won’t find this in any existing text, which is why The Sixth Sense is so rarely utilized and hard to confirm. This will allow the Scientific Community to experiment and confirm my claims — remember, just a few decades ago, it was impossible to have a Man walk on the moon. Time for the next impossible to be challenged and confirmed — real
