Addicting Mice To Light

Al writes "In an attempt to better understand how the reward system in the brain functions in people suffering from addiction, scientists at Stanford have created mice that are addicted to light. They engineered light-sensitive proteins to trigger signaling pathways in the nucleus accumbens, a part of the brain that responds to pleasurable stimuli. They then connected a fiber-optic cable to this part of the brain and delivered a blast of light whenever the mice wandered into a 'reward chamber.' In previous experiments the mice have been given drugs like cocaine or amphetamine when they enter these rooms. The light treatment works in exactly the same way but lets the researchers very precisely control timing and dose of reward administered to the brain. The approach could also provide a way to probe receptors that cannot be accessed using existing drugs."

      You made an interesting point, though. I hadn't thought of that. However, I actually suspect that most of the geeky men probably are more reluctant to make the first move. They too are looking for fellow geeks, who are few and far between. With the additional expectation that they wouldn't have much of a chance with a non-geeky woman, they'd probably become conditioned such that they'd be less likely to make the first move even if they did meet a geeky woman.

In order for physical withdrawal to occur the drug has to act on the GABA system, whereas stimulants like: cocaine, amphetamine, caffeine, and nicotine act on the dopamine and serotonine systems. That isn't to say that stimulants are not addictive, just that they don't cause classic withdrawal symptoms.

      Now that we know more about how the brain functions, we can point to certain physical changes that occur within the brain when you expose it to dopamine/serotonine acting drugs, and can make a case that those changes cause a "physical withdrawal", but it's not the really the same thing. Complicating the theory of dopamine/serotonine drug withdrawal are studies showing you can also find the same changes brought about by other means, such as exercise or competition.

      It's difficult to discuss addiction because it such a socially loaded issue. Physical withdrawal, while unpleasant (and sometimes even potentially fatal) is not the primary cause or indicator of addiction. It can be an impediment to remission and recovery, but it's fairly well understood and easily dealt with medically. The primary cause of addiction and addiction relapse is conditioning (with its resulting cravings). As this study kinda suggests, you can become addicted to anything (even WoW) so long as your brain expects to receive a reward for a specific behavior. While drugs short circuit the reward pathway (and may therefor be more potentially addictive then WoW) you still have to take the drug, thus establishing a behavior-reward correlation.

    Haven't they already done experiments in the past where electrodes implanted in the brain can be used to stimulate sensations? If so, then there was no need to get clever with the proteins - put the electrodes in place, and then trigger them when the mice enter the lighted room. That seems more straightforward than adding photoreactive proteins that may have other unknown side-effects. But, then, me != biologist.

      This was really a proof-of-principle paper. Yes, you can get mice to addict themselves to electrical stim, but you can only present one kind of stimulus to the neurons (a big electrical shock), and you can't target specific types of cells.

      [Backstory: these same folks showed in 2005 that you could use these sensors to change the voltage level within the cell. That was hailed as the biggest neuroscience breakthrough in decades. Deisseroth is definitely close to the front of the line for the Nobel.]

      Their new method has 2 big advantages over electrical stim: the light sensor is *genetically encoded*, which means if you can find a gene that is only expressed in one type of cell, then you can trick that type of cell into making your light sensor for you. So now you can directly address only those cells that are making the sensor.

      Second, they have figured out how to connect the output of their sensor to specific chemical pathways inside the cell, so now instead of just jolting the cell and causing it to freak out and (hopefully also) fire off some spikes, you can now choose to activate some random signalling molecule. Truly mind-blowing. :)

    2. Re:Over-engineered? by omris · · Score: 1

      The real breakthrough here has to do with the fact that they can, like you mentioned, activate only one signaling pathway at a time. An electrode can only excite the whole cell, and not even one one kind of cell.

      Attaching the light sensitive bit onto different pathways, they even mention that some of the pathways they tried didn't produce the "addiction" behavior. It can provide a whole lot more information on exactly which signals are the ones that make you addicted, versus other pathways that activate the same chain of events down the line, but don't lead to the true "addiction" signals long term.

      It's actually pretty damn cool.
