Study shows how LSD interferes with brain's signalling

A group of volunteers who took a trip in the name of science have helped researchers uncover how LSD messes with activity in the brain to induce an altered state of consciousness.

Brain scans of individuals high on the drug revealed that the chemical allows parts of the cortex to become flooded with signals that are normally filtered out to prevent information overload.

The drug allowed more information to flow from the thalamus, a kind of neural gatekeeper, to a region called the posterior cingulate cortex, and it stemmed the flow of information to another part known as the temporal cortex. [...] The scientists wanted to test a hypothesis first put forward more than a decade ago. It states LSD causes the thalamus to stop filtering information it relays to other parts of the brain. It is the breakdown of this filter that gives rise to the weird effects the drug induces, or so the thinking goes.

    Any gun restrictions that the Supreme Court agrees don't violate the 2nd amendment would be applied equally to all citizens.

    So, no, your equivalency is false.

    First of all, I meant to use the plural parts. You singled out the second amendment not me. I'll bite anyway. Statistically speaking I agree that Republicans are more likely to like guns. A ban on tampons affects men and women equally by your logic though.

    You can fix that statement by removing some words : "Any gun restrictions violate the 2nd amendment."
    I am not in the USA but any reading of the second amendment makes it quite plain that any law that restricts weapons at all is unconstitutional, regardless of what excuses the SC may make to allow them. They should strike down every arms control law until 'the people' amend the constitution, and update the 2nd to fit a modern society.
