Researchers May Have Discovered How Memories Are Encoded In the Brain

Zothecula writes "While it's generally accepted that memories are stored somewhere, somehow in our brains, the exact process has never been entirely understood. Strengthened synaptic connections between neurons definitely have something to do with it, although the synaptic membranes involved are constantly degrading and being replaced – this seems to be somewhat at odds with the fact that some memories can last for a person's lifetime. Now, a team of scientists believe that they may have figured out what's going on. Their findings could have huge implications for the treatment of diseases such as Alzheimer's."

Re:religious implications?

[Quartus486]

Can't answer for other religions, but this is what the Bible says:

Ecclesiastes 9 (New International Version)

  5 For the living know that they will die,
      but the dead know nothing;
they have no further reward,
      and even their name is forgotten.

10 Whatever your hand finds to do,
do it with all your might, for in the realm
of the dead, where you are going,
there is neither working nor planning
nor knowledge nor wisdom.

My mind is blown

I took a look at the paper in case I managed to understand something, and came across this:

Information Storage Capacity

If each extended kinase can either phosphorylate at the S-T site on a tubulin substrate, or not, the process effectively conveys one bit of information (e.g. no phosphorylation = 0, phosphorylation = 1). Each set of six extended kinases on either side of a CaMKII holoenzyme can thus act collectively as 6 bits of information. Ordered arrays of bits are termed âbytesâ(TM).
[...]

Logic Gates

Clusters of phosphorylated tubulin, and/or MAP attachment may serve as logic gates for propagating information. Figures 9 and 10 demonstrate two types of Boolean logic gates, an AND gate and an exclusive OR gate (XOR) in which MAPs convey inputs, with output along tubulin pathways. Figures 11 and 12 show AND and XOR gates in which MAPs convey output of inputs and processes in tubulins within the MT. The combination of XOR and AND logic gates forms a universal set for computation in which all other logic gates (NOT, OR etc.) can be conceived. Signals propagating through MT-MAP logic circuits may extend throughout cytoskeletal networks, regulating synaptic function, cognition and behavior.

Whoa. If that research is correct then that's really amazing.
