			<content:encoded><![CDATA[<p>I think Love is a wonderful thing that should be celebrated, and to that end I&#8217;d like to wish all the lovers out there a great day with their significant others.</p>
<p><strong>Confusing Love and Happiness<br />
</strong></p>
<p>I take issue today with the institution of Valentines Day, which masquerades as a supporter of love, happiness, and all things good about personal relationships, concealing an insidious second purpose just beneath the surface.  VDay, with the help of our Advertising and Media, manages to juxtapose happiness and love for the purposes of making the argument that a persons happiness and fulfillment have a dependent relationship to love or, errm, relationships.</p>
<p><span id="more-684"></span><strong>The Hidden Associations in VDay</strong></p>
<p>To understand why I seem to loathe the existence of such a day we need only consider the long-held associations with it that reside silently in my mind.  To follow the somewhat chaotic jumping of logic below you must understand that the brain forms associations between all sorts of things and when you think about VDay it will look at memories from past relationships, heartbreaks, triumphs, failures, and anything remotely associated with your current feelings on VDay.</p>
<p>If you&#8217;ve ever been in a relationship during VDay your mind has not forgotten and will bring up the memories linked to relationships when you think about it, because it has formed an association between the two.  You can see then that if you&#8217;re in a relationship this year, likely thinking about VDay summons feelings of warmth and compassion, love, etc.  On the other hand if you&#8217;re single this year without a valentine, thinking about VDay may summon back unhappy memories from your collective pool of associated memories, perhaps a past VDay or relationship gone wrong.</p>
<p>The point here is that you, as a person, have an abundance of positive and negative associations already made up in your head for VDay, whether you know it or not.   Once you realize that, my argument that VDay sucks comes into focus.  Because within us all is the capacity to feel good or bad about VDay, the mere act of celebrating it suggests a good/bad relationship; you either have a valentine or you do not.</p>
<p><strong>If noone is your Valentine on VDay, you are unloved</strong></p>
<p>Once you&#8217;ve accepted my argument that associated past experience and memories are triggered when exposed to VDay&#8217;ish things, you need only look to the real world for examples of how knowledge of this can be exploited for financial gain.  Advertisers carefully craft their media to express to people very specific messages that support the argument that you NEED to participate or you don&#8217;t love your partner, or that you NEED to find a partner to participate with or you are not loved.</p>
<p><strong>Defeating VDay&#8217;s Negative Associations<br />
</strong></p>
<p>How can I defeat a day?   Well, I certainly can&#8217;t defeat February 14th as a calender day, I&#8217;ve tried that, it just comes back next year.    What I can do is choose to form new associations in mind with VDay.  In doing this, I can choose to respect the essence of VDay, which is the uplifting of love, without falling victim to it&#8217;s insidious consequences when viewed through a commercial lens.  What I mean by that is I have chosen today to be thankful for the love I have of knowledge.   The pursuit of more efficient ways to get things done, a deeper understanding of reality, a more complete understanding of my self; all these things I love to seek out, and this has been constant throughout my life.</p>
<p>So today I choose to show my love for knowledge and the pursuit of understanding, by associating this exercise in deconstructing my feelings on VDay with the day itself.</p>
<p><strong>Singularly Triumphant</strong></p>
<p>But why choose to associate writing this blog post with VDay?   Certainly it could be just by chance, but it has a particularly interesting feature in that associating this exercise with this day defines a sort of self-referencing association in that in this exercise I considered how I feel about this day, and in writing this blog I&#8217;ve put into words how I feel about this day.</p>
<p><span style="color: #000000;">Then again, perhaps &#8220;Gödel, Escher, Bach&#8221; actually is eating my brains.</span></p>

<p>In response to a <a href="http://www.justindujardin.com/blog/?p=419" target="_self">blog post</a> I wrote recently, a friend kindly pointed out that I seemed to have overlooked the work of Dr. Eric Kandel and others with respect to molecular changes that occur in neurons during learning.  In 2000 <a href="http://en.wikipedia.org/wiki/Eric_Kandel" target="_blank">Eric Kandel</a> was awarded the Nobel Prize along with <a title="Arvid Carlsson" href="http://en.wikipedia.org/wiki/Arvid_Carlsson" target="_blank">Arvid Carlsson</a> and <a title="Paul Greengard" href="http://en.wikipedia.org/wiki/Paul_Greengard" target="_blank">Paul Greengard</a> for their work detailing such molecular changes.  As it turns out because of their work, we actually have a pretty fantastic understanding about how things are committed to short and long-term memory, as well as the general way in which synaptic connections relate to the storage of things in memory.</p>
<p><strong>Nobel Lecture 2000</strong></p>
<p>My friend also provided a link to <a href="http://nobelprize.org/nobel_prizes/medicine/laureates/2000/kandel-lecture.html" target="_blank">the lecture</a> that Kandel gave while he was in Stockholm accepting the Nobel Prize.   I must admit that very little of the talk made <em>complete</em> sense to me, partly because the camera man chose not to show the screen while Kandel was using his laser pointer to go through the diagrams, and partly because I&#8217;m not a molecular biologist.   A few very cool insights did come out of watching the lecture, that are interesting enough to share&#8230;</p>
<p><strong><span id="more-489"></span>Remembering Through Repetition</strong></p>
<p>At one point or another in life you&#8217;ve probably run into someone that is keen on using repetition to help you remember things.   Be it a grade-school teacher or a parent trying to help you study for a test, this is a bit of common knowledge that has been around for years, and it would seem Kandel confirms that this is a legitimate way to commit things to long term memory.   In fact during his lecture he goes to great lengths to graph and show the effect repetition has on the length of time something is stored in memory for recall.   A single stimulation resulting in storage for just a few hours, while repeated stimulation (5 times) causes new protein synthesis, committal to long term memory, and recall for long periods of time.</p>
<p><strong>Stronger vs New Synaptic Connections</strong></p>
<p>Another interesting point Kandel and his fellows have brought to light is the distinction between what causes synaptic connections to strengthen, and what causes new synaptic connections to be formed.   In all of their testing cases, short-term memory storage involved only the modification of strength in existing synapses.   On the other hand, long-term memory storage has been associated with both modification of the strength of existing connections, as well as the formation of entirely new synaptic connections.  To be clear modification could mean strengthening or weakening of a synaptic connection.</p>
<p><strong>CREB2 the bouncer<br />
</strong></p>
<p>By far the most interesting thing to take away from this presentation was the process by which things are committed to long-term memory.   As I mentioned above, repetition seems to be the key factor in committing things to long term memory, but what&#8217;s more is that Kandel has figured out the reason for this.   In order for things to be committed to long-term memory, there needs to be new protein synthesis and part of new protein synthesis in a neuron requires activation of what is called the CREB1 transcription factor.   The catch is that CREB1 is repressed by another transcription factor called CREB2.   At this point you may have guessed that when you create the same stimulation in the neuron multiple times, eventually CREB2 let&#8217;s down its guard and CREB1 can be activated, which allows the process to continue and the memory to be committed to long-term storage.   Put in other words repeated stimulation acks like a secret handshake in the neuron that convinces CREB2 the bouncer to let in to the long-term memory storage party that&#8217;s happening just behind the door.  Kandel speculates that when there is a deficit in CREB2, this may be the reason behind certain individuals having photographic memories.  In fact they have observed this to be true in mice&#8230;</p>
<p><strong>Oh but to be a mouse<br />
</strong></p>
<p>In ending his lecture Kandel talked about some interesting thoughts about the clinical applicability of this research.   In particular he notes that as people tend to age, there are a number of disorders that affect their ability to convert short-term to long-term memory.   In experiments on mice Kandel and his team have been able to show that this is caused by a single defect that makes it difficult to initiate the transcriptional cascade process that was talked about earlier as being responsible for the storage of things into long-term memory.   By using their magic to overcome this deficit, they have been able to produce flash-bulb memory in mice.   As Kandel himself jests.. &#8220;So if you&#8217;re a mouse, we can really help you with age-related memory loss&#8221;</p>
<p>While we may not be to a point that we can come up with a convenient little pill to help us convert things to long-term memory storage, the idea that it is possible in the future is quite appealing.</p>
