Wow, I just stumbled upon Neurophilosophy's blog describing this interesting disorder where an individual has a difficulty forming cognitive maps of their environment (no brain damage required). I've had navigational problems before and I can't help but wonder if I suffer from topographagnosia. Good thing I use Googlemaps more frequently! Perhaps my hippocampus isn't screwed after all!

Introducing alpha calcium/ calmodulin-dependent protein kinase II (αCaMKII), the new memory eraser! Overexpression of this enzyme in the mouse brain deletes short and long term memory. The future treatment for PTSD? We shall see...

Correct me if I'm wrong but it seems that fluid intelligence is something that we are born with while crystallized intelligence is something we acquire over time. Motivation seems to play a larger part in the latter intelligence but I'm sure it does with the former as well. I pass along an interesting blog entry from Deric Bownd's MindBlog :

I wonder whether increasing internet use and decreasing interpersonal interaction among children have anything to do with the rising incidence rates of autism spectrum disorders. Does extended isolation negatively effect mirror neuron development and other vital areas of the social brain (imagine a child interacting with online virtual objects on a computer screen instead of with his peers outside in the park)? Or is it the other way around (autistic children prefer to spend more time in front of the computer screen rather than interact with peers)? This would be an area worth further investigation.

What a frustrating experience that I've had today with Citibank. 4 customer service representatives giving me inaccurate information about my percent back on special purchases! 2 reps said 3%, 1 rep said 4%, and the rest said 2%. Ridiculous...take their word for a grain of salt because half of their staff are apparently nubs. Better yet, go with the Chase Freedom card. 3% percent on your top 3 types of purchases.
