A ground-breaking proof

December 11th, 2006 · 1 Comment

Today I mathematically proved something that has long been suspected, but never confirmed in such a rigorous way.
I was working on my Models of the Neuron homework, and after three or four intense lines of arithmetic, I got back to the equation I started with.
What did this prove?
Well, I was feeling pretty tired today, as [...]

I have working neurons!

December 7th, 2006 · No Comments

After noticing a typo (hello missing negative sign!) in the paper, and debugging two typos in my implementation, I have what seem to be two working models (VCN bushy cells Types I-c and II). Here I’m applying a constant 100 pA stimulus to them. Already I see significant differences between the two cell types:

Programming + Espresso = Happy Brock

December 7th, 2006 · 1 Comment

At the moment I’m working on my Models of the Neuron Project #2. In particular, I’m coding a model of ventral cochlear neuron bushy cells, using Octave rather than Matlab.
I’ve also just had another shot of espresso from our new X6, and I’m listening to an all-string-instrument tribute to Radiohead’s OK Computer. It’s so beautiful [...]

I’ve still got:

my Models of the Neuron Project #2
my Models of the Neuron Homework #8
my Models of the Neuron Final Exam
Assorted Research (300 Cal. per serving)

to do before I drive down to New Orleans and then fly to Seattle for Wintereenmas. Today, despite a marathon 4-hour meeting I managed to:

Start my Models of the Neuron [...]

Mathematical Atrophy

December 3rd, 2006 · 3 Comments

Practical mathematical ability, like other parts of the body (since it is encoded somewhere in the brain), atrophies over time. By the end of high school, I was able to score a 5 on the AP calculus BC exam, which allowed me to skip Calc I & II at Tulane. Freshman year, I [...]
