(the last slide of 30, from The Oregon Health and Science University) -- for those interested in Computational/Theoretical Neuroscience, some very intriguing depictions . . . for those not interested, inanity.

To be fair to Rick

-- who is a nice young man with whom I have chatted in a congenial manner . . .

He is right to expect some hook to plunge him into the depths of the neurocircuitry of the Mormyrids (the fun comes in looking at all the slides and reading all the notes, as the fiendish researchers cram sensors into the racked fish's brain, paralyse him, shock him, run virtual reality models on his paralyzed brain, and watch his paralyzed attempts [the electrosensory organs are still active] to make sense of his world on their plasma screens).

So:

17) Adaptation of Sensory Responses. Now if we run the simulation with the same pairing procedure as shown earlier, the results can be compared with experiment. First, only the command signal which brings a series of synaptic inputs to the medium ganglion cell, then during every cycle pair the sensory image of the electric organ discharge with the electrosensory input to get a pause-burst response. After some time, the synapses change:they are relatively enhanced during the pause for a lack of broad spikes, and depressed for many broad spikes. Then when the sensory stimulus is turned off, the negative image is revealed, and slowly fades.

Marching orders from Emperor Norton II

You are funny, Rick! It's difficult for me to 'explain this brain stuff' in words, since it was images and animations that intrigued me (and which I thought might interest you). I'd rather you and others interested have a gander, instead of me giving you a load of bumf. But, hey, live and learn . . .

. . . if you want me to clean your toilets, you will have to offer me something of value in return. You will have to show me that you are not afraid of hyperlinks (we have to get you exploring this internet thing. One thing leads to another, in a rather astounding fashion, you see. By clicking the little blue things I was able to discover that the Mormyrids have a huge brain in relation to the rest of their bodies -- and that they use up to 60% of their oxygen to sustain it).

By the way, who are the other recruits/inductees/draftees in the Rick Army of Contrarians? -- or are you emulating Norton I, Emperor of the United States?

Hey!

I explicitly said "link me no links" but to explain this brain stuff in your own words.

But no.

You're useless at taking orders, pal. You're never going to be in the Rick Army. Not even to clean the dunnies. Not with this attitude!
