Developing Intelligence

Blogging on the Brain: 11/30

A lot of good brain blogging lately; some beautiful drawings from the era of phrenology, some crazy kids high on scopolamine, James Flynn’s current thoughts on intelligence, and more…

Who has better graphics? It’s a close call between the phrenology of old and today’s fMRI.

Beware the No2 Pencil – even low levels of lead exposure can lead to cognitive decline.

Getting high on scopolamine is not a good idea, but videos of it are pretty entertaining.

Mind, the time-machine: video proof (at the bottom) that hippocampus travels to places you haven’t been yet.

The speed of thought in memory consolidation?

Interesting speculation about brain imaging implants.

The wire-mother experiment for the new millenium: toddlers cuddle robots!

Flynn argues that intelligence is like the atom (disregard the physics envy)

Slides and videos from NIPS ’06 – including a lecture on systems level modeling of biological data and another on Bayesian models of learning & inference.

A new – and very versatile – network algorithm. Seems to compute path propagation in networks of with varying geometries and association weights.

Does PFC train intraparietal sulcus in mapping numbers to symbols?

    Thank goodness pencil “lead” is actually graphite.

    (Sorry, couldn’t resist.)

    This is from your speed of thought link above:
    …During sleep, the reactivated memories of real-time experiences are processed within the brain at a higher rate of speed. That rate can be as much as six or seven times faster, and is described as “thought speed.”
    As a former computer guru I learned early on to quit saying, ” That is impossible, or they will never do that”
    This little tidbit from your link has me making a note for future reference that some biochemist is going to figure that all out and eventually I am going to be thinking 6 or 7 times faster! LOL! I wonder if that will hurt! LOL!
    Dave Briggs :~)
