A Neuron’s Obsession:

In their most recent work this year, the research team reported that a single human neuron could recognize a personality through pictures, text or the sound of a name — no matter how that person was presented. In tests, one brain cell reacted only to Oprah Winfrey; another just to Luke Skywalker; a third singled out Argentine soccer star Diego Maradona.

Each neuron appeared to join together pieces of sensory information into a single mental impression. The researchers believe these cells are evidence that it only takes a simple circuit of neurons to encode an idea, perception or memory.

Nature’s clones: What Twins have taught us:

Twin studies of this kind have yielded some startling insights into how influential genes are in shaping our behaviour. “Well conducted twin studies are able to completely change the way we view problems and to reorient entire research programs,” says Martin. “For instance, autism had been attributed to a variety of causes, such as emotional coolness in the mother, until a landmark twin study found much higher concordance in monozygotic than dizygotic twins.”

Indeed, this was covered pretty clearly in my Psych 101 textbook, oddly enough.

One 1996 study in the journal Psychological Science even found that happiness appears to be primarily determined by our genes. It discovered that socio-economic status, education, income, marital status or even religiosity could account for no more than three% of the variance in happiness. Genes, on the other hand, appeared to account for around 50%.

It would be really interesting if they had a pair of twins involved in the epilepsy experiments (first article) to see if the neuron mapping is the same in twins. The impact on epistemology would be worth wrestling with, as well as the impact on free will. Cognitive psychology is worth its weight to philosophy.
