The science of smell – smell as molecular vibration.

(adsbygoogle = window.adsbygoogle || []).push({});

Relevant to brain studies, behavior studies (smell and molecular communication play a larger role than most people realize in behaviors and experience), and the popular topic and theme of ‘vibration’ in the esoteric culture materials… How a new science and industry of scent chemicals is evolving from chemists and […]

Memory as a search problem

This Sciam article discusses a recent experiment with memory, that illustrates some of the complex detail that our memory can store. The experiment demonstrated that with a visual image to trigger memory recall, ordinary humans were able to quickly match and compare a really large number of details.

I thought a boingboing’s poster’s take on […]

Neuro Cards

What do a neurotoxic pufferfish, an iron rod blown by blackpowder thru the brain and skull, a split brain, and an enriched environment neuron all have in common?

You can get them as free .pdfs for printing neuro cards from Accidental Mind.

MDMA causes Oxytocin release in studies

From New Scientist – one of the better science email newsletters, incidentally:

Ecstasy really does unleash the love hormone

“Clubbers who take the “love drug” ecstasy really might be “loved up”. Studies in rats suggest the drug causes a brain surge of oxytocin – the hormone that helps bond couples, as well as mothers to […]

“Neurotheology” – is the brain built to produce thoughts of god?

This is a fairly shallow article, mostly interesting because it appears on the CNN website.

http://www.cnn.com/2007/HEALTH/04/04/neurotheology/index.html

“”When we think of religious and spiritual beliefs and practices, we see a tremendous similarity across practices and across traditions.”

The frontal lobe, the area right behind our foreheads, helps us focus our attention in prayer and meditation.

From this article:

His argument is based on the fact that for more than 99 per cent of human evolutionary history, we have lived as hunter-gatherer communities surviving on our wits, leading to big-brained humans. Since the invention of agriculture and cities, however, natural selection on our intellect has effective stopped and mutations have accumulated in the critical “intelligence” genes.

“I would wager that if an average citizen from Athens of 1000BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions, with a good memory, a broad range of ideas and a clear-sighted view of important issues,” Professor Crabtree says in a provocative paper published in the journal Trends in Genetics.

“Furthermore, I would guess that he or she would be among the most emotionally stable of our friends and colleagues. I would also make this wager for the ancient inhabitants of Africa, Asia, India or the Americas, of perhaps 2,000 to 6,000 years ago,” Professor Crabtree says.

“The basis for my wager comes from new developments in genetics, anthropology, and neurobiology that make a clear prediction that our intellectual and emotional abilities are genetically surprisingly fragile,” he says.
