The frontal reading system has been implicated in phonological processing and semantic processing (word analysis). This is also where Broca’s area is found. Broca’s area is involved in language processing, speech production, and comprehension. Neuron activation is increased in this area when words are spoken (Devlin…
Beginning in infancy and throughout the life span, humans are motivated by newness, change, and excitement. Habituation, the tendency to lose interest in a repeated event and gain interest in a new one, is one of the most fundamental human reflexes. If the thermostat were to suddenly turn the air conditioning on, you…
We supposed at first that the mental unity of these little avians was telepathic, but in fact it was not. It was based on the unity of a complex electromagnetic field, in fact on "radio" waves permeating the whole group. Radio, transmitted and received by every individual organism, corresponded to the chemical nerve…
Although the ages of Teilhard de Chardin (1881-1955) and Vernadsky (1863-1945) differed, they were at the comparable level of scientific maturity concerning the growth of their biosphere — noosphere theories. Vernadsky first presented his views on the biosphere systematically when he published The Biosphere 2in 1926…
As a species, humans manifest a quality called neoteny, the retention of juvenile characteristics into adulthood. Neoteny has physical ramifications—scarce body hair and a flat face are two examples—but it also has neurological ones. Namely, we have an extraordinary capacity to continue learning throughout life. If…
While detecting an ET intelligence would overturn terrestrial religions forever, detecting a global internet intelligence would have wide-ranging ramifications for society. We'd have daily contact with an AI much larger than us, one that presumably would be steadily increasing in power every 18 months (Moore's Law)…
why is hair so rapidly replaced, after cut out ?and why is it so difficult to keep from growing ?hair is more important than we realise Each part of the body has highly sensitive work to perform for the survival and well being of the body as a whole.The body has a reason for every part of itself
When faced with complexity, our first response is to retreat to the familiar, even if the familiar means failing. But in addition to reverting to what is familiar, we also have another reaction: fear. We are hardwired to perceive real change as threatening, so we instinctively reject it. Sure, a few of us have the…
Even something that has been traditionally seen as the purview of the young—the ability to learn new languages —continues to change the landscape of the brain late into life. When a group of adults took a nine-month intensive course in modern standard Chinese, their brains’ white matter reorganized progressively (as…
In Man the brain presents an ascensive step in development, higher and more strongly marked than that by which the preceding subclass was distinguished from the one below it. Not only do the cerebral hemispheres overlap the olfactory lobes and cerebellum, but they extend in advance of the one, and further back than…
Not all babies are the same. Human babies are rather helpless, interested mostly in food, sleeping, eating, defecating, and comfort. Compare human babies with newborn deer. When fawns are born, they immediately stand up and soon are able to run away from danger. Scientists call these two types of babies in the animal…
