 Law, Education, Religion are Names We Give to Adaptation

The changes in the conditions of human life during the last twenty or thirty thousand years have been mainly brought about by the acceleration of invention through increasing co-operation and the release of material and social power. There have been no doubt climatic and geographical changes, but their share has been relatively less important. The essential story of history and pre-history is the story of the adaptation of the social- educated superstructure of the animal man to the novel pro...

 A Cerebral Cortex Makes Animals Programmable

As we ascend the scale of cerebral development the possibility of teaching increases. It becomes possible to domesticate and train these higher-brain animals in just the measure that their brains are developed. You can teach very little to a fish or a reptile, but directly you come to the higher cerebral mammals you are confronted by the new possibility of establishing an artificial, taught, motive system to control, supplement or altogether replace natural instinct. You must catch them young...

 5 ways to maximize your cognitive potential Andrea Kuszewski

1. Seek Novelty There is only one trait out of the "Big Five" from the Five Factor Model of personality (Acronym: OCEAN, or Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism) that correlates with IQ, and it is the trait of Openness to new experience. People who rate high on Openness are constantly seeking new information, new activities to engage in, new things to learn—new experiences in general [2]. 2. Challenge Yourself Efficiency is not your friend when it co...

 LSD Mimics a Baby's Brain

So let's think. What is it like to be a baby? What's it like to be a child? Our emotions go up and down. We might be in a sort of happy, sort of ecstatic state one minute, giggling, finding everything funny and silly - similar things happen on psychedelics - and then the next minute there's a sudden shift and we're bawling our eyes out, you know? Similar kind of emotional sensitivities and hyper-imaginative processes occur with a psychedelic. Also something quite intriguing is that sense of ...

 Orwell Notes Hitler's Rigidity of Mind

It is a sign of the speed at which events are moving that Hurst and Blackett’s unexpurgated edition of Mein Kampf, published only a year ago, is edited from a pro-Hitler angle. The obvious intention of the translator’s preface and notes is to tone down the book’s ferocity and present Hitler in as kindly a light as possible. For at that date Hitler was still respectable. He had crushed the German labour movement, and for that the property-owning classes were willing to forgive him almost...

He notes that Hitler's ideas did not change at all over 15 years and that is a mark of madness.

 Specialization is the Way to Extinction

Now let us examine more closely what we know scientifically about extinction. At the annual Congress of the American Association for the Advancement of Science, as held approximately ten years ago in Philadelphia, two papers were presented in widely-separated parts of the Congress. One was presented in anthropology and the other in biology, and though the two author-scientists knew nothing of each other's efforts they were closely related. The one in anthropology examined the case histories o...

Specialization comes at the cost of general adaptability. So when the environment changes, the highly-specialized go extinct.

 Cognitive Neoteny in Modern Humans

The boy-genius can be seen as a specific instance of psychological neoteny which is apparently adaptive in modernizing cultures, and it occurred early in science because science is one of the most ‘modern’ and advanced social systems [2]. ‘Neoteny’ refers to the biological phenomenon whereby development is delayed such that juvenile characteristics are retained into maturity. It represents a relatively fast and simple way of evolving adaptations – for instance modern humans in Weste...

Perpetual education and change has pushed humans into a perpetual state of youthful cognition. Our brains remain childlike in order to continue to learn and adapt to our ever-changing modern environment.

 Cognitive Benefits of Bilingualism

In stark contrast to early suspicions that bilingual children were at risk of retardation or at best, “mentally confused” (Bialystok, 2005), recent research links bilingualism to cognitive reserve and suggests it may offer protection against dementia in old age. Cognitive reserve describes a kind of resilience which appears to mediate the relationship between brain pathology and the clinical expression of that pathology; it is thought that this resilience derives from more efficient use o...

 The Growth Mindset

In a recent study, a group of psychologists decided to see if this differential reaction is simply behavioral, or if it actually goes deeper, to the level of brain performance. The researchers measured response-locked event-related potentials (ERPs)—electric neural signals that result from either an internal or external event—in the brains of college students as they took part in a simple flanker task. The students were shown a string of five letters and asked to quickly identify the midd...

 NgR1 Improves Brain Plasticity in Adult Mice

Experience rearranges anatomical connectivity in the brain, but such plasticity is suppressed in adulthood. We examined the turnover of dendritic spines and axonal varicosities in the somatosensory cortex of mice lacking Nogo Receptor 1 (NgR1). Through adolescence, the anatomy and plasticity of ngr1 null mice are indistinguishable from control, but suppression of turnover after age 26 days fails to occur in ngr1−/− mice. Adolescent anatomical plasticity can be restored to 1-year-old mice ...

The plasticity lost from our youth is revived in mice by deletion of Nogo-A ligand.
