All knowledge, all experience could be said to be a neural situation inside the skull, and the brain is not merely a receiver and recorder of input through the senses: it also has output because the way in which it structures its senses and nerve patterns shapes the input in the same way that a harpist, by selective…
This practice of meditation itself sharpens your mind and improves your memory, qualities that are certainly useful beyond spiritual practice, whether in business, engineering, raising a family, or being a teacher, doctor, or lawyer. This practice also helps on a daily basis with anger. When you get irritated, you can…
Then leave Complaints: Fools only strive To make a Great an honest Hive. T’ enjoy the World’s Conveniencies, Be famed in War, yet live in Ease Without great Vices, is a vain Eutopia seated in the Brain. Fraud, Luxury, and Pride must live Whilst we the Benefits receive. Hunger’s a dreadful Plague, no doubt, Yet who…
From animals to man, the transition is not violent, as good philosophers will admit. What was man before the invention of words and the knowledge of tongues? An animal of his species, who, with much less native instinct than the others, whose king he then considered himself to be, could not be distinguished from the…
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…
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…
The greatest challenges facing parents stem from their own school experiences. Every adult has been educated in some way, and the methods their teachers used usually shape the values they carry with them and color their perceptions of how education “should be.” These learned values are very powerful and can be seen in…
Not only does background knowledge grow in the brains of our students through their experiences, but the vocabulary words that are stored as a result of such experiences provide avenues to comprehend the curriculum from the text, as well as lecture and discussion. We can look at the work of Piaget (1970), who…
After what he had told, I could scarcely imagine what profounder secrets he was saving for the morrow; but at last it developed that his trip to Yuggoth and beyond—and my own possible participation in it—was to be the next day’s topic. He must have been amused by the start of horror I gave at hearing a cosmic voyage…
The DHA-deprived rats also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates synaptic function in the brain. A closer look at the rats' brain tissue suggested that insulin had lost much of its power to influence the brain cells. "Because insulin can penetrate the blood–brain…
We consider a strategy of straightforward duplication of the activity, and look at the numbers of some of the components. The human brain has up to one hundred billion (10^11) neurons and between one hundred trillion (10^14) and one quadrillion (10^15) synapses. But we have reached a point where for purposes of data…
There was a certain kind of beauty, a prettiness that everyone could see. Big eyes and full lips like a kid’s; smooth, clear skin; symmetrical features; and a thousand other little clues. Somewhere in the backs of their minds, people were always looking for these markers. No one could help seeing them, no matter how…
he most common example used is the hives of social insects, where all individuals work for the common good with little regard for themselves. Although it has been argued that hives lack collective minds (Nicholls 1982) it should be noted that all such species communicate with chemical signals, and at least in the case…
The designers of our species set out to produce a being that might be capable of an order of mentality higher than their own. The only possibility of doing so lay in planning a great increase in brain organisation. But they knew that the brain of an individual human being could not safely be allowed to exceed a…
The metabolic costs of brain development are thought to explain the evolution of humans’ exceptionally slow and protracted childhood growth; however, the costs of the human brain during development are unknown. We used existing PET and MRI data to calculate brain glucose use from birth to adulthood. We find that the…
Executive functions take place in the prefrontal cortex of the brain. I love the term that Stanislas Dehaene uses to describe this part of the brain—a global neuronal workspace. The prefrontal cortex is responsible for the ability to exchange information across the high-level areas of the brain, Dehaene says, so that…
We sought to determine whether reading a novel causes measurable changes in resting-state connectivity of the brain and how long these changes persist. Incorporating a within-subjects design, participants received resting-state functional magnetic resonance imaging scans on 19 consecutive days. First, baseline resting…
when a child is upset, logic often won’t work until we have responded to the right brain’s emotional needs. We call this emotional connection “attunement,” which is how we connect deeply with another person and allow them to “feel felt.” When parent and child are tuned in to each other, they experience a sense of…
A toddler falls and scrapes an elbow. A kindergartner loses a beloved pet. A fifth-grader faces a bully at school. When a child experiences painful, disappointing, or scary moments, it can be overwhelming, with big emotions and bodily sensations flooding the right brain. When this happens, we as parents can help bring…
