Like a ripple in the water, a parent’s illness can’t help but affect her offspring. Different studies have documented how depression in a new mother clearly affects her interactions with her baby or toddler. Depressed mothers are more withdrawn, less responsive to their infant’s signals. “Their facial expressions and displays of emotion [are] more muted or flat, and their voices [are] monotone,” explains Ruta Nonacs in “A Deeper Shade of Blue.” “They [remain] disengaged and [do] little to support their child’s activities or exploration of the environment.” A mother’s depression also affects grade-schoolers and adolescents. When parents fail to meet the needs of the people under their care, some kids begin to act out, have ...

The study adds to evidence that primal fear responses do not depend on the amygdala - long a favored region of fear researchers - but on an obscure corner of the primeval brain. A group of neuroscientists led by Larry Swanson of the University of Southern California studied the brain activity of rats and mice exposed to cats, or to rival rodents defending their territory. Both experiences activated neurons in the dorsal premammillary nucleus, part of an ancient brain region called the hypothalamus. Swanson's group then made tiny lesions in the same a...

Learning. We at SharpBrains love to learn, and to see others learn. That's why we hope you enjoy this essay by educator Laurie Bartels as much as we do. --- 10 Brain Tips That Help Me Teach…and Learn -- By Laurie Bartels My natural rhythms are in cycle with the school calendar. January 1st takes a back seat to my new year, which gets ushered in with the month of September when there is crispness in the air that gradually shakes off the slower, more relaxed pace of summer. Conveniently, my career in teaching meshes with my natural cyclical year. And as this year draws to a close, I am reenergized by the pace of summer, knowing that anything may pop in to my mind as I engage in activities not directly related to school. But before that happen...

Both authors, J.M. Coates and J. Herbert are from the Dept. of Physiology, Development and Neuroscience at Cambridge University . But J.M.C. is also from the School of business at Cambridge , and his main research interests are summarized by him thusly: “ I have been sampling endogenous steroids from traders on a trading floor in the City to determine the role of both testosterone and cortisol in their decision making and in their performance.

The normal daily diet of an adult male contains about 2000-2400 calories. The ‘calorie restriction’ people limit their diet to about half of that. They may live longer, but are they happier?

We ate and we ate, and drank and drank—I thought we are going to burst. Literally. I hope everybody in our Thanksgiving party (over 30 people) survived intact. Being a doctor, and a worrier, the thoughts of what could go wrong were never quite banished by the pleasures of gluttony. What dangers were going through my mind?The burst stomachHave you ever seen a snake swallowing a whole turkey? You can actually see the poor creature traveling through the long intestines of the tubular glutton. Well, a burst stomach is extremely rare, and happens only in rare conditions where the brain center controlling hunger and satiety is malfunctioning. Normal stomach capacity is about 8 cups, although it can range form 4 to 12, according to Dr....

Hormones control growth, metabolism, reproduction, the fight-or-flight fear response and many other important biological processes. In humans, and all other vertebrates, the chemical signals are produced by specialized brain centers such as the hypothalamus and secreted into the blood stream that distributes them around the body. Researchers from the European Molecular Biology Laboratory (EMBL) now reveal that the hypothalamus and its hormones are not purely vertebrate inventions, but have their evolutionary roots in marine, worm-like ancestors. In this week's issue of the journal Cell they report that hormone-secreting brain centers are much older than expec...

How so? First – your auditory cortex gathers information about the sound. In the meantime your inner clock, sometimes called a circadian rhythm, let’s you know the light is here and it’s time to rise. The Hypothalmus adjusts your system by lowering your levels of the chemical melatonin, which help you to awaken more fully for the day ahead.  Why not work with your brain in these two ways - 1).

The reason for that is that our primitive ancestors, leading a life of hunters/gatherers (or scavengers, as recent research suggests) did not have a steady, predictable supply of food. So our physiology has evolved to store calories when we could get them, in the form of fat. The need was to maximize conservation of energy (or calories), and an elaborate system has evolved in the gut and the brain to accomplish that. This state of affairs served our species well until relatively recently. When the industrial revolution arrived about 200 years ago, farms became more efficient and produced more food, people became more affluent working in factories and offices, being able to afford the cornucopia of food and drink. At the same time wor...

Kolata reviewed work suggesting that genes are involved in obesity, with the implication that a fight to lose and maintain a lower weight is not only excruciating, it is practically futile.That simply didn’t sound right. At least 10 genes have been discovered thus far that are involved in obesity and diabetes; more are bound to be discovered. We also know that the US population is fast approaching the 50% mark of overweight (BMI 25-29.99) or obese (BMI > 30). These genes presumably are not recent mutations. Why is it then, that only relatively recently did these genes express t...

The institutions involved in this research (U. Iowa Dept. of Neurology, Harvard U. Dept. of Psychology, and the Brain and Creativity Institute at the U. Southern California) reflect the multi-disciplinary approach required for such a study. Where in the brain is Morality? Our brain is organized in layers, somewhat like an onion. The deepest layer, like the brain stem and the structures around it, is the most ancient, or primitive, from an evolutionary point of view. These structures co...
