-
Granger's original objective was to see if links could be established that allowed economists to use current economic data to forecast changes in the economy in the near future. But first author Steven L. Bressler, Ph.D., professor of psychology at Florida Atlantic University, suspected the technique might help reveal if one brain area was passing data to or influencing another brain area.
Study provides new insights about brain organization - 0 views

"One theory is that individual senses have separate areas of the brain dedicated to them," said Mark Wallace, Ph.D., the study's lead investigator. "In this view, information is processed initially on a sense-by-sense basis and doesn't come together until much later. However, this view has recently been challenged by studies showing that processing in the visual area of the brain, for example, can be influenced by hearing and touch."

Only recently have scientists been able to learn how the neural network of the brain forms. Beginning in the womb and throughout life this vast network continues to expand, adapt, and learn.

Some specific types of sensory stimuli and activities, especially those that involve non-routine actions and thoughts, produce more of those chemicals that encourage growth of new dendrites and neurons in the brain. These are generally non-routine activities. Routines become so automatic that actions are done largely unconsciously (ever get up in the morning and walk to the bathroom before you're really conscious?). Such automated or unconscious actions require less activity in the brain, and exercise it less.
Not Exactly Rocket Science : Taking the new out of neurons - 0 views

The situation is much the same in primates and rodents, where new neurons only appear in the hippocampus and olfactory bulb. In contrast, fish, reptiles and birds renew the neurons throughout their entire network and throughout their entire lives.
Technology Review: Detecting Brain Chemicals - 0 views

Sampling the brain: A device by the Mayo Clinic can analyze and detect neurotransmitters locally in the brain. Blue wires link an external monitor (circuit board) to gray connectors, which are in turn linked to neurotransmitter-sensing electrodes (not shown). The device is battery operated (the battery is shown connected to the circuit board) and can transmit the neurochemical information from the electrodes to a remote station for analysis.
Looking Inside the Human Brain - 0 views

What's really going on inside your head when you make a decision, make a mistake, or have a few drinks? In this segment, Ira and guests talk about new research involving the field of functional magnetic resonance imaging, or fMRI. The technique allows researchers to monitor the blood flow through parts of the brain as it responds to stimuli, allowing researchers to monitor which parts of the brain are active and which are resting. Though the technique is being eagerly explored in a variety of fields, fMRI has received criticism from some brain experts as being the modern-day equivalent of phrenology. We'll hear about the technique, and what it can tell researchers about the inner workings of the human brain.

The 'satellite navigation' in our brains - 0 views
-
"The hippocampus is crucial for navigation and we use it like a 'sat nav'," says Dr Spiers from the Institute of Behavioural Neuroscience at UCL. "London taxi drivers, who have to know their way around hundreds of thousands of winding streets, have the most refined and powerful innate sat navs, strengthened over years of experience."

Science News / Do Subatomic Particles Have Free Will? - 0 views
-
Human free will might seem like the squishiest of philosophical subjects, way beyond the realm of mathematical demonstration. But two highly regarded Princeton mathematicians, John Conway and Simon Kochen, claim to have proven that if humans have even the tiniest amount of free will, then atoms themselves must also behave unpredictably.
-
“If the atoms never swerve so as to originate some new movement that will snap the bonds of fate, the everlasting sequence of cause and effect—what is the source of the free will possessed by living things throughout the earth?”—Titus Lucretius Carus, Roman philosopher and poet, 99–55 BC.

However, contact between nerve cells is also constantly being set up and dismantled in adults. It is this continuous restructuring of the brain that allows us to learn and to forget.
-
In reality, it should actually be consuming much more energy. This is because both young and adult nerve cells allow many hundreds of cell extensions to grow towards their neighbours.

Free Will vs. the Programmed Brain: Scientific American - 0 views
-
-
In this light, it’s not surprising that people behave less morally as they become skeptical of free will. Further, the Vohs and Schooler result fits with the idea that people will behave less responsibly if they regard their actions as beyond their control. If I think that there’s no point in trying to be good, then I’m less likely to try.
Cooking and Cognition: How Humans Got So Smart - 0 views

For a long time, we were pretty dumb. Humans did little but make "the same very boring stone tools for almost 2 million years," he said. Then, only about 150,000 years ago, a different type of spurt happened — our big brains suddenly got smart. We started innovating. We tried different materials, such as bone, and invented many new tools, including needles for beadwork. Responding to, presumably, our first abstract thoughts, we started creating art and maybe even religion.

Resilience is the ability to successfully manage life and adapt to stressful events. Resilience is developed in childhood, when there are loving people available to help during difficult times, but if a child feels alone, resilience is not developed just because challenging things are happening.

Due to recent brain research on neuroplasticity, we know that brains are growing and creating neural pathways during childhood and through adolescence. What's new in this book is the focus on a repetitive practice that strengthens these neural pathways and teaches young people concrete skills to calm themselves and focus their attention.
-
The interesting part of the connection between stress and learning is that the prefrontal cortex of the brain is the area for paying attention, calming, and focusing as well as the area for short- and long-term memory.
