Overturning a 70-year old paradigm which said that the major activity occurs in synapses between neurons, these scientists claim that the dendrites are where the action is.
---Highly-activated dendrites grow stronger, they say, and less active dendrites grow weaker.
The (skeleton) structure of the brain is like a road map consisting of many narrow streets (i.e., weak links), and a small fraction of highways each containing thousands of lanes (i.e., very strong links).
Such a diverse road map could either be
---a spontaneous outcome of a random brain activity,
---or alternatively could be directed by a meaningful learning activity, where the “highways” direct the information flow in the brain.

for determining if unresponsive patients, assumed ‘brain dead’ or in a coma, might still have a “who” inside able to consciously choose to respond in some way other than voice, eye blinks or limb movements. “New research suggests that an electrophysiologic screening tool can identify people with severe brain injuries who are likely to be covertly conscious.” This implies that a person’s soul (whatever one wishes to call an immaterial, personal being) has control over the body and the brain.
“You can’t have a memory of an event without having some sort of experience of how long it took place. It’s important to better understand how the brain processes the entire timeline of an experience, and how that’s being represented in long-term memories,” he says.

The human brain works backwards to retrieve memories (Medical Xpress). Researchers at the Center for Human Brain Health found some things about how we retrieve memories.
---They found that, when retrieving information about a visual
object, the brain focuses first on the core meaning—recovering the ‘gist’ – and only afterwards recalls more specific details.
---This is in sharp contrast to how the brain processes images when it first encounters them. When we initially see a complex object, it’s the visual details—patterns and colors—that we perceive first. Abstract, meaningful information that tells us the nature of the object we’re looking at whether it’s a dog, a guitar, or a cup, for example, comes later.

The brain’s capabilities are awesome and intriguing, but they are like tools and servants at our disposal. We have the experience of managing our brains and commanding it to do things for us.
For example, try to remember a name. Concentrate on it for awhile, then turn your attention elsewhere. Many times, the answer will pop up shortly thereafter, as if it took time to do a keyword search in your brain’s storage. The brain is not the soul, however, and our souls are responsible for how we use these marvelous gifts our Creator gave us."

And the LORD God formed man of the dust of the ground,
and breathed into his nostrils the breath of life;
and man became a living soul.
