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.

have shown that both calorie restriction and intermittent fasting along with vitamin and mineral intake, increase resistance to disease, extend lifespan, and stimulate production of neurons from stem cells.

Physical exercise may also have beneficial effects on neuron regeneration by stimulating regeneration of brain and muscle cells via activation of stress proteins and the production of growth factors. But again, additional research suggests that not all exercise is equal. Interestingly, some researchers found that exercise considered drudgery was not beneficial in neuronal regeneration, but physical activity that was engaged in purely for fun, even if equal time was spent and equal calories were burned, resulted in neuronal regeneration.

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.
Memories may be stored on your DNA - 26 November 2008 - New Scientist - 1 views

To remember a particular event, a specific sequence of neurons must fire at just the right time. For this to happen, neurons must be connected in a certain way by chemical junctions called synapses. But how they last over decades, given that proteins in the brain, including those that form synapses, are destroyed and replaced constantly, is a mystery.

Many genes are already coated with methyl groups. When a cell divides, this "cellular memory" is passed on and tells the new cell what type it is - a kidney cell, for example. Miller and Sweatt argue that in neurons, methyl groups also help to control the exact pattern of protein expression needed to maintain the synapses that make up memories.

Dream Recorder: New Technology Could Display Your Dreams on Screen - 3 views

In a nutshell, the device converts electrical signals sent to the visual cortex into images that can be viewed on a computer screen. In their experiment, they showed test subjects the six letters in the word neuron and succeeded in reconstructing the word on screen by measuring their brain activity. As the technology progresses, it could be possible to "see" what people are thinking, what they dream about and record it for posterity. What do you think? Would that be awesome or scary as hell? All I know is that image weirds me out. [Yahoo Image via Pink Tentacle Thanks Roger!]
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.

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.

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.
