The word “synapse” turns 120 years old in 2017.
This is how brain cells can talk without ever touching. The synapse is a gap between two nerve cells. The cells pass messages across the space. Synapses can be chemical or electrical. In a chemical synapse, one cell releases a small burst of chemicals — called neurotransmitters — into the space. This gap is between 20 and 40 nanometers wide (about 10 to 20 times the thickness of a strand of DNA). The chemicals drift across the gap and bind to molecules on the other side, passing the message from cell to cell.
Electrical synapses are also called gap junctions, and they are much smaller — only 3.5 nanometers wide or so. That’s about twice as wide as a DNA strand. Molecules called channels link the two cells. Electrical signals pass through the channels, taking the message from one cell to the next.
The word “synapse” turns 120 years old in 2017. In 1897, the British scientist Charles Sherrington came up with the idea. But it was Arthur Verrall — a professor of classical literature — who gave the synapse its name that same year.

Perceptions: Share and Augment Your World

Love me or hate me, both are in my favor. If you love me, I will always be in your heart. If you hate me, I will always be in your mind. William Shakespeare
This is where our behavior, relationships and trust values come into play in our lives. Do we Invite In or do we Repel the very Ideals we Seek? http://wp.me/p2RQIw-1aa

It’s ‘digital heroin’: How screens turn kids into psychotic junkies | New York Post

'... Many parents intuitively understand that ubiquitous glowing screens are having a negative effect on kids. We see the aggressive temper tantrums when the devices are taken away and the wandering attention spans when children are not perpetually stimulated by their hyper-arousing devices. Worse, we see children who become bored, apathetic, uninteresting and uninterested when not plugged in.

But it’s even worse than we think.

We now know that those iPads, smartphones and Xboxes are a form of digital drug. Recent brain imaging research is showing that they affect the brain’s frontal cortex — which controls executive functioning, including impulse control — in exactly the same way that cocaine does. Technology is so hyper-arousing that it raises dopamine levels — the feel-good neurotransmitter most involved in the addiction dynamic — as much as sex.

MicroRNA Treatment Restores Myelin and Limb Function in Multiple Sclerosis: Mouse Study

Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA.

The research is in Developmental Cell. (full access paywall)
