A constant blood supply to the heart is so important to keep well the performance of your heart. And the coronary arteries and veins are so vital to provide a constant blood supply. One of the most frequently asked questions is "What are causes of heart disease?"

Brain Awareness Week is an inspirational global campaign that unites those who share an interest in elevating public awareness about the progress and benefits of brain and nervous system research.
Brain Awareness Week runs from March 12th through 18th and is a time when scientists, researchers, and educators share the latest information in the area of neuroscience.
Brain health is vital to our mental and physical well-being, so go out and celebrate your brain. I'm going to attempt some super difficult crosswords puzzles. Make sure I eat green leafy vegetables, maybe some extra fish this week - and take my brain for a longer walk than usual.
What will you do this week to maximize your brain health?
Can heart disease be prevented, if so how to prevent it? As well we know that it is one of popular causes of death in this modern living. It is divided into several types, and each type has different symptoms. But chest pain (more typically in men) and shortness of breath are the common symptoms of all types of heart disease.
One of great ideas to prevent heart disease is by clearly knowing
If you seriously want to lower your risk of developing heart disease, you should also clearly understand about what are risk factors for heart disease. Generally, there are two major categories of heart disease risk factors; uncontrollable and controllable risk factors.

Heart attack is one of the most popular serious diseases in this modern living. It can attack anyone, either men or women. And what are heart attack symptoms in men? Let’s explore more the answer in this article. Read also about heart attack signs in women!
In fact, (according to CDC) heart attack is the top cause of death for men in the U.S! About 427,000 men in the US were death due to
We have previously discussed the electrical properties of neurons. Much like the sodium ion (Na+) and the potassium ion (K+), the calcium ion (Ca2+) can flow into and out of the cell to modulate its electrical activity.
Calcium has an even bigger role, however. When a burst of activity in a particular neuron causes calcium channels to open, the calcium ions rush in and bind to all sorts of molecules inside the cell. These molecules help adjust the connection between two neurons by helping to strengthen or weaken the synapse between them.
Because calcium easily binds to many molecules, and because it flows into the cell when the cell is activated, dyes which bind to calcium have made it possible for scientist (and you) to 'watch' neurons fire:
Amazing, right? When the neurons are activated, the calcium rushes in and binds to the dye and causes the cell to light up.
If you noticed, it's not just the main middle part of the cell (the soma) that lights up, the dendrites light up too. If you watch very closely you can even determine the direction of the signal. Sometimes it is going down the dendrite to the soma, and sometimes it is going up from the soma out through the dendrite. Being able to see the location of the calcium signal is more specific that just seeing (or hearing) spikes from neural activity (which is a summary of what the cell is doing as a whole, but doesn't differentiate between parts of a neuron).
A recent review by Grienberger and Konnerth highlights some of the even more amazing advances to calcium imaging. They explain how, using a light-weight teeny-tiny head-fixed microscope, scientists can now image the activity of neurons inside the brain of a living, moving mouse.
This is a huge advance because now scientists can see not only that a specific cell is firing when something happens, but can actually watch the activity of different dendrites on a single neuron when that thing happens.
One of the limitations to using calcium imaging to watch neurons in the intact brain is that light doesn't travel through the brain that well. So far only the neurons close to the surface of the brain are being imaged.

It is undeniable that one of the serious diseases that can kill a lot of people in this modern living is heart disease. Even this disease kills more women /year than any other diseases. Men are more likely to show up
