Can we regenerate brain-matter?

Can we regenerate brain-matter?

Nerve cells are the most commonly known cells in the brain. Therefore it would be logical to suggest that nerve cells have the majority in the human brain. Yet this not completely right. Star-shaped glial cells, the so called “astroglia”. Glial means glue. As befits their name, until now these cells have been regarded merely […]

How neural activity contains coded information

How neural activity contains coded information

The electrically excitable cells in the nervous system that transport information, also called neurons, can produce short binary, all-or-nothing reaction-spikes of voltage, which travel as a pulse along the specialized extensions (axons) which causes the release of neurotransmitters. The spikes contain information about the world around the subject: what do I see, smell, hear, taste, […]

Rocket propelled bionic arm

Rocket propelled bionic arm

When you are forced to use a prosthetic device, it usually is quite cumbersome and has disadvantages. But, with this is going to change with the help of rockets. The new prototype rocket-powered mechanical arm can lift about 9 to 12 kilograms – three to four times more than current commercial prosthetic arms – and […]

Sugar-sensitive neurons possibly causing diabetes

Sugar-sensitive neurons possibly causing diabetes

Some neurons, which are sensitive for the amount of glucose in blood, appears to play an important roll in the cause of Diabetes mellitus type 2 (adult-onset diabetes). These neurons become active when more glucose appears in the blood, which causes an increase in sugar-uptake. If these neurons are made insensitive, artificially, for glucose, diabetes […]

Meth, the world’s most dangerous drug

Meth, the world’s most dangerous drug

Meth, crystal meth, speed, ice, crank, tweek/tweak, glass, uppers, yaba, shabu shabu. Just some synonyms for the drug methamphetamine. After seeing the documentary on National Geographic about meth, I got interested in the way the drug works and effects the body. The results of use are, although the process is slow, disasterious, both on inside […]
