Decision Making And Perception Of Risk Affected By Hunger
2013-06-25 12:39:40

Max-Planck-Gesellschaft Different neural circuits process environmental signals depending on the state of satiation Hungry people are often difficult to deal with. A good meal can affect more than our mood, it can also influence our willingness to take risks. This phenomenon is also apparent across a very diverse range of species in the animal kingdom. Experiments conducted on the fruit fly, Drosophila, by scientists at the Max Planck Institute of Neurobiology in Martinsried have shown...

Dopamine Has Many Messages
2012-07-18 14:59:38

In the insect brain, dopamine-releasing nerve cells are crucial to the formation of both punished and rewarded memories Children quickly learn to avoid negative situations and seek positive ones. But humans are not the only species capable of remembering positive and negative events; even the small brain of a fruit fly has this capacity. Dopamine-containing nerve cells connected with the mushroom body of the fly brain play a role here. Scientists from the Max Planck Institute of...

Beneficial intestinal bacteria can activate immune cells and trigger the overreaction of the immune system Multiple sclerosis is caused by a combination of genetic and environmental factors. For a long time, pathogens were believed to be such external influences. According to scientists from the Max Planck Institute of Neurobiology in Martinsried, however, it is apparently not  harmful bacteria that trigger multiple sclerosis, but beneficial ones — specifically, the natural...

Excitation and inhibition remain balanced, even when the brain undergoes reorganization Every second, the brain's nerve cells exchange many billions of synaptic impulses. Two kinds of synapses ensure that this flow of data is regulated: Excitatory synapses relay information from one cell to the next, while inhibitory synapses restrict the flow of information. Scientists at the Max Planck Institute of Neurobiology in Martinsried could now show, in cooperation with colleagues from the Ruhr...

Neurobiologists have determined the number of circuits needed to see movements Surely, everybody knows this phenomenon: an animal doesn't stand out against its background and becomes visible to us only when it moves. The reason behind this is that we depend strongly on our eyesight for navigation, and the perception of motion is particularly well developed. But what exactly happens in the brain during this process? How must the nerve cells be interconnected for movements to be recognized as...

The human brain consists of approximately one hundred billion nerve cells. Each of these cells needs to connect to specific other cells during the brain's development in order to form a fully functional organism. Yet how does a nerve cell know where it should grow and which cells to contact? Scientists of the Max Planck Institute of Neurobiology in Martinsried have now shown that growing nerve cells realize when they've reached their target area in the fly brain thanks to the interaction of...

Taxol stabilizes growing nerve cells and reduces the barrier-function of scar tissue After a spinal cord injury a number of factors impede the regeneration of nerve cells. Two of the most important of these factors are the destabilization of the cytoskeleton and the development of scar tissue. While the former prevents regrowth of cells, the latter creates a barrier for severed nerve cells. Scientists of the Max Planck Institute of Neurobiology in Martinsried and their colleagues from the...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
