Hard-wiring the fruit fly's visual system
... brain is their size and the number of neurons and connections
that need to be made. A possible explanation for the findings is that the fruit fly has many fewer neurons than vertebrates, and the system can therefore just rely on the genetic components in flies," said Bellen. "In vertebrates, complexity is ad...

Animals resistant to drunken behavior offer clues to alcoholism's roots
...eover, such flexibility, or "plasticity," of nerve connections
in the brain represents the cellular basis for learning and memory. "A growing body of evidence suggests that addiction is, in essence, a maladaptive form of learning," Heberlein added. Alcoholism affects approximately 300 million people worldwi...
Most important actors in the growth process of neurons identified
...e diseases, it is important that we understand how connections
are established between neurons. Neurons have a number of long thin offshoots - called axons - that conduct electrical impulses. These primary elements of information transfer in the nervous system can sometimes be more than a meter long. The axon...
Temperament linked to onset of cancer and early death in female rats

between personality and cancer development, the team suggests. The links between behavior traits and cancer in rats are striking, the scholars found. "This is the first evidence that infant temperament among rats predicts the time at which these t...
Researchers add to understanding of how brain cells communicate
...Johnson. Memories are formed by strengthening the connections
between brain cells, known as synapses. If you touch a hot stove, the pain signal from your hand and the visual signal from your eyes reach the brain at about the same time, forging a memory. Specifically, memory requires the coordinated activation o...
