Computer model helps make sense of human memory

Brains are a mazy network of overlapping circuits—some pathways encourage activity while others suppress it. While earlier studies focused more on excitatory circuits, inhibitory circuits are now understood to play an equally ...

Learning transistor mimics the brain

A new transistor based on organic materials has been developed by scientists at Linköping University. It has the ability to learn, and is equipped with both short-term and long-term memory. The work is a major step on the ...

Timings and behaviour influence worm's response to force

How worms respond to signals such as taps or touches depends on details of the signal, including whether it increases or decreases, and on what the animal is doing at the time, says Andrew Leifer and his team of researchers ...

Discovery of the neural circuit for fear conditioning of fish

Animals are often noted sensing signs of danger and reacting. A simple form of this phenomenon is called fear conditioning, which is a type of learning commonly seen in every animal. By manipulating the activity of specific ...

Scientists discover plant 'brain' controlling seed development

A new study by scientists at the University of Birmingham has revealed a group of cells that function as a 'brain' for plant embryos, capable of assessing environmental conditions and dictating when seeds will germinate.
