A subset of neurons shown here, called PKC delta-expressing cells, located in the brain's central amygdala, drive aversive learning in mice, neuroscientists have demonstrated. A subset of neurons ...

Experiments in mice reveal that personal history, ... It connects the basolateral amygdala, a clump of nerves in the midbrain where emotions are processed, to the prefrontal cortex, ...

Mice taught to link smells with tastes, and later fear, revealed how the amygdala teams up with cortical regions to let the ...

Within 100 milliseconds of stimulating a mouse amygdala, the animal’s neck and jaw muscles tensed up, the researchers observed. When faced with a non-edible object or a live cricket, ...

They focused on two parts of the brain -- the amygdala, which processes emotion, and the dentate gyrus of the hippocampus, where much of a memory's context and detail are stored. Context includes ...

The part of the brain that governs emotions such as fear and anxiety also helps mice hunt. That structure, the amygdala, orchestrates a mouse’s ability to both stalk a cricket and deliver a ...

To take advantage of this division, the researchers took two groups of male mice that had been genetically modified so that neurons in the hippocampus and amygdala would respond to light.

Normally, male mice are slow to warm up, taking 10 to 15 minutes before mounting. ... It found that if scientists manipulated the neurons in a part of the amygdala, ...

Researchers have found that male mice encountering female mice showing signs of illness, the males interacted very little with the females and made no attempts to mate with them as they normally would ...

With a flip of a switch, researchers can make a mouse can shed its anxious, shy demeanor. The scientists can dial mouse anxiety up or down by lighting up a very specific connection between two ...

Mice aren’t men, so it’s not known if this mating mechanism will hold true for humans. But because this circuit lives in an evolutionarily ancient part of the brain, it is likely to be ...
