The Neural Circuitry of Parenting Behavior

News   Apr 12, 2018 | Original Story from HHMI

Neuroscientists Map the Neural Circuits That Underlie Parenting Behavior

In the mouse brain, a cluster of neurons (red) within the medial preoptic area acts as a parenting control hub, orchestrating behaviors like grooming and interacting with pups. Some of these neurons (blue) reach out to a motor command region called the periaqueductal gray. Credit: Dulac Lab/HHMI/Harvard



Ambidextrous Squirrels Perform Best in Learning Tasks


Squirrels that strongly favor their left or right side are less good at learning, new research suggests. The University of Exeter study found that grey squirrels which strongly favored a side did less well on a learning task. They had to learn to use a paw, rather than their mouth, to get nuts.


How Infants Decide When To Try


According to a new study that has implications for how people learn, infants do not try things at random or simply mimic what they see adults doing. Instead, they combine information from their own firsthand experience and the experiences of other people to decide whether to persist in trying to solve a problem.


Progression of Eye and Cardiac Disease Halted by Food Supplement


UNIGE researchers have discovered a new gene that causes blindness and
cardiomyopathy. They have also managed to halt the progression of eye disease and treat cardiac disease by administering a food supplement.
