How the brain structure that produces norepinephrine also helps control visual attention
The locus coeruleus (LC) is a small region of the brainstem that produces norepinephrine, a chemical with powerful effects on arousal and wakefulness which plays an important role in the body's response to stress or panic. ...

Researcher discusses mechanism behind a birth defect affecting brain size
Nonsense-mediated RNA decay, or NMD, is an evolutionarily conserved molecular mechanism in which potentially defective messenger RNAs, or mRNAs (genetic material that instructs the body on how to make proteins), are degraded. ...

Exploring the origins of excitatory and inhibitory neuronal tuning in the postsubiculum
Brain cells can be broadly divided into two categories: inhibitory and excitatory neurons. Excitatory neurons are cells that support the generation of electrical impulses in postsynaptic neurons, thus prompting the activation ...
Neuroscientists discover two specific brain differences linked to how brains respond during tasks
A new study by neuroscientists at Florida State University has revealed brain differences that may explain why humans demonstrate a variety of cognitive abilities and behaviors.

Neuroscientists find integrity of white brain matter in superagers does not deteriorate, explains sharp memory
A team of neuroscientists from Universidad Politécnica de Madrid and Queen Sofia Foundation Alzheimer Center, both in Spain, has found that so-called superagers maintain memory as they grow older because they do not experience ...
What goal-directed learning is and why it's important for adolescents to learn from their actions
Imagine you're at a carnival and want to win a big stuffed toy. You play different games and, if successful, collect tickets. But it's not the tickets you care about, it's the big toy they'll buy.
