Recurring memory traces boost long-lasting memories
While the human brain is in a resting state, patterns of neuronal activity which are associated to specific memories may spontaneously reappear. Such recurrences contribute to memory consolidation—i.e. to the stabilization ...

Cortical cause of anxiety states
Fear, at the right level, can increase alertness and protect against dangers. Disproportionate fear, on the other hand, can disrupt the sensory perception, be disabling, reduce happiness and therefore become a danger in itself. ...

Locusts reveal how neurons distinguish multiple odors
(Medical Xpress)—Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such ...

New theory explains how critical periods are triggered during development of the nervous system
Experiments performed in the 1960s showed that rearing young animals with one eye closed dramatically altered brain development such that the parts of the visual cortex that would normally process information from the closed ...

Observing brain activity during learning errors
(Medical Xpress)—A major goal in neuroscience is to be able to use magnetic resonance images of brain activity to identify how a person learns. Researchers from ETH and the University of Zurich have taken an important step ...

When neurons have less to say, they speak up
The brain is an extremely adaptable organ – but it is also quite conservative. That's in short, what scientists from the Max Planck Institute of Neurobiology in Martinsried and their colleagues from the Friedrich Miescher ...

Decoding sound's source: Researchers unravel part of the mystery
As Baby Boomers age, many experience difficulty in hearing and understanding conversations in noisy environments such as restaurants. People who are hearing-impaired and who wear hearing aids or cochlear implants are even ...
