This is how the brain forgets on purpose

Researchers have analysed what happens in the brain when humans want to voluntarily forget something. They identified two areas of the brain — the prefrontal cortex and the hippocampus — whose activity patterns are characteristic for the process of f…

Smiling doesn’t necessarily mean you’re happy

Smiling does not necessarily indicate that we are happy, according to new research.

‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity

Ever wonder why some people seem to feel less pain than others? A study may have found one of the answers — mindfulness.

Bravery cells found in the hippocampus

Why do some people comfortably walk between skyscrapers on a high-wire or raft the Niagara Falls in a wooden barrel whereas others freeze on the mere thought of climbing off escalators in a shopping mall? In a new study, scientists have found that a ce…

Are dementia symptoms worse in winter?

A new study investigating seasonal variation in cognitive ability concludes that more people reach the threshold for a dementia diagnosis in winter.

Stress wracks worm nerves, leaving lasting memories

In a recent study, scientists stunted the puberty of male worms by starving them before they underwent sexual maturation. The researchers suggested that stress from starvation even days before sexual maturation prevented normal changes in the wiring pa…

Building a better brain-in-a-dish, faster and cheaper

Researchers report on the development of a new protocol for creating human cortical organoids — mini-brains derived directly from primary cells that can be used to better explore and understand the real thing.

Novel epigenetic control found for critical brain proteins in memory strengthening

Researchers have found a mechanism that links epigenetic changes to translational control during fear memory reconsolidation. They report that several particular epigenetic changes in the hippocampus of the rat brain control downstream regulation of tr…

Novel system to track brain chemicals

Researchers have developed a novel method for tracking the activity of small molecules in the brain, including the neurotransmitters serotonin and dopamine. Pairing tiny artificial receptors with semiconductor devices that are able to function in livin…

Properties of stem cells that determine cell fate identified

Researchers have identified intrinsic cell properties that influence the fate of neural stem cells, affecting what type of brain cell they will form: neurons, astrocytes, or oligodendrocytes. This discovery could give scientists a new way to predict or…
