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…

How attention orchestrates groups of nerve cells to enrich the brain’s symphony

A new study on rhesus monkeys shows how our brain processes complex signals.

Past memory cues help people juggle numerous pieces of information

A study using EEG suggests that the brain has several different mechanisms to help boost memory performance following a sudden change in the priority or relevance of a given piece of information. Past memory cues can have different effects on neural re…

Noninvasive brain stimulation may soon reach more aphasia patients

Researchers tested the use of transcranial direct current stimulation in stroke patients with aphasia. Their results pave the way for the creation of a large clinical trial to test the new treatment in a number of patients who have lost some or all of …

New CDC guidelines detail treatment of pediatric mild traumatic brain injury

New evidence-based guidelines put forward recommendations for a broad range of health care providers responsible for detection and management of pediatric mild traumatic brain injury, most of which are concussions.
