Computer model helps make sense of human memory
Researchers have created an artificial network to simulate the brain, demonstrating that tinkering with inhibitory circuits leads to extended memory.

Long-term study data shows DBS is effective treatment for most severe form of depression
Deep brain stimulation (DBS) of an area in the brain called the subcallosal cingulate (SCC) provides a robust antidepressant effect that is sustained over a long period of time in patients with treatment-resistant depression — the most severely depressed patients who have not responded to other treatments.

A team of biomedical engineers are developing a therapy which shows early indications it can protect neurons and stimulate the regrowth of blood vessels in damaged tissue.
Read moreMounting brain organoid research reignites ethical debate
As research involving the transplantation of human 'mini-brains' — known as brain organoids — into animals to study disease continues to expand, so do the ethical debates around the practice. A new article seeks to clarify the abilities of brain organoids and suggests an ethical framework that better defines and contextualizes these organoids and establishes thresholds for their use.
Read moreWhy the language-ready brain is so complex
Scientists argue for a new model of language, involving the interaction of multiple brain networks. This model is much more complex than the classical neurobiological model of language, which was largely based on single-word processing.
Read morePesticides likely caused 'Havana syndrome' that affected Cuba-based diplomats
The study details the nature of the injury, specifies the brain regions involved, including the blood-brain barrier and suggests a possible cause in the form of 'cholinesterase inhibitors,' with 'organophosphorus insecticides' being a likely source. Cholinesterase (ChE) is one of the key enzymes required for the proper functioning of the nervous systems of humans, invertebrates and insects.

Pupils do better in spelling tests if teachers reward them for team — rather than individual — performance, according to new findings.
Read moreDrops in income may not only hurt the wallet, they may harm the brain
Young adults who experience annual income drops of 25% or more may be more at risk of having thinking problems and reduced brain health in middle age, according to a new study.
Read moreExploring the brain in a new way: Researcher records neurons to understand cognition
Whether we're searching for Waldo or our keys in a room of clutter, we tap into a part of the frontal region of the brain when performing visual, goal-related tasks. Some of us do it well, whereas for others it's a bit challenging. One researcher set out to investigate why, and what specifically this part of the brain, called the pre-supplementary motor area, does during searching.
Read moreNeuroimaging reveals hidden communication between brain layers during reading
Language involves many different regions of the brain. Researchers have discovered previously hidden connections between brain layers during reading, in a neuroimaging study. The team used laminar Functional Magnetic Resonance Imaging (lfMRI) to investigate what happens when people read Dutch words like ''zalm'' (salmon) compared to pseudowords (''rorf''), revealing top-down influences on deep brain layers for the first time.
