Scientists have been working on neural speech prostheses, special devices that can help people who have trouble speaking by translating brain activity into speech.

New research findings provide a novel understanding of how the human brain regulates emotions, distinguishing between emotion generation and regulation. By analyzing fMRI studies, researchers identified specific brain regions, including areas of the anterior prefrontal cortex, that are key to emotion regulation.

The sense of smell is highly influenced by the cues from other senses, while the sense of sight and hearing are affected to a much lesser extent, shows a new study in Journal of Neuroscience.

Researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the team’s findings, published in Scientific Reports, suggest that the axons in memory centers of the hippocampus play a role.

Earlier menopause combined with a higher risk of cardiovascular disease is linked to an increased risk of thinking and memory problems later, according to new research.

A noninvasive brain stimulation treatment improved depression and anxiety symptoms among older adults in a new study. The findings, published in the journal Brain Stimulation, suggest the treatment, known as transcranial direct current stimulation, or tDCS, holds promise as a noninvasive, drug-free option to treat depression and anxiety symptoms, which affect 1 in 4 older adults.

A new study explores the influence of personalized music on cognitive arousal and performance.

Finally this week, new research has found human brains are getting larger. Study participants born in the 1970s had 6.6% larger brain volumes and almost 15% larger brain surface area than those born in the 1930s.
