Researchers have created a new cortical surface template called 'OpenNeuro Average,' or 'onavg' for short, which provides greater accuracy and efficiency in analyzing neuroimaging data.
Researchers have created a new cortical surface template called 'OpenNeuro Average,' or 'onavg' for short, which provides greater accuracy and efficiency in analyzing neuroimaging data.
Each brain has a different shape. To analyze neuroimaging data of multiple individuals, researchers need to register the data to the same brain template, which enables identifying the same anatomical location on different brains, even though brains have different shapes. These locations are known as"vertices."
The team built the template based on the cortical anatomy of 1,031 brains from 30 datasets in OpenNeuro, a free and open-source platform for sharing neuroimaging data. According to the co-authors, it is also the first cortical surface template based on the geometric shape of the brain. He says their cortical surface template could be used for studies on vision, hearing, language, and individual differences, as well as on disorders such as autism and neurodegenerative diseases like Alzheimer's and Parkinson's.

Researchers pinpoint brain cells that delay first bite of foodDo you grab a fork and take a first bite of cake, or say no and walk away? Our motivation to eat is driven by a complex web of cells in the brain that use signals from within the body, as well as sensory information about the food in front of us, to determine our behaviors.

Researchers identify brain region involved in oxycodone relapseEven years after they have recovered, a person who once struggled with alcohol or opioid addiction can relapse--and that relapse is more likely to occur during particularly stressful times. Now, scientists have identified an area of the brain that plays a key role in stress-induced oxycodone relapse.

Researchers uncover brain region's role in hearing and learningThe human brain is remarkably adept at adjusting what we hear based on contexts, like our current environment or priorities, but it's still unknown how exactly the brain helps us detect, filter and react to sounds. Now, biologists are a step closer to solving that mystery.
