Artificial intelligence singles out neurons faster than a human can

Biomedical engineers at Duke University have developed an automated process that can trace the shapes of active neurons as accurately as human researchers can, but in a fraction of the time. This new technique, based on using artificial intelligence to interpret video images, addresses a critical roadblock in neuron analysis, allowing researchers to rapidly gather … Read more

Anesthesia sends neurons down the wrong path in unborn rat babies

Study: Anesthesia disrupts the ‘precisely choreographed’ migration neurons make in developing brains. Preventing them from ‘arriving at their proper and predetermined’ locations can have profound impact on brain development. Credit: Dr. Vicko Gluncic, MD, PhD While there has long been discussion whether exposure to anesthesia affects brain development, new Rush University Medical Center research published … Read more

Damaged mitochondria use ‘eat me’ signals for mitophagy

When mitochondria become damaged, they avoid causing further problems by signaling cellular proteins to degrade them. In a paper publishing April 11, 2019, in the journal Developmental Cell, scientists in Norway report that they have discovered how the cells trigger this process, which is called mitophagy. In cells with broken mitochondria, two proteins–NIPSNAP 1 and … Read more

‘Mindreading’ neurons simulate decisions of social partners

Credit: CC0 Public Domain Scientists have identified special types of brain cells that may allow us to simulate the decision-making processes of others, thereby reconstructing their state of mind and predicting their intentions. Dysfunction in these ‘simulation neurons’ may help explain difficulties with social interactions in conditions such as autism and social anxiety. Researchers at … Read more

Study shows thousands of neurons becoming active during thirst and quench cycle

Credit: CC0 Public Domain A team of researchers with Stanford University and Howard Hughes Medical Institute has used a new tool to record activation of thousands of neurons due to thirst and quenching in a mouse brain. In their paper published in the journal Science, the group describes their study of the mouse brain during … Read more

Scientists locate brain circuit that curbs overeating

The brain has complex circuitry that locks appetite to memories of finding and enjoying food. This drives the feeding behaviors necessary for survival. New research reveals that the circuits include one mechanism that does the opposite: curbing the compulsion to eat in response to food. ‘People may be able to learn to change their relationship … Read more

Harvard: Neuronlike brain implants may help treat disease, mental illness

Sensors go undercover to outsmart the brain Charles Lieber and his colleagues published a paper on neural probes that are less detectable by the human brain and may be more effective in treatment. Rose Lincoln/Harvard file photo Devices used in mice offer a more accurate way to study the brain, potential treatment for disease, damage, … Read more
