Study identifies a population of neurons in an area of the midbrain, called the red nucleus, that alter when fine motor skills are learned. The more an action is practiced, the stronger the connections between these neurons become.
Neurons in the motor cortex of rats fall into two categories, those that are externally focused and relay information to other parts of the body, and those that are internally focused. When inhibition is increased, the externally focused neurons switch to internally focused cells.

A minimally invasive brain implant is to be tested on humans for the first time. The device, named Stentrode, will be placed in blood vessels in the motor cortex, and researchers believe it will help improve movement and speech for those with a range of neurological disorders.
A new mouse study reveals a brain circuit that may enable high speed back and forth conversation. The findings could help shed new light on the causes of speech disorders.
An international team of researchers have compiled the largest dataset to date that details differences between healthy brains and those with Alzheimer's disease. The researchers have released the data online and is free to use.
Researchers report on how the brain is spurred into action by hearing certain words. They propose a new simulation theory that perceiving words can drive brain systems into states almost identical to what would be evoked by directly experiencing what the word describes.
Researchers report modern humans who carry particular Neanderthal DNA fragments have slightly less rounded heads. The findings shed light on the evolution of modern brain shape and function.
Researchers report the brain controls speech production in a similar manner to how it controls the production of arm and hand movements. The findings could help to build better speech decoders for BMI, helping those who are unable to speak to find their voice.
