Mammal Brains May Use Same Circuits to Control Tongue, Limbs

Thursday, 27 May, 2021 - 07:30 A paralysed mouse is removed from its enclosure on Thursday in a lab at Ruhr University, Germany. Photo: Reuters London - Asharq Al-Awsat Much remains unknown about how the brain controls the tongue, given how its quick motions are difficult to track. Now, experiments show that the brain circuits in mice that help the tongue lick water may be the same ones that help primates reach out to grasp objects, scientists report in the journal Nature. Using high-speed video, neuroscientist Tejapratap Bollu and colleagues recorded the sides and bottoms of mouse tongues as the rodents drank from a waterspout.

Mice licking could reveal mysteries of human brain

Date Time Mice licking could reveal mysteries of human brain Every time we reach for a cup, our brains must assess our hands’ current position in relation to the mug and then command muscles to make the proper adjustments to successfully grab the handle. The neuroscience of reaching for something and making on-the-spot adjustments has been studied for a century in monkeys. But now, for the first time, Cornell researchers have developed a technique for studying such motor control in mice – by focusing on a mouse’s tongue when it licks a water spout. The technique incorporates high-speed cameras and machine learning in a tractable experimental setup that opens the door for revealing mysteries of how the motor cortex works, understanding the neural basis of related disorders like Parkinson’s disease, and informing robotics.

Way mice lick could reveal origins of neurological disorders

Cornell University For the first time, Cornell University researchers have developed a technique for studying the neuroscience of motor control in mice ¬- by focusing on a mouse’s tongue when it licks a water spout. The technique incorporates high-speed cameras and machine learning in a tractable experimental setup that opens the door for revealing mysteries of how the motor cortex works, understanding the neural basis of related disorders like Parkinson’s disease, and informing robots. “We now have an approach in a mouse where we can bring all the tools of modern neuroscience to bear on this really classic problem of motor control,” said senior author Jesse Goldberg, associate professor of neurobiology and behavior.
