Summary: Neurons found to be abnormal in psychosis play an important role in our ability to distinguish between what is real and what is perceived, researchers say.

New Western University research shows that neurons in the part of the brain found to be abnormal in psychosis are also important in helping people distinguish between reality and imagination.
The researchers, Dr. Julio Martinez-Trujillo, principal investigator and professor at Western University’s Schulich School of Medicine & Dentistry and Dr. Diego Mendoza-Halliday, postdoctoral researcher at M.I.T., investigated how the brain codes visual information in reality versus abstract information in our working memory and how those differences are distributed across neurons in the lateral prefrontal cortex region of the brain. The results were published today in Nature Communications.
“You can look at my shirt, and then if I move out of your vision, even with your eyes open you can still see the colour of my shirt in your mind,” explained Martinez-Trujillo, based at the Brain and Mind Institute and Robarts Research Institute at Western University. “That is what we call working memory representations or short-term memory representations – they are abstract, they are imaginary and they don’t exist in reality, but in our minds. Real objects in our visual field, we call perceptual representations. We are trying to determine whether there are neurons in the brain that can signal to a person whether a representation is real or imaginary.”

(Reuters) -Leon Russell, who emerged in the 1970s as one of rock ‘n’ roll’s most dynamic performers and songwriters after playing anonymously on dozens of pop hits as a much-in-demand studio pianist in the 1960s, died on Sunday at age 74.
Russell, who was inducted into the Rock and Roll Hall of Fame in 2011, died in his sleep in Nashville, Tennessee, his wife said in a statement on his website.
Russell suffered health problems in his later years, having surgery to stop leaking brain fluid in 2010 and suffering a heart attack in July 2016.
“He was recovering from heart surgery in July and looked forward to getting back on the road in January,” said his wife, Jan Bridges.
Russell’s period of stardom as a performer was relatively brief, but Elton John, who had once been Russell’s opening act, engineered a comeback for him in 2010 when they collaborated on an album titled “The Union.”
“He was my biggest influence as a piano player, a singer and a songwriter,” John told ABC News.
Russell recorded more than 35 albums and also excelled as a songwriter for other performers. His “A Song for You” was recorded by Joe Cocker, the Carpenters, the Temptations, Neil Diamond, Lou Rawls, Dusty Springfield, Ray Charles, Aretha Franklin and good friend Willie Nelson. The Carpenters, Helen Reddy, Shirley Bassey, Robert Goulet and George Benson all covered Russell’s “This Masquerade,” with Benson’s version winning the 1976 Grammy as record of the year.
Russell was known as “the master of space and time” in his 1970s heyday. He wore a cocked top hat, and with salt-and-pepper hair past his shoulders and a beard that reached his chest, created an inscrutable image that was equal parts shaman, tent revival preacher and cosmic ringmaster.
He ruled the stage with piano-banging abandon and, backed by a multi-piece band and a backup chorus, put on a show that was a roiling stew of rock, soul, gospel and country.
Russell’s last performance was July 10 in Nashville
