Brain & Nicotine
Brain imaging studies suggest people who smoke regularly from a young age tend to reduce activity in the prefrontal cortex of the brain. They perform less on tasks, also memory and attention are affected compared to people who don't smoke.
Doctor Sergio Jaramillo, Neurologist at Baptist Health Neuroscience Center agrees and adds that the prefrontal cortex is a part of the brain that gives people their personalities, helps them make decisions and inhibits certain behaviors. “It's a kind of filter of the brain. The nicotine can affect this part of the brain," he affirms.
