"He was an extraordinary man – a colorful bird against the background of academic gray. A scholar and erudite, he was witty, malicious, surprising, uncompromising and courageous. His knowledge and talent for lecturing made him a valued popularizer of neuroscience. He could simplify even very complex phenomena, showing their essence and meaning. Non-standard interpretations of the reality that he presented at the lectures were witty, but also deep and attracted fascinated youth. He loved Krakow – he knew everything about it and was a great guide. There is grief and anger in us that he was driven over at the pedestrian crossing by a delivery van."

“He is an outstanding pharmacologist and at the same time a man who is obsessed with popularizing – in the best sense of the word. He does it great, gathering thousands of listeners on various occasions.”

“A truly Renaissance personality. Absolutely undisputed authority, world-renowned scholar, a real neuroenthusiast who can also spray such a cascade of wit and humor that all anecdotes should hide!”

“Empathy and aggression – although seemingly very distant from each other – have a largely similar neurobiological background and are often intertwined. Besides, our entire legal system is based on the fact that excessive empathy activates centers of aggression.”

“As I walk through my beloved Krakowski Park and pass by a group of young people from which I can smell beer, I give them a wide berth. But when I feel the weed, I go boldly through their group and sometimes chat. Yes, the abuse of marijuana causes trouble with memory, concentration, but it is a short-lived condition. I'm not talking about extreme cases, but there are few of them. Less than after alcohol. Oneself should sometimes detach from reality to deal with it somehow.”

“I met Jurek many years ago when he was only little older than his beloved grandson now. And he was just as nice and at the same time extremely handsome!”

“With all due respect for the title of professor. Vetulani, however, is a unique moron.”
