                                            Create a realistic portrait of Stephen Kuffler, a middle-aged man with a gentle expression, sitting in a library or study surrounded by books and papers, wearing a suit and tie, with a subtle background that hints at his connection to neurobiology, such as a diagram of a neuron or a simple illustration of the human brain; the style should be formal and academic, reflecting his profession as a neuroscientist and professor.
