                                            Generate a realistic image of a British physiologist and chemist in a formal setting, possibly in a laboratory or with a backdrop of a prestigious institution, reflecting his contributions to neuroscience and biophysics. The subject, a middle-aged to elderly man with a dignified appearance, should be dressed in formal attire, potentially including glasses and holding a subtle prop related to his work, such as a neuron model or an electrode. Incorporate elements that signify his achievements, such as a Nobel Prize medal or a Royal Society logo, subtly into the scene or his attire. The style should be photorealistic, capturing the essence of a notable figure in the history of science.
