Mitchison's Hypothesis suggests that the human brain's ability to learn and remember is influenced by the structure and function of its neural connections. It proposes that the brain's synaptic connections are not just static but can change dynamically based on experiences, which enhances cognitive flexibility and memory retention. This hypothesis is named after Sir John Mitchison, a British neuroscientist, who emphasized the importance of these adaptable connections in understanding how learning occurs. By focusing on the brain's plasticity, Mitchison's work contributes to the broader field of neuroscience, helping to explain how we acquire and retain knowledge throughout our lives.
