The idea that when one sense is lost, the remaining senses may become more acute is a common belief, and there is some evidence to support this notion. This phenomenon is often referred to as "sensory compensation."
When a person loses a sense, such as sight or hearing, their brain may adapt to the change by enhancing the sensitivity or acuity of the remaining senses. For example, studies have shown that individuals who are blind may develop heightened touch and hearing capabilities. This adaptation can occur due to neural plasticity, where the brain reorganizes itself in response to changes in sensory input.
However, the extent of sensory compensation can vary from person to person, and not everyone experiences a significant enhancement of their other senses after losing one. Factors such as the person's age, the duration of the sensory loss, and their individual experiences and training can all play a role in how the remaining senses are affected.
In summary, while there is some evidence that losing one sense can lead to strengthened abilities in others, the experience is highly individual and can vary widely.
