Sensory Substitution: The process through which information from one sensory modality is presented to another sensory modality, allowing individuals with a lost sense to perceive stimuli through a different intact sense.
Cross-modal Plasticity: The ability of the brain to reorganize and adapt by reallocating functions from the lost sensory area to other remaining areas in response to sensory deprivation or loss.
Synesthesia:A neurological condition where stimulation of one sensory or cognitive pathway leads to automatic and involuntary experiences in another pathway. It is not directly related to compensating for a lost sense, but it demonstrates the brain's ability to create unique connections between different senses.
