The part of the brain in people born blind that usually handles visual information in sighted people develops a unique connectivity pattern. This pattern in the primary visual cortex is said to be unique to each individual, much like a fingerprint

A Brain Fingerprint: Study Uncovers Unique Brain Plasticity in People Born Blind - Georgetown University Medical Center
A study led by Georgetown University neuroscientists reveals that the part of the brain that receives and processes visual information in sighted people develops a unique connectivity pattern in people born blind.
People with aphantasia still activate their visual cortex when trying to conjure an image in their mind’s eye, but the images produced are too weak or distorted to become conscious to the individual

Mind blindness decoded: people who can’t see with their ‘mind’s eye’ still activate their visual cortex, study finds
People with aphantasia still have a blueprint for mental imagery, even if they can’t consciously ‘see’ it.

Scientists find abnormally slow neural dynamics in visual cortex of depressed individuals
New brain imaging reveals unusual slowness in the visual cortex of individuals experiencing major depression. This altered activity, linked to symptom severity, highlights a connection between visual processing and the broader depressive state.
Using awake fMRI, researchers found that 2 month old infants already have structured visual categories in ventrotemporal cortex, resembling adult patterns. This shows the brain organizes complex visual information far earlier than previously believed.

Infants have rich visual categories in ventrotemporal cortex at 2 months of age
Nature Neuroscience - Using infant fMRI, the authors show that, by 2 months of age, representations in high-level visual cortex encode visual categories that align with deep neural networks,...
