Cortical regions in our brain have a hard time processing sensory information. This is because each region focuses on specific types of senses, like vision or hearing. Here are some challenges they face:

1. Sensory Modularity: Different parts of the brain, like the occipital lobe for seeing and the temporal lobe for hearing, sometimes have trouble working together. This makes it harder to put together all the information we receive.

2. Plasticity Limits: Our brains can change a bit to recover from injuries, but sometimes damage is too severe. These permanent issues can make it tough for people to heal and get better.

3. Complex Pathways: Sensory information travels through many steps in the brain, using connections called synapses. This can lead to slowdowns or delays when processing what we see and hear.

To help with these challenges, there are special therapies. These include exercises to retrain our senses and tools that can help us adapt. Together, these approaches can improve recovery and help different senses work better together.
