Lesions are?

Explanation:
Lesions are damaged tissue. In neuroscience, a lesion refers to an area of brain tissue that has been harmed by injury or disease, resulting in altered or lost function in that region. It’s about the state of tissue after damage, not the normal tissue itself, nor a process like nerve conduction or the synapses. So a lesion represents brain damage. For context, damage to a specific area can produce deficits tied to that region, such as motor dysfunction from a lesion in the motor cortex.
