Rewire

Rewire is a verb with several related meanings. In its most literal sense, to rewire is to replace, modify, or reconfigure electrical wiring within a building or device. Rewiring can address safety hazards, upgrade capacity, or change circuit layouts. Because electrical systems pose risk of fire or electric shock, rewiring is generally performed by licensed electricians and must comply with applicable codes and standards, such as national or local electrical code requirements.

In neuroscience and psychology, rewire is used metaphorically to describe the brain's capacity to alter its neural connections in response to experience, learning, or injury. Neuroplasticity underpins neural rewiring, enabling recovery after brain damage, adaptation to new skills, or shifts in behavior. Therapies, rehabilitation programs, and consistent practice can contribute to lasting changes in synaptic networks.

In everyday language, individuals may speak of rewire one's habits or mindset, signaling deliberate alteration of routines, beliefs, or cognitive patterns. In organizational or technical contexts, rewire can refer to reconfiguring systems, networks, or workflows to improve efficiency or resilience.
