NFBs

NFBs is an acronym that can refer to multiple concepts across different domains. The intended meaning is usually clear from context.

In psychology and neuroscience, neurofeedback (often abbreviated NFB) is a form of biofeedback that provides real-time information about brain activity, typically via EEG, to help individuals regulate neural activity. It has been explored for a range of conditions, including ADHD, anxiety, and sleep disorders, and is sometimes pursued as a non-pharmacological treatment option. The evidence for efficacy varies by condition and protocol, and practices differ among clinics and researchers.

In film and media governance, NFB commonly denotes national film boards, most prominently the National Film Board of Canada. Several countries maintain national film bodies with similar roles, including producing and distributing documentary and artistic films, promoting national cinema, and supporting media arts. The names and structures of these organizations vary by country, but they share a mandate to support cultural audiovisual production.

In systems theory and engineering, negative feedback loops (NFBs) are regulatory mechanisms that counteract deviations from a set point, contributing to stability in mechanical, electronic, biological, and ecological systems. They are fundamental in controlling processes such as temperature regulation, enzyme activity, and population dynamics, helping systems maintain homeostasis against disturbances.

In policy analysis, non-financial benefits (NFBs) refer to advantages not expressed in monetary terms, such as improvements in health, environmental quality, or social equity. While often more difficult to quantify than financial gains, non-financial benefits are increasingly considered in decision-making and impact assessments to capture broader societal value.
