Neural oscillation
Neural Oscillation
Neural oscillation (pronunciation: /ˈnʊərəl ˌɒsɪˈleɪʃən/), also known as brainwave activity, refers to the rhythmic or repetitive neural activity in the Central nervous system.
Etymology
The term "neural oscillation" is derived from the Latin neuralis meaning "of the nerves" and the Latin oscillatio meaning "a swinging".
Definition
Neural oscillation is a fundamental mechanism that the brain uses to organize the flow of neural information. It is characterized by the rhythmic or repetitive electrical activity generated by neurons or neural networks in the brain.
Types of Neural Oscillation
There are several types of neural oscillations, categorized by their frequency:
- Delta waves (0.5–4 Hz)
- Theta waves (4–8 Hz)
- Alpha waves (8–12 Hz)
- Beta waves (12–30 Hz)
- Gamma waves (30–100 Hz)
Function
Neural oscillations are critical for various brain functions, including sensory processing, motor control, and cognitive functions such as attention, memory, and intelligence.
