LH alpha, also known as lateralization of hemispheric alpha activity, refers to the characteristic brainwave pattern that occurs in the human brain during resting and relaxed states. Alpha waves are a type of electrical activity that can be measured using electroencephalography (EEG), which records the brain's electrical signals.
LH alpha specifically refers to the dominance of alpha waves in the left hemisphere (LH) of the brain. These waves have a frequency range of approximately 8-13 Hertz and are typically associated with a state of wakeful relaxation, reflecting a reduced level of mental activity.
The lateralization of alpha activity refers to the fact that alpha waves are not uniformly distributed across both brain hemispheres. Research suggests that the LH alpha activity is an indicator of increased right-hemisphere involvement and inhibition of the left hemisphere, indicating a state of relaxed alertness or focused attention.
The LH alpha pattern is often observed in tasks that involve introspection, creativity, and non-linear thinking. Moreover, it has been associated with enhanced performance in certain cognitive functions, such as visual and spatial processing, emotional expression, and artistic ability.
Overall, LH alpha represents a specific brainwave pattern that reveals the predominance of alpha waves in the left hemisphere during states of relaxed mental activity. Its presence may indicate increased involvement of the right hemisphere and may be linked to specific cognitive functions and mental states.
