Gamma notes

Gamma brainwave notes from a blog. I'm mostly posting 'succinct summary' stuff here aside from later experiments so for more detail I'll give links.

Paraphrased; condensed

Gamma -- determined by the amount of synchronous gamma firing -- has been positively associated with children's language development, cognitive skills, behavior and impulse control, and found to be lower in children whose parents had history of language impairment. Previous research in adults & animals says Gamma heightens during the processing of linguistic information, during the formation of ideas and memories and during other abilities. It fires between 2 regions of the brain during associative learning, when a new concept is linked to one already known.

Low gamma coherence within different hemispheres is associated with ADD and learning disabilities. Children with non-verbal learning disabilities had less connectivity in the right hemisphere. Too much Gamma is associated with ADHD, positive associations in Schizophrenia (i.e. hallucinations) and epilepsy, and Alzheimer’s disease, and negative symptoms of Schizophrenia (i.e. blunt or flat affects).

Gamma training in children 6-16 with non-verbal learning disabilities had positive effects, enhancing various non-verbal cognitive abilities such as processing speed, freedom from distractibility, arithmetic and coding. (2x weekly, 35 minute BWE sessions, alternating between excitatory [14 Hz to 40 Hz ramp-up] and inhibitory [40 Hz to 14 Hz ramp-down].
