Lots of Neurofeedback specialist wants to complicate, trying to put Bellabee in the same gasket as they are thought from NFB protocols, trying to place Bellabee all over the head like electrodes.
Bellabee sends signals through the whole lobe, not just to the one part of the brain. Our brains do not have Faraday cages around parts of them, to be able targeting only one area. It is not logical, isn't it?
OK, I wanted to show you this, how inducing 40Hz therapy helping with Alzheimer's and why.
As you know, in Bellabee Health app you already can find pre-set ALZ-ME therapy with 40 Hz.
An important set of studies demonstrating the link between gamma activity and AD was published by Iaccarino et al. using primarily the 5XFAD mouse model of AD . An important cell type of interest in the study was that of interneurons, that diverse collection of neural cells that vary in morphology, connectivity, and physiology . The results of  demonstrated reduced levels of the power of gamma activity in the hippocampus of the 5XFAD mice relative to the wild type. Further, this reduction in gamma activity was observed before the accumulation of amyloid plaque or evidence of cognitive impairment. It was further shown that increasing gamma activity in the CA1 region of the hippocampus, by stimulation of optogenetically modified interneurons using blue light at 40 Hz, reduced Aβ levels by approximately 50% and was mediated by both neural and microglia mechanisms. The neural response was evidenced by reduced AβPP degradation as well as modifications to endosomal activity. Microglia activity was increased with both genetic evidence of upregulation in the microglia of genes related to phagocytosis, and histological evidence of microglia adopting phagocytotic morphology, increasing in numbers in the area under study and an increase in the number of microglia with internalized Aβ. These effects were also observed in the visual cortex, with 40 Hz white light stimulus supplied as an externally flickering source observed visually by the mice. Importantly, the external supply of the stimulus, delivered via the retina, optic nerve and subsequent pathways was translated as an increase in gamma activity in the visual cortex.
Gamma electrical activity is associated with cognitive and other related activities with a disturbance in normal patterns of activity seen in patients of AD [18, 36, 107]. The 40 Hz frequency value seems of particular neurological importance and as such represents a natural target value [19, 43, 47, 48, 50, 56]. Stimulatory sources acting in this band, and resultant ERPs and SSRs do indeed show promise for clinical application to AD with studies reporting efficacy in both mouse models of the disease  and cognitive end points when applied to humans .
