Deans' stroke musings: Nuts and Brain Health: Nuts Increase EEG Power Spectral Density (μV&[sup2]) for Delta Frequency (1–3Hz) and Gamma Frequency (31–40 Hz) Associated with Deep Meditation, Empathy, Healing, as well as Neural Synchronization, Enhanced Cognitive Processing, Recall, and Memory All Beneficial For Brain Health

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Nuts and Brain Health: Nuts Increase EEG Power Spectral Density (μV&[sup2]) for Delta Frequency (1–3Hz) and Gamma Frequency (31–40 Hz) Associated with Deep Meditation, Empathy, Healing, as well as Neural Synchronization, Enhanced Cognitive Processing, Recall, and Memory All Beneficial For Brain Health

I'm sure your stroke hospitals don't have enough brains to figure this out and create a protocol for a daily serving of nuts. But you knew that already, on your own once again.

Abstract

Nuts are a major source of flavonoids. They are potent antioxidants with known mechanisms that provide cardioprotective, anticarcinogenic, and anti-inflammatory properties. Studies have shown that absorbed flavonoids penetrate and accumulate in brain hippocampal regions involved in learning and memory. Neurobiological correlates of flavonoids cascade an expression of neuroprotective and neuromodulatory proteins that promote neurogenesis, blood-flow improvement, and angiogenesis supporting brain wellness. However, the correlates of neuroelectric activities that are associated with nut flavonoid effects on neurocognition, neuronal synchronization, memory, recall, mood and behavior are not well known.

Purpose

Provide evidence of a relationship between antioxidant concentration in nuts and electroencephalography (EEG) brain state frequency modulation, specifically gamma wave band frequency 31–40 Hz (γBA).

Methods

A study was conducted using walnuts, pecans, pistachios, peanuts, cashews and almonds. EEG Power Spectral Density μV² (PSD) was acquired during a sequence of enhancing sensory awareness tasks ranging from cognition of past experience, visualization, olfaction, taste, and finally consumption of nuts. EEG wave band activity was recorded from 9 cerebral cortical scalp regions F3, Fz, F4, C3, Cz, C4, P3, Pz and P4 using the FDA approved EEG B-Alert 10X System^™, Carlsbad, CA. Second by second 9 bandwidths (BW) were recorded through the study. The PSD BW data were referenced to eyes closed baseline task, and then Z-scored.

Results

Z-scores were graphed and analyzed for each task along with BW across 0–40 Hz. The overall respective BW were collapsed across all 9 EEG channels. With descriptive analysis, the most profound observation was Gamma and Delta wave band frequencies showed the highest PSD response during the TASK of placement of the nuts in mouth (p<0.01). The lowest PSD response for all nuts studied was alpha slow frequency. It was observed that both δBA and γBA were highest for pecans with an antioxidant concentration of 1743 μmoles; followed by walnuts, with an antioxidant concentration of 2772 μmoles; and for cashews, with an antioxidant concentration 48 μmoles.

Conclusion

This study provides objective evidence that PSD for different brain EEG wave bands are modulated differentially by different types of nuts. We propose this protocol as an assessment tool to determine the efficacy of various types of nuts effecting modulation of EEG frequency bands 0–40 Hz & subsequent neurochemical modulation. However, the primary purpose of this study was to focus specifically on δBA 1–3 Hz and γBA 31–40 Hz so as to determine if the suggested benefits of nuts are associated with significant increases in these specific frequencies. These data appear to support an association of nuts’ health benefits with an increase in δBA and γBA. Further research needs to be done to elaborate and understand the significance of these unique frequency patterns and ratios relative to nut consumption and brain health.
