Status of Noninvasive Brain Stimulation in the Therapy of Alzheimer's Disease
Wherever you write a keyword like "Brain wave stimulation improves..." you will find thousands of articles on researches, findings. Last but not least, researchers proposed the existence of numerous EEG phenotypes. EEG phenotypes were derived through Johnston, Gunkelman, & Lunt's (2005) extensive clinical experience.
Ben-Gurion University of the Negev (BGU) researchers have discovered a promising biomarker for predicting and potentially preventing epileptic seizures in patients with brain injuries using EEG (electroencephalographic) recordings of theta brain waves.
International MRI meta-analysis creates first global map of bipolar disorder.
A new landmark study—which is the largest meta-analysis of MRI brain imaging to date—has identified specific brain abnormalities in gray matter volumes of people with bipolar disorder (BD) and created the first “roadmap” of key brain regions underlying the neurobiology of BD. These findings were published May 2 online ahead of print in the journal Molecular Psychiatry.
Bipolar brain imaging shows how the bipolar brain is different.
The picture below shows a significant reduction in grey matter volume.
It comes from a study of patients with bipolar disorder.
It shows grey matter shrinking prefrontal and temporal regions of the brain.

Tolman proposed that complex animal behavior is mediated by the cognitive map, an integrative learning system that allows animals to reconfigure previous experience in order to compute predictions about the future.
The frequency of human brain waves has a range of 0.5 – 70 Hz with various amplitudes and symmetry. Equilibrium between the waves in right and left brain (inter-hemispherical symmetry) is also an important factor. Natural brain frequencies are designated as alpha: 8-12 Hz; beta, 12-30; theta: 4.0-8.0 Hz; delta: 0.5-4.0 Hz, and gamma: 30 Hz and above.
Normal frequencies of the human brain associated states are shown below. These frequencies can be picked up by an EEG (Electroencephalogram) from the surface of the brain, after their amplification, as they are in the range of micro-volts. A mixture of these frequencies is present at any given time. Quantitative Electroencephalography (QEEG) is an extension of the analysis of the visual EEG interpretation which may assist and even augment our understanding of the EEG and brain function. QEEG is a procedure that processes the recorded EEG activity from a multi-electrode recording using a computer and converts it into a brain map showing different brain waves.
Bellabee now connects to a BrainMaster Atlantis or Echo using an adapter from 3.5 mm to 2.5 mm jacks.
