OK I know brain waves are cyclic but do they use the same electrons throughout or do they switch between electrons?

000guy said:Also are all neurotic electrons constantly connected by electromagnetic fields?
samsracecar said:To answer your first question, thoughts are carried through different paths throughout neurons.

mishrashubham said:This would help us give a useful reply, since "neurotic electrons" doesn't make sense, and I googled that term just to be sure, but found nothing.
000guy said:OK another question, if information (like memory) is stored in neurons is the same neuron used for recalling that memory?
ALso are the same neurons used for identical thoughts, experiences, etc.?
If you read the wiki article you linked to on EEG's you'll see that it asserts that what an EEG picks up is not "electrochemical action potentials traveling down neurons in a neural network" but a phenomenon called "volume conduction":ryan_m_b said:Brain waves* are the result of electrochemical http://en.wikipedia.org/wiki/Action_potential" .
*the electrical activity read by electroencephalography.
Neurons are electrically charged (or "polarized") by membrane transport proteins that pump ions across their membranes. Neurons are constantly exchanging ions with the extracellular milieu, for example to maintain resting potential and to propagate action potentials. Ions of like charge repel each other, and when many ions are pushed out of many neurons at the same time, they can push their neighbours, who push their neighbours, and so on, in a wave. This process is known as volume conduction. When the wave of ions reaches the electrodes on the scalp, they can push or pull electrons on the metal on the electrodes. Since metal conducts the push and pull of electrons easily, the difference in push or voltage between any two electrodes can be measured by a voltmeter. Recording these voltages over time gives us the EEG.[4]
The electric potentials generated by single neurons are far too small to be picked by EEG or MEG.[5] EEG activity therefore always reflects the summation of the synchronous activity of thousands or millions of neurons that have similar spatial orientation. If the cells do not have similar spatial orientation, their ions do not line up and create waves to be detected. Pyramidal neurons of the cortex are thought to produce most EEG signal because they are well-aligned and fire together. Because voltage fields fall off with the square of the distance, activity from deep sources is more difficult to detect than currents near the skull.[6]
brain wave

A rhythmic fluctuation of electric potential between parts of the brain, as seen on an electroencephalogram.

The only "travel" involved, if you want to speak of travel here, is the travel of positive ions from outside the cell to the inside, and visa versa. The EEG is not picking up the travel of signals from, for example, thalamus to cortex.
Brain waves are patterns of electrical activity produced by the brain. They are measured using an electroencephalogram (EEG) and are categorized into different types based on their frequency and amplitude.
Brain waves can indicate the level of activity and alertness in the brain. They can also provide insight into certain mental states, such as relaxation, concentration, or sleep.
Brain waves play a crucial role in our daily lives as they help regulate our thoughts, emotions, and behaviors. They also influence our sleep patterns, memory, and overall brain function.
While brain waves are not fully under our conscious control, certain techniques such as meditation and biofeedback can help individuals learn to regulate their brain waves and achieve specific mental states.
Some common brain disorders related to brain waves include epilepsy, sleep disorders, and attention deficit hyperactivity disorder (ADHD). Abnormal brain waves can also be a symptom of other neurological conditions, such as Alzheimer's disease and Parkinson's disease.
