<p>Mu rhythm&nbsp; is a monomorphic “wicket rhythm” and is often a tick faster than the individual’s alpha peak frequency (i.e. if one’s alpha peak is at 10Hz, they would present mu at 11+ hz typically). Mu always presents in C3 and C4, over the sensory motor cortex, when the mirror neurons are not engaged. Mu is an indication of frontal lobe disengagement.</p><p>As a baby, mirror neurons enable us to mimic our parents, and “motherese” (a parent’s repeating the “goo -goo” and “gaa-gaa” of babies) enables us to learn speech sounds. We learn all these things by mimicking. Burgoon (1985): 60% of human communication is non-verbal and mu is a sign that non-verbal communication is not being seen or perceived by the brain.</p><p>Mimicking and mirroring speech is controlled by the brain’s frontal central loop and central-temporal loop (The temporals allow for the perceptual comprehension of the mimicry). The right-hand side of the sensory motor strip of the brain (C4) is responsible for mimicking impressions and the emotional tone of speech, as well as integrate empathy, and emotion. Mirror neurons on the left (C3) lay down language. Oxytoxin is for social bonding and oxytocin attenuates mu.&nbsp; Oxytocin is a hormone produced in the hypothalamus and released by the pituitary, which plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth.&nbsp; When we are creating oxytocin, we cannot create mu.&nbsp;</p><p>If you suspect mu and you ask your patient to wiggle their fingers, the presence of mu will disappear.&nbsp; It is noteworthy that Mu is present in 70% of the autistic population, whereas only 15% of the fully normal population has mu and 50% of the ADHD population have it, as well as 50% of Affective Disorders.</p><p style="text-align: center;"><img src="@@PLUGINFILE@@/rhythm-eeg.png" alt="Mu Rhythm in Raw EEG" width="788" height="1105" class="img-responsive atto_image_button_middle"><br></p><p style="text-align: center;">Figure : Mu Rhythm in Raw EEG<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/qeeg-mu-rhythm.png" alt="qEEG of Mu Rhythm" width="663" height="553" class="img-responsive atto_image_button_middle"><br></p><p style="text-align: center;">Figure : qEEG of Mu Rhythm<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/raw-qeeg-harmonic.png" alt="Raw qEEG representation of mu (red box) and harmonic of mu (green box)" width="571" height="661" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : Raw qEEG representation of mu (red box) and harmonic of mu (green box)<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/z-scores-mu.png" alt="Mu in 17 year old girl, Z-Scores" width="715" height="650" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : Mu in 17 year old girl, Z-Scores<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><br></p>
