background beta waves Explanation: "de fondo" in this context is more related to background and when it says "ritmo" it could also refer to "onda" or wave, as i am proposing. hope this helps Example sentence(s):

beta background Explanation: Beta background Beta background rhythm Beta background activity Background beta activity Ver, por ejemplo, In stage N3, background beta activity is largely replaced by delta waves. https://books.google.es/books?id=1XwCww-EgggC&pg=PA47&lpg=PA... higher background beta activity with mid-range peaks at 23-24, 28, and wide distribution at 37-39Hz range. https://www.google.com/url?sa=t&source=web&rct=j&url=http://... The females in this sample had significantly more background beta activity than the males https://www.google.com/url?sa=t&source=web&rct=j&url=https:/... identifying elements within the beta background https://books.google.es/books?id=eGICOzEkQ9QC&pg=PA163&lpg=P... The EEG revealed a predominant beta background rhythm, upon which was thrust generalised repetitive spike and polyspike waves followed by slow wave discharges https://www.google.com/url?sa=t&source=web&rct=j&url=https:/... more theta and some beta background activity https://www.sciencedirect.com/science/article/pii/S007961230... |

Reference: Ritmo beta Reference information: From a downloaded document: Ritmo beta El ritmo beta es definido en base a su frecuencia: > 13 Hz, en general, 18-25 Hz. La actividad > 30 Hz tiene escasa amplitud y no suele ser registrada con técnicas convencionales. La amplitud es usualmente baja (5-10 μV); excepcionalmente supera los 30 μV, voltaje que es considerado anormal por muchos autores. De manera característica es simétrico en regiones homólogas de los dos hemisferios. La asimetría significativa (> 35%) o persistente suele deberse a factores extracerebrales (defecto óseo, alteraciones del cuero cabelludo, etc.) o es patológica. Un defecto óseo disminuye la resistencia al paso de la corriente eléctrica, originando un incremento de la actividad beta cerca o a distancia del mismo (ritmo de brecha). -------------------------------------------------- Note added at 2 hrs (2020-01-31 22:11:31 GMT) -------------------------------------------------- I was going to suggest an answer but then had second thoughts! I think the key words are beta, activity and background. Beta Activity Beta activity is defined as a frequency of 13–30 Hz and is present in the background of most subjects. If completely absent it may represent an abnormality depending on other features of the EEG. Maximal beta amplitude is usually in the frontocentral regions, but it may be widespread. It does not respond to eye opening, as does the PDR. During drowsiness, beta may seem to increase in amplitude. This appears to be a function of amplitude diminution of other background frequencies and thus is more apparent than real. https://www.sciencedirect.com/topics/nursing-and-health-prof... Topics to be covered include the normal waking background rhythm (alpha rhythm); beta activity; mu, theta, and lambda waves; activation effects on the EEG; and features of normal sleep. 5. BETA ACTIVITY Beta activity (>13 Hz) is defined by three relatively distinct frequency bands: 18 to 25 Hz activity, which is the most frequently encountered; 14 to 17 Hz activity, which is less common; and the still rarer, greater than 25 Hz activity. The first two frequencies are seen commonly over the frontal regions and become more prominent as the subject gets drowsy. These two beta rhythms are usually of low voltage ( |
