Spanish term or phrase: Re: eyes and EOG (medical)
See two extracts below containing the difficult term in CAPITALS

“Un movimiento ocular se define como la aparición en el EOG de un grupo de ondas de gran amplitud y baja frecuencia sobre la actividad de fondo de las señales, DE MODO SÍNCRONO EN AMBOS OJOS Y DE SENTIDO OPUESTO. Los movimientos oculares rápidos (REM) se presentan en forma de picos de pendiente marcada y corta duración, mientras que los movimientos oculares lentos (NREM), son de pendiente más suave y de mayor duración”

“El proceso de detección de movimientos oculares se realiza en dos pasos: primero, se localizan los tramos de señal que alcanzan amplitudes elevadas y, segundo, se compara la actividad ocular de ambos ojos, con el fin de comprobar que en esos tramos se cumplen las condiciones de SINCRONISMO BINOCULAR Y SENTIDO OPUESTO”.

It’s not clear to me if the ‘sentido opuesto’ refers to the signal or in fact the eyes. I suspect the former. Would there be a central line, with ‘waves’ depicted on each side of it?

Also, if the contributor happens to know whether NREM and not SEM (for slow) is the term used for 'slow' i.e. 'non-rapid' eye movements.
(I found no refs in web for SEM, but yes for NREM, yet SEM was used in the original academic paper))

Explanation:
The words you request are translated as "binocular synchrony and opposite direction"

The [opposite direction] refers to both the waves in the EOG and the actual eye movement; it can be seen by any observer when someone else looks to the side without moving the head: the right eye moves outside (to the right), and the left eye moves inside (to the right, too), synchronically (or vice versa). To achieve synchronicity in eye movement, different eye muscles are involved for each eye.

Thanks Elena; I was hoping that a doctor or medical expert would confirm, as I needed to be sure that a direct translation would be appropriate. Thanks to angolano too, but it was an explanation I was after more than anything

PS Elena: I'm an MD ('an' because any sound that when spoken produces a vocalised effect (an 'em-dee')is preceded by 'an'.

I will translate the entire sentence to show context:


Explanation:
An ocular movement is defined as the appearance on the Electro-oculogram (EOG) of a group of large amplitude low frequency waves, over the background activity signals, synchronized between both eyes but in the opposite direction. The rapid eye movements (REM) are represented as peaks of big amplitude and short duration, whereas the slow eye movements (NREM) have a shorter amplitude and longer duration.

The process of detection of eye movements is accomplished in two steps: first locate the wave signals reaching high amplitudes and secondly compare the eye activity of both eyes to prove that these waves fit the conditions of binocular synchronism and opposite direction.”

I guess that the acronym “REM” is widely known, so it’s probably best to use “Non-REM” (NREM) for slow movements instead of “SEM”

Cumplimentos. Atentamente,
