RESUMEN

Introducción:

El registro con microelectrodos en la estimulación cerebral profunda (ECP) ha demostrado una gran utilidad. Es posible mejorar su eficiencia caracterizando las propiedades de los potenciales de acción extracelulares (PAE). Pacientes y

métodos:

Hemos analizado registros de nueve pacientes operados por epilepsia o agresividad bajo anestesia general. Se han determinado las propiedades de los PAE de los núcleos talámicos centromediano, ventral intermedio, ventrocaudal e hipotalámico posteromedial.

Resultados:

Hemos analizado 706 células talámicas y 142 hipotalámicas. La proporción de tipos celulares resultó específica de cada núcleo celular. El tipo celular más frecuente fue P1P2N1 (59,5%), seguido por N1P1N2 (23,1%). La primera fase del PAE es altamente variable. Las propiedades de las fases del PAE de la misma morfología difieren altamente entre núcleos.

Conclusiones:

Hemos demostrado que diversos núcleos cerebrales profundos tienen propiedades específicas de la morfología de los PAE. Esto permitirá una mejora en la localización de estos núcleos durante la ECP.(AU)
ABSTRACT

Introduction:

Using microelectrodes for recording purposes in deep brain stimulation (DBS) has proven to be very useful. Their efficiency can be improved by characterising the properties of extracellular action potentials (EAPs). Patients and

methods:

We analysed the records of nine patients who underwent surgery for epilepsy or aggressiveness under general anaesthesia. The properties of the EAPs of the centromedian, ventral intermediate, ventrocaudal and posteromedial hypothalamic nuclei of the thalamus have been determined.

Results:

We have analysed 706 thalamic and 142 hypothalamic cells. The proportion of cell types was found to be specific to each cell nucleus. The most frequent cell type was P1P2N1 (59.5%), followed by N1P1N2 (23.1%). The first phase of the EAP is highly variable. The properties of the EAP phases of the same morphology differ greatly from one nucleus to another.

Conclusions:

We have shown that several deep brain nuclei have properties that are specific to the morphology of the EAPs. This will allow for improved localisation of these nuclei during DBS.(AU)
