Resumen
Las personas con epilepsia (PWE) muestran una activación reducida del tronco cerebral durante las tareas de contención de la respiración en comparación con los controles. Este hallazgo de la resonancia magnética funcional (fMRI) de retención de la respiración puede ayudar a identificar a las personas en riesgo de muerte súbita e inesperada en epilepsia (SUDEP).
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Fisiología de las vías respiratorias.
- Investigación de la epilepsia en la investigación de la epilepsia.
Sus antecedentes:
- La apnea periictal es común en personas con epilepsia (PWE) y está relacionada con la muerte súbita inesperada en epilepsia (SUDEP).
- La respuesta del centro respiratorio del tronco encefálico a la apnea en PWE no se comprende bien.
- La resonancia magnética funcional (fMRI) con retención de la respiración (BH) puede investigar la función del tronco cerebral durante la apnea.
Objetivo del estudio:
- Para investigar las diferencias en la activación del centro respiratorio del tronco cerebral entre PWE y controles sanos durante las tareas voluntarias de BH.
- Para explorar el potencial de BH-fMRI como un biomarcador para la detección de la disfunción del control respiratorio en PWE.
Principales métodos:
- Adultos PWE y controles sanos se sometieron a fMRI durante las tareas inspiratorias y expiratorias BH.
- Se monitorearon la frecuencia respiratoria, la saturación de oxígeno y los gases de las mareas finales.
- Se realizaron análisis a nivel de grupo e individual de la activación del tronco cerebral y la conectividad utilizando datos de IRMf.
Principales resultados:
- El PWE exhibió una activación del tronco cerebral a nivel de grupo significativamente más baja durante el BH tanto expiratorio como inspiratorio en comparación con los controles.
- Los análisis individuales revelaron una activación reducida del tronco cerebral en el 35% de las PWE, particularmente en los núcleos de rafe cuneiformes y medianos.
- Se observó una reducción de la conectividad tronco encefálico-cortical en PWE durante la respiración y BH.
Conclusiones:
- Una proporción significativa de PWE muestra disfunción interictal en las regiones de control respiratorio del tronco cerebral.
- BH-fMRI puede detectar estas anomalías a nivel individual, lo que sugiere un potencial como biomarcador clínico.
- Se necesita más investigación para validar estos hallazgos y explorar su vínculo con SUDEP.

4.4K
The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...

The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

12.2K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

6.8K
The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

2.2K
The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

The center of mass is the point at which the total mass of an object can be said to be concentrated. It is a fundamental principle in mechanics and physics that applies to all objects regardless of their shape or size. The center of gravity is the point at which an object’s weight appears to be concentrated and can be used to balance the object perfectly.
The knowledge of the center of mass can also help us to describe and predict the motion of objects. For example, when a ball is thrown...
