Brainstem: Control Centers of Medulla

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...

Brainstem

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...

Lattice Centering and Coordination Number

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.

Center of Gravity

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...

Center of Gravity

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...

Center of Mass

2.1K
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...

てんかん患者（PWE）は、健常対照群と比較して、息止め課題中に脳幹の活性化が低下していました。この息止め機能的磁気共鳴画像法（fMRI）所見は、てんかんにおける突然死（SUDEP）のリスクのある個人を特定するのに役立つ可能性があります。

科学分野:

  • 神経科学; 呼吸生理学; てんかん研究

背景:

  • てんかん患者（PWE）では、発作周囲性無呼吸が一般的であり、てんかんにおける突然死（SUDEP）に関連している。; PWEにおける無呼吸に対する脳幹呼吸中枢の反応はよく理解されていない。; 息止め（BH）機能的磁気共鳴画像法（fMRI）は、無呼吸中の脳幹機能を調査することができる。

研究 の 目的:

  • 自発的BH課題中のPWEと健常対照群との間の脳幹呼吸中枢活性化の違いを調査する。; BH-fMRIをPWEにおける呼吸制御機能障害を検出するためのバイオマーカーとして評価する。

主な方法:

  • 成人PWEおよび健常対照群は、吸気および呼気BH課題中のfMRIを受けた。; 呼吸数、酸素飽和度、および終末呼気ガスを監視した。; fMRIデータを使用して、脳幹活性化および結合の群レベルおよび個人レベルの分析を実行した。

主要な成果:

  • PWEは、呼気および吸気BHの両方で、対照群と比較して有意に低い群レベルの脳幹活性化を示した。個々の分析では、PWEの35％、特にくさび状核および正中縫線核で脳幹活性化の低下が明らかになった。PWEでは、呼吸およびBHの両方で脳幹-皮質結合の低下が観察された。

結論:

  • PWEのかなりの割合が、脳幹呼吸制御領域における発作間期機能障害を示す。; BH-fMRIは、個人レベルでこれらの異常を検出でき、臨床バイオマーカーとしての可能性を示唆している。; これらの所見を検証し、SUDEPとの関連をさらに調査するには、さらなる研究が必要である。
