概括
脊髓损伤 (SCI) 改变了口味,增加了肥胖风险. 垂直袖子胃切除术 (VSG) 有效地降低了SCI老鼠的糖分摄入量,可能比非SCI肥胖症更能恢复味觉敏感度.
科学领域:
- 神经科学是一个神经科学.
- 代谢手术 代谢手术
- 肥胖问题研究研究
背景情况:
- 脊髓损伤 (SCI) 经常导致大约三分之二的受影响个体超重和肥胖.
- 减肥手术,如垂直袖子胃切除术 (VSG),是对肥胖和2型糖尿病的高效长期治疗方法.
研究的目的:
- 为了研究饮食诱导的肥胖和SCI的老鼠对垂直袖子胃切除术 (VSG) 的反应.
- 为了比较VSG对SCI和没有SCI的老鼠口味反应和食物偏好的影响.
主要方法:
- 雄性Wistar大鼠接受了T3伤脊髓损伤 (SCI) 或假手术.
- 在康复后,大鼠在接受VSG之前,被养高能量,高脂肪饮食 (HFD) 六周.
- 评估了口味反应和偏好,以及通过cFos免疫组织化学在背部阴道综合体中的神经元激活.
主要成果:
- 在HFD暴露之前,SCI大鼠对糖和的味道反应发生了变化.

Spinal Cord
2.0K
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

The Spinal Cord
31.9K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Spinal Cord: Information Processing
3.6K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Spinal Cord: Gross Anatomy
5.9K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

Spinal Cord: Cross-sectional Anatomy
5.0K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

The Physiology of Taste
7.9K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...
