Brain Imaging01:14

Brain Imaging

651
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

657
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

755
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

科学领域:

  • 神经科学是一个神经科学.
  • 认知科学 认知科学

背景情况:

  • 大麻的大量使用与认知缺陷有关.
  • 大麻会影响内分泌大麻素受体,影响神经网络,对马波段反应至关重要.
  • 以前的研究集中在高阶处理上,忽视了基本的马电路完整性.

研究的目的:

  • 调查大麻大量使用对基本玛电路完整性和功能连接性的影响.
  • 检查常规大麻使用者和非使用者的视觉诱导任务期间视觉皮层中的马波段反应.

主要方法:

  • 高密度磁脑电图 (MEG) 用于84名常规大麻使用者和90名人口统计学上匹配的非使用者.
  • 参与者接受了用马波段闪频率 (32 40 和 48 Hz) 的视觉诱导任务.
  • 时间频率分析和动态功能连接计算以评估神经活动和网络相互作用.

主要成果:

  • 在双边初级视觉皮层 (V1) 中观察到强烈的马引入,32 Hz 响应是最强的.
  • 右V1活动在不同群体和频率中比左V1活动强.
  • 与对照组相比,大麻组在V1和更高阶视觉区域之间显示了32Hz的功能连接性.

结论:

  • 在大量使用大麻的人群中,基本的马电路似乎完好无损.
  • 强度大麻使用优先影响玛功能连接,特别是在初级和高级视觉区域之间.
  • 改变的玛功能连接性可能是与大麻使用相关的观察到的高阶认知缺陷的基础.
