概括

患有互联网游戏障碍 (IGD) 的个体表现出大脑网络动态的改变,在被剥夺了游戏时,在基底和边缘网络中增加了招募和整合. 这与娱乐游戏玩家形成鲜明对比,突出了成的神经差异.

科学领域:

神经科学是一个神经科学.
精神病学是一个精神病学.
计算神经科学是一种神经科学.

背景情况:

互联网游戏障碍 (IGD) 越来越令人担忧,但其在实际游戏中的神经支仍然不清楚.
以前的研究经常使用间接的实验任务,限制了对现实游戏场景的洞察力.

研究的目的:

在真实游戏环境中调查IGD患者的动态大脑网络重新配置.
应用人 - 情感 - 认知 - 执行 (I-PACE) 模型的交互来理解IGD的神经机制.

主要方法:

功能磁共振成像 (fMRI) 用于扫描30名IGD游戏玩家和37名娱乐游戏用户 (RGU).
在网上游戏和即时游戏剥夺期间记录了大脑活动.
社区结构分析计算了招聘和整合系数,以评估大脑网络的动态.

主要成果:

在IGD组中,基底状腺网络 (BGN) 和边缘网络 (LN) 在剥夺后的招募增加.
在IGD群体中,在剥夺期间,在前额-双肩网络 (FPN) 和BGN/LN之间观察到更大的整合.
RGU集团保持了稳定的网络招聘和整合,在剥夺期间,BGN招聘率较低.

结论:

患有IGD的游戏玩家表现出更强烈的渴望和情绪反应,在游戏中断时对这些冲动的控制受损.
网络动态中的这些神经差异有助于解释IGD患者游戏的持续成性质.
这些发现为互联网游戏障碍背后的机制提供了直接的神经证据.

Long-term Potentiation

Long-term Potentiation

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Disorders of the Nervous Tissue

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Traumatic Brain Injury l: Introduction

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
