概括

大型抑郁症 (MDD) 涉及到变化的条纹区. 这项研究发现,膜和尾膜的矩阵和体体积发生了变化,与MDD的严重程度和症状相关.

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.
神经成像是一种神经成像.

背景情况:

状体对奖励和动机至关重要,具有明显的矩阵和状体部分,涉及神经精神疾病.
大型抑郁症 (MDD) 的功能网络异常选择性地与体相互作用,表明MDD的隔间不平衡.
之前评估MDD的条纹区分的方法仅限于死后组织分析.

研究的目的:

在重大抑郁症 (MDD) 中调查状矩阵和状体区功能中的潜在不平衡.
开发和应用新的体内方法来评估MDD的状区特异性变化.

主要方法:

在266名受试者 (MDD患者和健康对照) 的队列中使用了概率扩散通道图 (基于连接的分片).
识别了呈现矩阵状和状体状连接模式的条状,与已知的解剖特征进行验证.
量化了门和尾状核内的特定区块体积变化.

主要成果:

在MDD患者中证实了胺体积的减少,从矩阵样比例明显转变为状体样比例.
在MDD患者中观察到尾状核的相反转移,从类似于体的到类似于矩阵的体积.
发现尾状体积变化与MDD症状的严重程度相关.

结论:

MDD与变化的条形状体体积有关,特别是向形状体主导的转变.
门中的这些隔间特定的体积变化可能代表MDD临床特征的神经解剖相关性.
这些发现凸显了体内神经成像在重大抑郁症中揭示条状区功能障碍的潜力.

Long-term Depression

Long-term Depression

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

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
