概括
左前带带皮层 (ACC) 的下转化与一生中患重度抑郁症 (MDD) 的风险更高有关. 这种大脑结构的变化可能表明MDD个体的早期发病和更高的神经病变.
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:
- 重度抑郁症 (MDD) 是一种普遍存在的全球精神疾病.
- 皮层转化正在成为潜在的抑郁症早期风险标志物.
- 前带带皮层 (ACC) 参与情绪调节和抑郁.
研究的目的:
- 为了研究左ACC化作为MDD的潜在生物标志物.
- 探索ACC旋转模式与MDD特征之间的关联.
- 检查ACC化和个性特征之间的关系.
主要方法:
- 对皮层表面重建的中间视图进行分析,以测量旋转.
- 基于专家评价者对左ACC旋转模式的评估.
- 在MDD和没有MDD的个体之间比较变异变异.
- 与疾病发病年龄和人格分数 (神经主义,外向) 的相关性分析.
主要成果:
- 特定的左侧ACC旋转模式 (较少的前后旋转) 在有MDD病史的人群中更为常见 (p = .048).
- 这种较少gyri变异的个体经历了较早发病的MDD (d = -0.30).
- 左侧ACC中较少的纵向旋转与较高的神经病症得分相关 (η2= .02).
- 自动回旋和表面积测量通常支持专家的发现.
结论:
- 左ACC转化可能作为MDD的早期表型标志物,可能反映早期发育因素.
- 这一发现需要在高风险人群中以及使用先进的神经成像技术进行进一步的研究.

G-protein Coupled Receptors
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.
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 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,...
Depressive Disorders: MDD and Dysthymia
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
Depressive Disorders: Etiology
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
