概括
患有早期精神病的个体在海马体中表现出前部CA1和牙状环体积减少. 这些发现表明,早期的海马体子场变化可能有助于精神病的机制.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 神经解剖学是一个神经解剖学.
背景情况:
- 海马体积减少是精神分裂症的一个已知的特征.
- 早期精神病的确切时间和特定的子领域参与仍然不清楚.
研究的目的:
- 为了研究早期精神病中的海马子子子场体积差异.
- 为了测试早期精神病前部CA1体积减少的假设.
主要方法:
- 利用高分辨率T2加权的MRI成像海马子场.
- 在不同地区测量了特定子领域 (CA1,CA2/3,dentate gyrus, subiculum) 的体积.
- 将90名患有早期非情感性精神病障碍的人与70名健康对照人进行比较.

Role of Hippocampus in Memory
252
The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
648
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
