Abstract

Advances in brain imaging have led to a paradigm shift in neuroscience research, moving from focusing on individual brain structures to investigating neural networks and connections. However, neuroanatomy education still tends to concentrate on discrete brain regions. Two separate experiments in undergraduate neuroscience courses investigated whether incorporating neural connectivity into neuroanatomy education would enhance learning. Students in each experiment learned to identify brain structures through computer-based training sessions that provided text-based narrative feedback about neural connections, followed by final memory tests after a 1-month delay. The first experiment included 30 students and demonstrated a long-term memory benefit associated with described neural connections, showing a medium effect size (p = 0.01, d = 0.54) comparable to the established retrieval practice effect for enhancing long-term memory (p = 0.03, d = 0.47). The second experiment replicated the benefits of described neural connections with a small effect size (p = 0.005, d = 0.28) in a larger sample of 122 students across classrooms at two universities. Furthermore, students remembered the functional outcomes of neural connections from training (p < 0.001, d = 0.46), and this generalized to clinical applications (p = 0.009, d = 0.27). In contrast, categorizing brain areas without describing neural connections (as is commonly done in introductory neuroscience textbook chapters) did not benefit either memory or generalization. Findings demonstrate that leveraging the connectivity paradigm shift in neuroscience research can enhance neuroanatomy education. Emphasizing neural connections and their functional outcomes helps simplify neuroanatomy and improve understanding and retention.

摘要

脑成像技术的进步已导致神经科学研究的范式转变,从专注于单个脑结构转向研究神经网络和连接。然而,神经解剖学教育仍倾向于集中在离散的脑区。本科神经科学课程中的两项独立实验研究了将神经连接纳入神经解剖学教育是否会提高学习效果。每个实验中的学生通过基于计算机的培训课程学习识别脑结构,这些课程提供有关神经连接的基于文本的叙述性反馈,然后在延迟1个月后进行最终记忆测试。第一个实验包括30名学生,证明了与所描述的神经连接相关的长期记忆益处,显示出中等效应量(p = 0.01,d = 0.54),与已确立的用于增强长期记忆的检索练习效应相当(p = 0.03,d = 0.47)。第二个实验在两所大学的122名学生的更大样本中重复了所描述的神经连接的益处,效应量较小(p = 0.005,d = 0.28)。此外,学生记住了训练中神经连接的功能结果(p < 0.001,d = 0.46),并且这推广到了临床应用(p = 0.009,d = 0.27)。相比之下,对脑区进行分类而不描述神经连接(如神经科学入门教科书章节中通常所做的那样)对记忆或推广均无益处。研究结果表明,利用神经科学研究中的连接范式转变可以增强神经解剖学教育。强调神经连接及其功能结果有助于简化神经解剖学并提高理解和记忆。
