Abstract

The aim of this work was to develop a simple and feasible method of mapping the neural network topology of the mouse brain. Wild-type C57BL/6 J mice (n = 10) aged 8–10 weeks were injected with the cholera toxin subunit B (CTB) tracer in the anterior (NAcCA) and posterior (NAcCP) parts of the nucleus accumbens (NAc) core and in the medial (NAcSM) and lateral (NAcSL) parts of the NAc shell. The labeled neurons were reconstructed using the WholeBrain Calculation Interactive Framework. The NAcCA receives neuronal projections from the olfactory areas (OLF) and isocortex; the thalamus and isocortex project more fibers to the NAcSL, and the hypothalamus send more fiber projections to the NAcSM. Cell resolution can be automatically annotated, analyzed, and visualized using the WholeBrain Calculation Interactive Framework, making large-scale mapping of mouse brains at cellular and subcellular resolutions easier and more accurate.

全脑计算交互框架在全脑神经连接网络映射中的应用

这项工作的目的是开发一种简单可行的绘制小鼠大脑神经网络拓扑的方法。在8–10周龄的野生型C57BL/6 J小鼠（n=10）伏隔核（NAc）核的前部（NAcCA）和后部（NAcCP）以及伏隔核外壳的内侧（NAcSM）和外侧（NAcSL）注射霍乱毒素亚单位B（CTB）示踪剂。使用WholeBrain Calculation Interactive Framework重建标记的神经元。NAcCA接收来自嗅觉区（OLF）和等皮层的神经元投射；丘脑和等角体向NAcSL投射更多的纤维，下丘脑向NAcSM投射更多的光纤。细胞分辨率可以使用WholeBrain Calculation Interactive Framework自动注释、分析和可视化，使以细胞和亚细胞分辨率对小鼠大脑进行大规模映射变得更容易、更准确。

期刊介绍： The Journal of Chemical Neuroanatomy publishes scientific reports relating the functional and biochemical aspects of the nervous system with its microanatomical organization. The scope of the journal concentrates on reports which combine microanatomical, biochemical, pharmacological and behavioural approaches. Papers should offer original data correlating the morphology of the nervous system (the brain and spinal cord in particular) with its biochemistry. The Journal of Chemical Neuroanatomy is particularly interested in publishing important studies performed with up-to-date methodology utilizing sensitive chemical microassays, hybridoma technology, immunocytochemistry, in situ hybridization and receptor radioautography, to name a few examples. The Journal of Chemical Neuroanatomy is the natural vehicle for integrated studies utilizing these approaches. The articles will be selected by the editorial board and invited reviewers on the basis of their excellence and potential contribution to this field of neurosciences. Both in vivo and in vitro integrated studies in chemical neuroanatomy are appropriate subjects of interest to the journal. These studies should relate only to vertebrate species with particular emphasis on the mammalian and primate nervous systems.
