Using high-resolution diffusion magnetic resonance imaging (dMRI) and a suite of old and new staining techniques, the beginnings of a multi-scale connectome map of the squid brain is erected. The first of its kind for a cephalopod, this includes the confirmation of 281 known connections with the addition of 145 previously undescribed pathways. These and other features suggest a suite of functional attributes, including (1) retinotopic organization through the optic lobes and into other brain areas well beyond that previously recognized, (2) a level of complexity and sub-division in the basal lobe supporting ideas of convergence with the vertebrate basal ganglia, and (3) differential lobe-dependent growth rates that mirror complexity and transitions in ontogeny.

使用高分辨率扩散磁共振成像（dMRI）和一套新旧染色技术，建立了鱿鱼大脑的多尺度连接组图。这在头足类动物中尚属首次，其中包括确认 281 个已知连接，并添加了 145 个先前未描述的路径。这些和其他特征表明了一系列功能属性，包括（1）通过视叶进入其他大脑区域的视网膜专题组织远远超出了之前认识的范围，（2）基底叶的复杂性和细分水平支持以下想法：与脊椎动物基底神经节的融合，以及（3）反映个体发育复杂性和转变的差异性脑叶依赖性生长速率。
