Neuropil Variation in the Prefrontal, Motor, and Visual Cortex of Six Felids [0.03%]
六种猫科动物前额皮质，运动皮质和视觉皮质的神经元网络变异分析

Jacob Nelson et al.
Introduction: Felids have evolved a specialized suite of morphological adaptations for obligate carnivory. Although the musculoskeletal anatomy of the Felidae has been studied extensively, the comparative neuroanatomy of ...
The Phylotypic Brain of Vertebrates, from Neural Tube Closure to Brain Diversification [0.03%]
脊椎动物的原型脑，从神经管闭合到大脑多样化
Rodrigo Senovilla-Ganzo,Fernando García-Moreno
Rodrigo Senovilla-Ganzo
Background: The phylotypic or intermediate stages are thought to be the most evolutionary conserved stages throughout embryonic development. The contrast with divergent early and later stages derived from the concept of t...
Organization of Somatosensory Cortex in the South American Rodent Paca (Cuniculus paca) [0.03%]
南美啮齿动物Paca(Cuniculus paca)体感皮层的组织结构

Marco Aurelio M Freire et al.
Introduction: The study of non-laboratory species has been part of a broader effort to establish the basic organization of the mammalian neocortex, as these species may provide unique insights relevant to cortical organiz...
Entopallium Lost GFAP Immunoreactivity during Avian Evolution: Is GFAP a "Condition Sine Qua Non"? [0.03%]
胶质纤维酸性蛋白不是禽类脑皮层发育的必备条件：进化角度的研究
Mihály Kálmán,Olivér M Sebők
Mihály Kálmán
Introduction: The present study demonstrates that in the same brain area the astroglia can express GFAP (the main cytoskeletal protein of astroglia) in some species but not in the others of the same vertebrate class. It c...
Exaptation and Evolutionary Adaptation in Nociceptor Mechanisms Driving Persistent Pain [0.03%]
与持续性疼痛相关的伤害感受机制的征用及进化适应
Edgar T Walters
Edgar T Walters
Background: Several evolutionary explanations have been proposed for why chronic pain is a major clinical problem. One is that some mechanisms important for driving chronic pain, while maladaptive for modern humans, were ...
Convergent Anuran Middle Ear Loss Lacks a Universal, Adaptive Explanation [0.03%]
收敛型蛙类中耳丢失缺失通用的适应性解释
Molly C Womack,Kim L Hoke
Molly C Womack
Introduction: Shared selection pressures often explain convergent trait loss, yet anurans (frogs and toads) have lost their middle ears at least 38 times with no obvious shared selection pressures unifying "earless" taxa....
Hippocampal, Whole Midbrain, Red Nucleus, and Ventral Tegmental Area Volumes Are Increased by Selective Breeding for High Voluntary Wheel-Running Behavior [0.03%]
通过选择性培育提高自愿跑步滚轮活动水平对海马体、全中脑、红核和腹侧被盖区体积的影响
Margaret P Schmill,Zoe Thompson,Daisy Lee et al.
Margaret P Schmill et al.
Uncovering relationships between neuroanatomy, behavior, and evolution are important for understanding the factors that control brain function. Voluntary exercise is one key behavior that both affects, and may be affected by, neuroanatomica...
Sex Differences in the Neural Song Circuit and Its Relationship to Song Acoustic Complexity in House Wrens (Troglodytes aedon) [0.03%]
普通绣眼鸟（Troglodytes aedon）的神经歌曲回路的性别差异及其与歌曲声音复杂度的关系
Cara A Krieg,Juli Wade
Cara A Krieg
The song circuit in passerine birds is an outstanding model system for understanding the relationship between brain morphology and behavior, in part due to varying degrees of sex differences in structure and function across species. House w...

Andrew B Barron
The comparative approach is a powerful way to explore the relationship between brain structure and cognitive function. Thus far, the field has been dominated by the assumption that a bigger brain somehow means better cognition. Correlations...
