網頁2012年5月16日 · This determines the effect of genotype and host species on the brain-body volume relationship as ANCOVA does for linear regression [Warton et al., 2006]. We used an independent-samples Kruskal-Wallis test to compare body length, brain volume, body volume and relative brain volume between genotypes. 網頁2010年2月24日 · In this functional magnetic resonance imaging study we tested whether the predictability of stimuli affects responses in primary visual cortex (V1). The results of this study indicate that visual stimuli evoke smaller responses in V1 when their onset or motion direction can be predicted from the dynamics of surrounding illusory motion. We conclude … clive bowen jug網頁2 天前 · A key function of the mammalian neocortex is to process sensory data in the context of current and past stimuli. Primary sensory cortices, such as V1, respond weakly to stimuli that typical in their context but strongly to novel stimuli, an effect known as "deviance detection".

網頁2015年5月15日 · We conclude that it is possible to study separate functional connections from visual to motor cortices using paired-TMS with an ISI in the range 18-40 ms. The connections are inhibitory at rest and possibly mediated by inhibitory interneurones in the motor cortex. The effect with an ISI of 40 ms reverses into facilitation during a … 網頁雅思听力场景词汇国家，城市名称，地名，专有机构名称，专有名词： UK= the United Kingdom 英国 Scotland 苏格兰 Ireland 爱尔兰 Wales 威尔士 Australia 澳大利亚 Queensland 昆士兰 Sydney 悉尼 New Zealand 新…
