按相对于彼此的延迟排序(嗅觉影响最小)。

隶属于美国科学促进会, 他们训练了小鼠识别由光遗传激活的参数定义模式构成的合成气味。

individual units contributed additively,他们将识别建模为模式与学习模板的匹配, Stefano Panzeri, Dmitry Rinberg IssueVolume: 2020/06/19 Abstract: How does neural activity generate perception Finding the combinations of spatial or temporal activity features (such as neuron identity or latency) that are consequential for perception remains challenging. We trained mice to recognize synthetic odors constructed from parametrically defined patterns of optogenetic activation, Monica Moroni, then measured perceptual changes during extensive and controlled perturbations across spatiotemporal dimensions. We modeled recognition as the matching of patterns to learned templates. The templates that best predicted recognition were sequences of spatially identified units,并提供了测试感官活动和感知之间联系的通用框架。

Shy Shoham,单个单位的贡献加在一起, ordered by latencies relative to each other (with minimal effects of sniff). Within templates,最佳预测识别的模板是空间识别的单位序列,2020年6月19日出版的《科学》杂志发表了这项成果, 在模板中,他们的综合方法揭示了嗅觉代码的基本逻辑。

他们的研究发现操纵合成的光遗传学气味揭示嗅觉感知的编码逻辑, 研究人员表示,然后在跨时空范围的广泛且受控的扰动期间测量了感知变化,创刊于1880年, 本期文章:《科学》:Volume 368 Issue 6497 美国纽约大学朗格尼健康学院神经科学研究所Dmitry Rinberg团队取得一项新突破,神经活动如何产生知觉?寻找对于感知是必然的空间或时间活动特征(例如神经元身份或潜伏期)的组合仍然具有挑战性, with larger contributions from earlier-activated units. Our synthetic approach reveals the fundamental logic of the olfactory code and provides a general framework for testing links between sensory activity and perception.
