北京大学心理与认知科学学院纳家 勇治 灵长类 下颞叶 位置信息 双编码特征
2020/8/20
沿视觉腹侧通路至海马的感知信息处理通常被认为伴随视网膜空间到关系空间的转换，后者表征视觉元素间相互关系而丢失了各自源自视网膜的位置信息。然而，我们的视觉感知多有类似视网膜映射的第一视角体验。纳家组发现，恒河猴下颞叶的神经元既可以表征基于关系空间的、支持物体再认的物体客体信息，也可以表征基于视网膜空间、支持物体定位的物体位置信息，两者共同成为实现第一视角体验的重要神经基质。这项研究于2020年7月8...
Earliest look at newborns' visual cortex shows that babies are hard-wired to see faces and places（图）
Earliest newborns visual cortex shows babies hard-wired faces and places
2020/3/13
Within hours of birth, a baby's gaze is drawn to faces. Now, brain scans of newborns reveal the neurobiology underlying this behavior; in babies as young as 6 days, brains appear to be hardwired for t...

Complex cognitive functions, such as learning and memory, arise from the interaction of multiple brain regions that comprise functional circuits and different components of these circuits make unique ...
Bose-Einstein condensation of tunnelling photons in the brain cortex as a mechanism of conscious action
Quantum brain dynamics (QBD) consciousness

A salient feature of prefrontal cortex organization is the vast diversity of cell types that support the temporal integration of events required for sculpting future responses. A major obstacle in und...
The Effects of Cimetidine and Ranitidine on Kidney Cortex of Mus musculus albinus
Cimetidine ranitidine kidney mouse
2010/3/30
In this study, 4.3 µg/g cimetidine and 17 µg/g ranitidine were orally given to mice for two months. The effects of cimetidine and ranitidine on kidney cortical tissue were examined at ligh...
