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...
Complimentary Roles of the Hippocampus and Retrosplenial Cortex in Behavioral Context Discrimination

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

Fetal alcohol spectrum disorders (FASD) is the leading neurodevelopment deficit in children born to women who drink alcohol during pregnancy. The hippocampus and cortex are among brain regions vulnera...
针对发光二极管（LED）分选设备对光电参数测量系统的需求，研制了一种基于Cortex-M3（以下简称M3）的快速LED光电参数（包括光参数和电参数两部分）测量系统。该系统分为光参数检测模块（自制光谱仪）、电参数测量模块及显示模块等3部分。光参数检测模块采用M3作为主处理器，对测量获得的光谱数据进行计算，进而得出实测的LED光参数，并将光参数传递给同样以M3为主处理器的电参数测量模块。利用该系统架构...

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...
Measurement of Distribution of Blood-flow Change in Exposed Cortex by Laser Speckle Flowgraphy
Laser Speckle Blood flow Imaging
2009/6/2
The change in the cortical blood flow of guinea pigs during auditory stimulation is measured by laser speckle flowgraphy (LSFG). Accuracy of LSFG depends on the number of the frames for the blood flow...
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...
