Here we combine optogenetics and fMRI to produce a brain-wide 5-HT evoked functional map. We find that DRN photostimulation leads to an increase in the hemodynamic response in the DRN itself, while projection areas predominately exhibit a reduction of cerebral blood volume mirrored by suppression...
Functional connectivity of an engram ensemble with downstream brain areas Brain-wide mapping of the engram of a specific memory confirms that a given memory is not stored in a single brain region but is stored in a chain of engram cell ensembles dispersed in multiple brain regions. This calls ...
Considering the compatibility with deep learning, we map the brain image into a unit rectangle. 如上所述,每个度量由来自两个半球的表面组成。为了使三维成像数据适应二维模型,我们需要将三维皮层网格映射成二维图像。由 FreeSurfer 生成的3D 网格是一个不能直接映射到平面网格的折叠封闭表面。然而,对应于靠近...
If you ever find colors in your map too ambiguous, there are a few things you can do. If you don’t want to change the colormap, you can just drag the datacursor across areas of the surface and this will produce a corresponding datatip on the colormap. In other words, the color o...
2c). When using the adult PTM as anatomical reference for children/adolescents, the locating errors varied as a function of age and were quite considerable (≥ 10 mm) for younger children (aged 6–12 years). These age-related differences in the locating performance showed the highest values ...
The 3D structure of the brain enclosed in the fossil cranium was computationally reconstructed by deforming the average human brain using the deformation function from the average endocast to each fossil endocast (see Methods). The volume of each brain region was also estimated using the ...
The functional anatomy of the social brain remains elusive, however, because social cognition does not simply map onto anatomically defined brain regions. Activity across many cortical regions, including parietal, temporal, prefrontal, and cingulate areas, varies with many social processes, including ...
particularly the brain. Models of different brain areas exist, namely the cortex [25], choroid plexus [26], and thalamus [27]. In the latter model [27], organoids from the thalamus and cortex are fused, mimicking the in vivo interplay between these two brain areas. CNS-based organoids ...
The human extrastriate visual cortex comprises numerous functionally defined areas, which are not identified in the widely used cytoarchitectonical map of
A growing number of studies have used stylized network models of communication to predict brain function from structure. Most have focused on a small set of models applied globally. Here, we compare a large number of models at both global and regional le
