A Comparative Study on Land Use/Land Cover Change and Topographic Gradient Effect between Mountains and Flatlands of Southwest China

Land, 2023
Topography plays an important role in restricting the formation of and change in land use/land cover (LULC) patterns. To compare the LULC change and topographic gradient effects between mountains and flatlands, the geo-informatic atlas, terrain position ...

Vegetation differentiation characteristics and control mechanisms in the Altay region based on topographic gradients

Ecological Indicators
Among numerous vegetation studies, there are few studies on the elevation gradient distribution control mechanism and horizontal law of small-scale vegetation. In the same climate zone, topography is one of the most important factors affecting vegetation

Abnormal cortical topographic patterns associated with auditory verbal hallucination in first-episode schizophrenia [PDF]

Translational Psychiatry
Convergent phenomenological and neuroimaging evidence support that the dysregulated segregation and integration between brain networks have been implicated in the neural mechanism of auditory verbal hallucination (AVH) in schizophrenia. Nevertheless, the

Topographic gradients of intrinsic dynamics across neocortex [PDF]

eLife, 2020
The intrinsic dynamics of neuronal populations are shaped by both microscale attributes and macroscale connectome architecture. Here we comprehensively characterize the rich temporal patterns of neural activity throughout the human brain.

Vagus Topographic Map: Wandering through a gRAdient [PDF]

Developmental Cell, 2020
Topographic map development requires precise coordination between navigating axons and their targets in a dynamic environment. In this issue of Developmental Cell, Isabella et al. describe a mechanism in which a changing gradient of the morphogen retinoic acid regulates the expression of guidance factors to shape topographic axon targeting.
