Cerebellar culmen-substantia nigra tract assisted rehabilitation post stroke: a case report

An 88-year-old right-handed man was admitted to our hospital for cognitive impairment and right-sided paralysis. His head non-contrast computed tomography (CT) showed large low-density areas (LDA) and fibrous structures in the left occipital and temporal lobe regions. Despite the fact that it had been more than 10 years since his stroke, rehabilitation was effective. This is a rare case in which cerebellar culmen -substantia nigra tract assisted rehabilitation after stroke.

Assessment of Differential Forest Growth Following Disturbance in Minnesota, USA

We used LiDAR metrics and satellite imagery to examine regeneration on forested sites disturbed via harvest or natural means over a 44-year period. We tested the effectiveness of older low-density LiDAR elevation data in producing information related to existing levels of above ground biomass (AGB). To accomplish this, we paired the elevation data with a time series of wetness and greenness indices derived from Landsat satellite imagery to model changes in AGB for sites experiencing different agents of change. Current AGB was determined from high-density LiDAR acquired in northern Minnesota, USA. We then compared high-density LiDAR-based AGB and estimates modeled using Landsat and low-density LiDAR indices for 10,068 sites. Clear differences were found in standing AGB and accumulation rates between sites disturbed by different agents of change. Biomass accumulation following disturbance appears to decrease rapidly following an initial spike as stands 1asZX respond to newly opened growing space. Harvested sites experienced a roughly six-fold increase in the rate of biomass accumulation compared to sites subjected to stand replacing fire or insect and disease, and a 20% increase in productivity when compared to sites subjected to wind mediated canopy loss. Over time, this resulted in clear differences in standing AGB.
