Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The study of how damage to the brain affects cognitive functioning has historically been one of the most important tools for cognitive neuroscience. While the brain is one of the most well protected parts of the body, there are many events that can affect the functioning of the brain. Vascular issues, tumors, degenerative diseases, infections, blunt force traumas, and neurosurgery are just some of the...

A Technique for Harvesting and Dissociating Dorsal Root Ganglia for Neuronal Cultures
0 Views •
2025
This video demonstrates a method for harvesting neurons from the dorsal root ganglia (DRG). DRG from a rat's spinal column is isolated, treated with enzymes, and then mechanically dissociated to obtain a single-cell suspension. The neurons are separated from glial cells using density gradient centrifugation and cultured in a growth medium.

Stock Split

2025
A stock split is a corporate action aimed at increasing the number of a company's shares by dividing its existing shares into multiple new ones. This adjustment reduces the per-share price without altering the company's overall market capitalization, thereby making shares more affordable to investors and enhancing trading flexibility. Stock splits are often employed by companies whose stock prices have risen significantly, making their shares less accessible to retail investors. Lowering the...

This video demonstrates how to maintain the growth of human embryonic stem cells (hESCs) in feeder cell-free conditions and how to continuously passage hESCs in feeder cell-free conditions. Confirmation of hESC pluripotency grown in feeder cell-free conditions by immunofluorescence microscopy is also demonstrated. Part 2 of 3.
FAQs
The method compares root portions exposed to different conditions while they remain part of the same plant. A response limited to one compartment suggests local root adjustment, whereas changes in shoots or in the untreated root portion indicate systemic signaling or resource redistribution. This distinction helps researchers connect environmental heterogeneity with coordinated plant behavior.
These processes provide possible routes for information and resources to move between differently treated root sections and the rest of the plant. Chemical signals can communicate local stress, while water transport and nutrient allocation can alter growth beyond the exposed compartment. Measuring these linked responses helps reveal how roots and shoots coordinate environmental adjustment.
Uneven treatment recreates situations in which a plant encounters contrasting soil conditions rather than one uniform environment. Separate compartments can represent differences in nutrient supply, drought, salinity, contaminants, or microbial interactions. Comparing the resulting local and systemic responses shows whether the plant adjusts selectively, reallocates resources, or responds throughout its connected root and shoot system.
Researchers divide a plant’s root system between separate soil compartments, establish a distinct environmental condition in each compartment, and then compare responses among the exposed root portions and the rest of the plant. The design can include contrasting nutrient, water, salinity, contaminant, or microbial conditions. Measurements are interpreted by separating local effects from systemic effects.
The approach is useful when the research question concerns spatial variation in soil conditions. Instead of applying one treatment uniformly, investigators can examine how a plant responds when only part of its root system encounters drought, salinity, uneven nutrients, contaminants, or differing microbial interactions. This makes the technique relevant to heterogeneous soils, plant adaptation, and ecosystem studies.
Results can clarify root-to-shoot communication, resource-allocation strategies, and the relationship between local soil conditions and whole-plant performance. Studies may use these outcomes to examine adaptation to environmental stress, beneficial or harmful microbial interactions, and ecosystem function. The findings also support research aimed at sustainable crop management under variable nutrient or water conditions.
