Source: Lauer, S. M., et al. Visualization of Cortical Modules in Flattened Mammalian Cortices. J. Vis. Exp. (2018) This video demonstrates a method to visualize the cortical modules in flattened brain sections using histochemical staining. Pre-fixed sections are treated with a straining reagent that highlights active neural clusters, forming dark, high-contrast regions. After mounting and dehydration, cortical modules appear under a bright-field microscope as dark, patchy patterns.

Generation of Spontaneous and On-Demand Ictal Events in Mouse Brain Cortical Slices

2025
This video demonstrates the induction of ictal events in coronal cortical slices from a transgenic mouse expressing light-activated cation channels in cortical excitatory pyramidal neurons. The slice is placed in a recording chamber, and a recording electrode is inserted into the superficial cortical layer. Upon perfusion with a seizure-inducing drug that blocks potassium channels, the neurons become hyperexcitable and generate spontaneous ictal events. To generate on-demand ictal events, a...

A simple and reliable method on isolation and culture of neural stem cells from discarded human fetal cortical tissue is described. Cultures derived from known human neurological disorders can be used for characterization of pathological cellular and molecular processes, as well as provide a platform to assess pharmacological efficacy.
FAQs
Cortical layers organize neural activity into interconnected regions that receive, integrate, and transmit information. This layered arrangement allows signals to move through coordinated circuits rather than remaining within isolated groups of cells. Examining how activity is distributed across layers can therefore help researchers relate cortical organization to sensory processing, voluntary movement, learning, and higher cognition.
Neurons and glial cells contribute to cortical function through coordinated activity. Neurons communicate using electrical signals and synaptic interactions, while the tissue’s broader cellular organization supports the operation of interconnected cortical circuits. Studying both cell types is important because cortical behavior emerges from interactions among neural cells, not from neuronal signaling considered in isolation.
Electrical signals allow cortical neurons to transmit information, while synaptic communication enables signals to influence other cells within interconnected circuits. Together, these processes support the reception, integration, and transmission of information across cortical tissue. Investigating them helps explain how coordinated neural activity contributes to perception, memory, learning, movement, and other higher-level functions.
Researchers examine the relationship between cortical layers, interconnected neural circuits, and the functions associated with the cerebrum. Comparing tissue organization with patterns of information processing can provide insight into perception, memory, voluntary movement, learning, and higher cognition. This approach also supports investigation of how altered cortical structure or activity may relate to neurological disorders.
Experimental models and tissue analyses are central approaches for investigating cortical brain tissue. They allow researchers to examine its cellular organization, layered structure, neural circuits, and patterns of communication. Depending on the research question, these approaches can be used to study normal cortical function as well as development, injury, disease mechanisms, and possible restoration of cortical function.
Cortical tissue analysis is useful when researchers need to investigate how organization and cellular activity relate to brain function or dysfunction. It can support studies of neural circuits, brain development, perception, memory, injury, and neurological disorders. The resulting observations help connect tissue-level features with broader questions about cortical processing and impaired function.
Research on cortical brain tissue can reveal how changes in neural circuits, cellular organization, or communication relate to disease mechanisms. Experimental models and tissue analyses provide ways to examine these changes in the context of neurological disorders and injury. Such work may also inform strategies aimed at understanding or restoring impaired cortical function.
Cortical models can help researchers investigate how neural circuits and layered tissue organization relate to development and later function. Tissue analyses can also be applied to injury, allowing scientists to examine altered cortical features and their possible effects on information processing. These studies connect developmental and injury-related changes with broader questions of cortical recovery and function.
