Isolation of Microglia from the Cortex of an Adult Mouse Brain

2025
The video demonstrates a technique for isolating microglia from the cortex of an adult mouse brain. First, the cortex undergoes segmentation and homogenization to remove neurons and other glial cells, preserving microglia. Following that, the cell suspension is exposed to anti-myelin magnetic microbeads and a magnetic field, effectively separating microglia and myeloid cells from myelin debris and cells containing myelin.

Recording of Local Field Potential in Mouse Hippocampal-Entorhinal Cortex Slices
0 Views •
2025
The video demonstrates a procedure to record the local field potential (LFP) in mouse hippocampal-entorhinal cortex slices. Electrical stimulation is provided at the CA3 stratum radiatum of the hippocampus, which causes changes in the postsynaptic potential at the CA1 stratum pyramidale. The combined change in the membrane potential of CA1 neurons, termed the local field potential, is recorded.
FAQs
Layered organization means that cortical circuits can be examined according to both depth and area rather than as a uniform sheet. Distinct layers and regions contain interconnected circuits whose coordinated activity supports perception, movement, learning, and higher-order processing. This organization gives researchers a framework for asking where particular functions arise and how activity is integrated across the cortex.
Different cell populations contribute complementary roles to cortical circuit activity. Excitatory and inhibitory neurons provide interacting sources of activity, while glial cells are also part of the cellular environment in which those circuits operate. Studying them together helps researchers interpret circuit behavior as a coordinated network rather than attributing a function to one cell type in isolation.
Anatomical tracing examines how cortical cells and regions are interconnected, providing structural information about circuit organization. Unlike approaches focused primarily on activity, tracing emphasizes relationships among circuit elements. In mouse cortex studies, this information can be paired with electrophysiology, calcium imaging, or optogenetics to relate connectivity to circuit function and behavior.
These methods provide complementary ways to investigate cortical circuits and connect cellular activity with behavior. Electrophysiology, calcium imaging, and optogenetics can be selected according to the activity or circuit question being examined, while anatomical tracing adds information about connectivity. Using multiple approaches helps researchers relate observations across cellular, circuit, and behavioral levels.
A study can begin by selecting a cortical layer, area, or cell population, then examining its activity or connectivity with one or more established methods. Researchers can next relate those measurements or manipulations to behavior. This workflow supports analysis at multiple levels, from cells and circuits to observable functions, while preserving the cortex’s anatomical organization.
Mouse cortex research is especially useful for studying neural development, sensory processing, plasticity, and disease mechanisms. It also provides experimental frameworks for testing theories of brain function. The value lies in connecting organized cortical circuits with cellular activity and behavior, allowing researchers to investigate both normal processing and changes associated with disease.
