Dorsal Forebrain Dissection

Dorsal forebrain dissection is a biological technique used to isolate the dorsal portion of the developing forebrain for structural, cellular, and molecular analysis. The procedure relies on identifying anatomical landmarks and carefully removing surrounding tissue while preserving the target region, allowing researchers to examine its organization and development under controlled conditions. Dissected tissue can support histological analysis, gene-expression studies, cell culture, and investigations of neural differentiation. By separating the dorsal forebrain from adjacent brain regions, this method helps clarify region-specific developmental mechanisms and provides experimental material for studying nervous-system formation and neurological disease.

2007

This video demonstrates the protocol for isolating and culturing explants of the mouse forebrain from embyonic day 12 mice. Procedures for removal of the uterus, embryos from uterus, and dissection of embryos are given. In addition the methodology for transferring these explants onto specialized membranes on which they are cultured is demonstrated. The development of the forebrain can be studied in vitro using this preparations as well as changes in gene expression.

This video demonstrates two methods for preparing and placing beads, which have been coated with growth factor, on explants of the developing cerebral cortex. These beads can be used to induce spatially restricted gene expression on developing neural tissue such as forebrain explants. Methods are given for using both Affi-Gel beads and heparin acryllic beads.

The abdominal dorsal vessel of the honey bee and other insects serves as the functional equivalent of the mammalian heart and plays an important role in nutrient transport, waste removal, immune function, and more. Here we describe a protocol for the visualization and pharmacological manipulation of bee heart rate.

Dissection and Isolation of Mouse Dorsal Root Ganglia

2026

Dorsal root ganglia (DRG) contain primary sensory neuron cell bodies and relay peripheral sensory signals to the spinal cord. This protocol describes a method for mouse DRG dissection that supports standardized isolation of structurally intact ganglia, anatomical segmental identification, intuitive guidance for novice users, and reduced procedural tissue injury.
