This video demonstrates the process of preparing ventral hippocampal and nucleus accumbens tissues from mouse brains for co-culture. Neurons extend projections to form synaptic connections between the ventral hippocampal and nucleus accumbens tissues. This method allows studying neuronal interactions between these two brain regions, offering insights into cognition, behavior, and neurological disorders.

This study describes how to dissect the endolymphatic sac from the inner ear of the mouse at different ages. The result of a similar dissection is shown in an Slc26a4-null mouse model of enlargement of the endolymphatic sac. A transgenic mouse with a fluorescent reporter expressed in the endolymphatic sac is presented as a model to readily visualize the endolymphatic sac, and educational tool.

Ectopic expression is one technique to elucidate the microRNAs role in brain development. However, targeting specific areas using in ovo electroporation is challenging. Here, we show an efficient way to selectively electroporate ventral and dorsal midbrain regions.
FAQs
Its anterior location places it directly adjacent to the posterior surfaces of vertebral bodies and intervertebral discs. This relationship separates the spinal cord or cauda equina from the anterior epidural space and makes the sac an important reference point when assessing how anterior spinal structures relate to neural tissues.
Imaging can show the spatial relationship between the dural sac, vertebral bodies, intervertebral discs, and the anterior epidural space. Recognizing the ventral boundary helps clinicians orient anterior spinal anatomy and evaluate findings relevant to neural structures, particularly when considering disc-related disease or planning treatment near the vertebral canal.
Damage can produce leakage of cerebrospinal fluid from the normally enclosed spinal compartment. Because the injury occurs near the anterior spinal structures, careful recognition is important during diagnosis and treatment. Identifying the possibility of a leak helps clinicians account for dural involvement rather than viewing the finding solely as a problem of the disc or vertebral body.
The sac forms an anatomical boundary between the neural contents and the anterior epidural space. This boundary provides a clinically useful framework for locating structures on spinal imaging and for understanding how procedures near the posterior vertebral bodies or intervertebral discs may relate to the enclosed cerebrospinal fluid and neural tissues.
During decompression planning, clinicians must account for its position next to the posterior vertebral bodies and intervertebral discs. This helps define the relationship between the surgical region and the enclosed neural structures. Careful anatomical planning is particularly important because injury may lead to cerebrospinal fluid leakage and require recognition during treatment.
Its proximity to intervertebral discs makes it a key anatomical consideration in disc surgery. The sac lies between the anterior disc region and the neural contents, so imaging and operative planning must account for this relationship. Awareness of the boundary helps clinicians recognize potential dural involvement if the sac is injured.
Intradural interventions involve the compartment containing the spinal cord, cauda equina, and cerebrospinal fluid, making the dural sac directly relevant to procedural planning. Its ventral position helps clinicians understand the anterior limits of that compartment and anticipate the anatomical relationship between the intervention site and nearby vertebral or disc structures.
