Preparation of Parasagittal Slices for the Investigation of Dorsal-ventral Organization of the Rodent Medial Entorhinal Cortex

We describe procedures for preparation and electrophysiological recording from brain slices that maintain the dorsal-ventral axis of the medial entorhinal cortex (MEC). Because neural encoding of location follows a dorsal-ventral organization within the MEC, these procedures facilitate investigation of cellular mechanisms important for navigation and memory.

2018
Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.

Generation of Medial Thalamus-Anterior Cingulate Cortex Slices from Mouse Brains

2025
The video demonstrates the preparation of medial thalamus-anterior cingulate cortex (MT-ACC) slices from mouse brains. A mouse's brain is dissected, cuts are made to expose the MT-ACC pathway, and slices are generated using a vibratome. The MT-ACC slices are then maintained in oxygenated artificial cerebrospinal fluid.

The present work provides a comprehensive set of guidelines for manually tracing the medial temporal lobe (MTL) structures. This protocol can be applied to research involving structural and/or combined structural-functional magnetic resonance imaging (MRI) investigations of the MTL, in both healthy and clinical groups.

Dorsal Root Ganglia Neurons and Differentiated Adipose-derived Stem Cells: An In Vitro Co-culture Model to Study Peripheral Nerve Regeneration

Dorsal root ganglia (DRG) are structures containing the sensory neurons of the peripheral nervous system. When dissociated, they can be co-cultured with SC-like adipose-derived stem cells (ASC), providing a valuable model to study in vitro nerve regeneration and myelination, mimicking the in vivo environment at the injury site.
FAQs
The nerve's branching pattern shapes the sensory map clinicians interpret. After its usual origin from the superficial fibular nerve, it courses toward the medial foot and divides into digital branches. Those branches may overlap through communications with the saphenous and deep fibular nerves, so a sensory deficit may be incomplete rather than confined to one sharply bordered patch.
Communications with the saphenous and deep fibular nerves can create overlapping sensory territories. Consequently, preserved sensation does not necessarily exclude involvement of the dorsal medial nerve, and an abnormal area may extend beyond the territory expected from a single branch. Recognizing this overlap improves anatomical interpretation during examination and reduces overconfidence in sharply defined sensory boundaries.
Localization depends on matching the sensory change with the medial dorsum of the foot and forefoot, then considering the nerve's course and digital divisions. Clinicians can also account for possible communications with the saphenous and deep fibular nerves. This distribution-based reasoning helps distinguish a localized peripheral sensory problem from a broader or differently positioned deficit.
Clinical assessment compares cutaneous sensation across the medial dorsum of the foot and forefoot, then relates any abnormality to the expected course and terminal branches. This process helps localize a possible peripheral sensory lesion. Because communicating fibers may alter the visible pattern, exam findings should be interpreted as a distribution rather than as an absolutely isolated patch.
Its expected superficial course and distal sensory territory provide anatomical information for regional anesthesia planning around the foot and ankle. Awareness of the nerve helps clinicians consider whether the intended approach addresses the relevant cutaneous area and provides context when sensation remains after an intervention. The same anatomical knowledge supports interpretation of incomplete sensory coverage.
Surgical approaches can be planned with attention to the nerve's pathway beneath the skin and its distal branches. Preserving or accounting for these structures is clinically important because injury may produce numbness or neuropathic pain. Mapping the expected sensory territory before and after surgery can also help relate postoperative symptoms to a peripheral nerve distribution.
