All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Zebrafish (Danio rerio) are widely used as an alternative vertebrate model organism in biomedical research. Their genetic similarity to humans, rapid development, and suitability for large-scale studies make them valuable tools...

Patch Clamp Electrophysiology

2023
Neuron cell membranes are populated with ion channels that control the movement of charge into and out of the cell, thereby regulating neuron firing. One extremely useful technique for investigating the biophysical properties of these channels is called patch clamp recording. In this method, neuroscientists place a polished glass micropipette against a cell and apply suction to form a high resistance seal. This process isolates a small “patch” of membrane that contains one or more ion channels.

This manuscript describes how to prepare intact dorsal root ganglia for patch clamp recordings. This preparation maintains the microenvironment for neurons and satellite glial cells, thus avoiding the phenotypic and functional changes seen using dissociated DRG neurons.

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Muscles of the Vertebral Column

The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers. Superficial Layer: The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
FAQs
The location and duration of occlusion determine which neural circulation is most affected. Clamping a vertebral vessel can alter posterior circulation, whereas placement near a supply route to the spinal cord may change spinal cord perfusion. Varying these parameters lets investigators produce distinct blood-flow challenges rather than treating every occlusion as equivalent.
Collateral circulation helps determine how strongly occlusion changes blood supply to neural tissue. Alternative vascular routes may lessen the effect of reduced flow, while limited compensation may increase the impact on posterior circulation or the spinal cord. Studying these differences helps researchers evaluate cerebrovascular regulation and understand why similar occlusions can produce different outcomes.
By creating a defined reduction or interruption of perfusion, vertebral clamping provides a controlled context for examining ischemic injury in neural tissue. Researchers can use the resulting blood-flow change to investigate how tissue responds to inadequate supply and to assess neuroprotective strategies intended to limit harmful effects associated with ischemic conditions.
Researchers select the vessel location and occlusion duration according to the circulation they want to examine. A protocol may target posterior circulation or spinal cord blood supply, then use the temporary change in perfusion to study a defined physiological or injury-related response. This design connects the mechanical intervention with a specific neural outcome.
The technique can reveal how neural blood supply responds when flow through a vertebral vessel is reduced or stopped. Comparing the resulting changes across different occlusion conditions may clarify the contribution of posterior circulation, spinal cord perfusion, and collateral pathways. These findings support broader investigation of how vascular regulation affects neural tissue.
Vertebral clamping is relevant when a neuroscience procedure requires controlled management of blood flow through a vertebral vessel or related structure. The approach can help examine how temporary occlusion affects posterior circulation or spinal cord perfusion, providing experimental context for evaluating surgical blood-flow control and its consequences for nearby neural tissue.
