Isolation of Cells from Sensory Ganglia

This video demonstrates the isolation of cells from the sensory ganglia of mice. Ganglia are subjected to enzymatic digestion to dissolve the extracellular matrix. Single cells are then collected via filtering through a cell strainer followed by density gradient centrifugation for debris removal. Finally, washing and centrifugation are done to collect the isolated cells for future analysis.

What is a Sensory System?

Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position. Sensory systems include the visual, auditory, gustatory (taste), olfactory (smell), somatosensory (touch, pain, temperature, and proprioception), and vestibular...

Analysis of vestibular hair cell function is complicated by their location deep within the hardest part of the skull, the petrous temporal bone. Most functional hair cell studies have used acutely isolated hair cells. Here we describe a semi-intact preparation of mouse vestibular epithelium for electrophysiological and two-photon microscopy studies.

Source:Tracey A. Milligan, MD; Tamara B. Kaplan, MD; Neurology, Brigham and Women's/Massachusetts General Hospital, Boston, Massachusetts, USA A complete sensory examination consists of testing primary sensory modalities as well as cortical sensory function. Primary sensory modalities include pain, temperature, light touch, vibration, and joint position sense. Sensation of the face is discussed in the videos Cranial Nerves Exam I and II, as are the special senses of smell, vision, taste, and...
FAQs
By reducing visual, auditory, and tactile signals, the chamber lowers the amount of externally driven information reaching the brain. Researchers can then examine perception, attention, and body awareness under conditions where internally generated activity becomes easier to study in relation to ordinary sensory processing. This contrast helps clarify how the brain organizes experience when external input is limited.
Each condition limits a different source of stimulation. Darkness reduces visual input, sound reduction limits auditory signals, and temperature-controlled conditions help minimize thermal distractions. A buoyant saline solution supports the body while reducing ordinary tactile demands. Combining these elements produces a more comprehensive reduction of sensory information than restricting only one sensory channel.
With fewer incoming signals, the brain must adjust to a markedly changed sensory environment. Studying this adaptation can reveal how neural processing responds when ordinary stimulation is reduced and how perception, body awareness, attention, or time perception may change. These observations also help investigators distinguish responses associated with external events from experiences arising within the nervous system.
A protocol may combine darkness, reduced sound, controlled temperature, and a buoyant saline solution. These conditions target visual, auditory, thermal, tactile, and bodily influences at the same time. The specific combination allows investigators to control the sensory environment more systematically and to relate observed changes in perception or consciousness to the reduction of particular external signals.
The approach can support studies of attention, body awareness, time perception, consciousness, and neural adaptation. It also provides a controlled context for examining stress, relaxation, and altered perceptual experiences. Because ordinary environmental stimulation is reduced, researchers can focus on how the brain constructs or regulates experience when fewer external cues are available.
Sensory isolation protocols create controlled conditions in which investigators can examine stress- or relaxation-related responses alongside changes in perception and consciousness. The reduced sensory environment helps separate effects associated with external stimulation from experiences occurring during the protocol. This makes the approach relevant for studying how restricted input relates to relaxation, stress, and altered perceptual states.
