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.

Marine snail Aplysia californica has been widely used as a neurobiology model for the studies on cellular and molecular basis of behavior. Here a methodology is described for exploring the nervous system of Aplysia for the electrophysiological and molecular analyses of single neurons of identified neural circuitry.

2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...

Integration occurs when sensory inputs and descending commands converge on ganglion neurons. Synaptic transmission allows these neurons to combine incoming information rather than responding to a single signal in isolation. The resulting activity can generate patterned outputs directed toward muscles, glands, or internal organs, linking incoming conditions with coordinated visceral, motor, or segmental responses.
Patterned outputs organize neural activity into coordinated signals rather than isolated cellular responses. After ganglion neurons integrate converging inputs, their activity can be transmitted to muscles, glands, or internal organs in an organized manner. Examining these output patterns helps explain how local neural circuits coordinate body functions and how changes in input may alter the resulting response.
Synaptic transmission provides the communication step through which neurons influence one another within the circuit. It enables sensory information and descending commands to affect ganglion-neuron activity, which then contributes to signals sent toward effectors such as muscles, glands, or internal organs. Studying this process helps connect cellular communication with larger-scale reflexes and coordinated functions.
Researchers can examine how descending commands enter ganglion circuits and how processed activity is conveyed toward peripheral targets. Because abdominal ganglia provide a defined setting for tracing neural connectivity, they can support analysis of interactions between central and peripheral nervous systems. This perspective helps distinguish local circuit processing from influences imposed by descending neural control.
Their relatively defined anatomy makes abdominal ganglia useful for mapping the arrangement of neurons and their connections. Researchers can use this organization to examine which circuit elements receive sensory or descending input and how outputs are routed. Such analyses clarify nervous-system architecture while providing a structural basis for interpreting reflexes, motor coordination, and visceral regulation.
Studies of abdominal ganglia can address how local circuits generate reflexes, regulate body functions, and contribute to behavior. Investigators may focus on neural connectivity, the integration of converging inputs, or the cellular basis of patterned output. These systems are especially informative when researchers want to relate defined circuit structure to communication among neurons and coordinated activity in muscles, glands, or organs.
