What is a Nervous System?

Overview The nervous system is the collection of specialized cells responsible for maintaining an organism’s internal environment and coordinating the interaction of an organism with the external world—from the control of essential functions such as heart rate and breathing to the movement needed to escape danger. Parts of the Nervous System The vertebrate nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS...

Overview The parasympathetic nervous system is one of the two major divisions of the autonomic nervous system. This parasympathetic system is responsible for regulating many unconscious functions, such as heart rate and digestion. It is composed of neurons located in both the brain and the peripheral nervous system that send their axons to target muscles, organs, and glands. The “Rest and Digest” System Activation of the parasympathetic system tends to have a relaxing effect on the body,...

Overview The sympathetic nervous system—one of the two major divisions of the autonomic nervous system—is activated in times of stress. It prepares the body to meet the challenges of a demanding circumstance while inhibiting essential body functions—such as digestion—that are a lower priority at the moment. The “Fight or Flight” System As a student, you may have had the experience of walking into class and finding a surprise exam that you were not expecting. In the moment of realization, you...

Parkinson's disease has been related to the exposure to pesticides. Here we show a method to deliver pesticides using a gastric tube at the desired concentration and a method to analyze their effect in alpha-synuclein accumulation in the enteric nervous system.
FAQs
Combining electrical signals, imaging, and behavioral measurements provides complementary views of neural function. The resulting analysis can relate observed activity to neural structure, connectivity, and responses under defined conditions. This multimodal approach helps researchers avoid interpreting any single measurement in isolation and supports more coherent explanations of how neural systems process information.
Computational models connect quantitative measurements across biological levels, including cellular activity, network connectivity, and overall neural function. They provide a framework for interpreting how measured changes may relate to system behavior rather than treating each dataset separately. In bioengineering, these models also help guide the design and evaluation of engineered neural systems and neural devices.
Defined conditions make it possible to relate neural measurements to specific sensory, processing, or response contexts. By examining electrical, imaging, and behavioral data within those conditions, researchers can identify how neural function changes and distinguish normal operation from disease-related dysfunction. This contextual analysis is also important when judging whether a device or engineered model performs as intended.
A study generally begins by selecting the neural function and conditions to examine, followed by collecting relevant electrical, imaging, or behavioral measurements. Researchers then connect the observations with cellular activity and network connectivity through quantitative analysis and computational models. The resulting interpretation can guide evaluation of neural devices, engineered models, or possible therapeutic approaches.
Nervous system analysis supports the design and evaluation of brain-computer interfaces, neuroprostheses, diagnostic tools, and engineered neural models. Its measurements and models help determine how well these systems reflect or interact with neural function. The same analytical framework can clarify disease-related dysfunction, improve device performance, and contribute to more precise therapies.
By linking measured neural activity and connectivity with function, researchers can evaluate whether an interface or neuroprosthesis responds appropriately to neural information. Electrical signals, imaging, and behavioral outcomes provide evidence for that evaluation under defined conditions. The findings can guide device refinement and help assess performance in relation to the intended neural function.
