The application of a classical fear conditioning behavioral paradigm for auditory prosthetic research in rats is described. This paradigm provides a mechanism for identifying both detection of, and discrimination between, distinct acoustic and electrical stimuli using heart-rate as an outcome measure.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Long-term memory is a critical feature of human cognition, and it has been a prominent focus of research in experimental psychology. Many paradigms designed to tap long-term memory rely on asking participants to learn or study content, then test memory about that content. This is a good approach if one wants to understand how memory supports educational achievement, for example, where explicit study is part of the process. But,...

Inducing Axonal Varicosities with a Micromechanical Stimulus on Neurons

2025
This video demonstrates the induction of axonal varicosities by applying micromechanical stimulus on neurons. The system comprises a micropipette attached to a syringe containing buffer via tubing. Using a micromanipulator, the micropipette is positioned above the neurons. Fluid pressure is then applied to induce varicosities in axons.

Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing. Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

This protocol describes key steps involved in assessing the sensitivity of the brain of one person to the stimulus processing of a close other by selecting pairs of partners, recording their electroencephalogram (EEG) simultaneously and computing their event-related brain potentials (ERPs).
FAQs
Encoding can be distributed across changes in firing rate, spike timing, and coordinated activity rather than relying on one neural feature. Firing rate captures variation in activity level, while spike timing preserves when signals occur; coordination reflects population-level organization. Considering these components together can clarify how sensory information supports behavioral responses.
Stimulus intensity, duration, and temporal variation all influence the quality of sensory representation. Intensity concerns the strength of environmental information, duration describes how long it is present, and temporal variation captures changes over time. Examining these properties together helps explain why some signals are represented more effectively than others.
Rapidly changing events require sensory representations that preserve relevant temporal variation. Encoding rates provide a way to examine how neural signals track those changes and whether the resulting information remains useful for behavior. This perspective helps identify limits on detecting signals, distinguishing events, and selecting responses when environmental information changes quickly.
A useful analysis links three elements: the physical properties of a stimulus, the associated neural signals, and the organism’s observable behavior. Researchers can compare how changes in intensity, duration, or temporal variation correspond to neural activity and behavioral outcomes. This approach connects sensory processing with detection, discrimination, and response selection.
Measurements of encoding rates can help identify limits on perception and decision-making by showing how environmental information is represented before a behavioral response occurs. Comparing neural dynamics with observable choices or actions can indicate whether differences in sensory representation accompany differences in detecting signals, distinguishing events, or selecting appropriate responses.
Comparing encoding rates across conditions can reveal how sensory processing relates to changes in behavior. Differences in firing rate, spike timing, or coordinated activity may accompany altered abilities to detect signals, distinguish rapidly changing events, or choose responses. Such comparisons also support broader analyses of sensory processing across conditions without treating behavior as separate from neural dynamics.
