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,...

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...

Neural stem cells (NSCs) refer to cells which can self-renew and differentiate into the three neural lineages. Here, we describe a protocol to determine NSC frequency in a given cell population using neurosphere formation and differentiation under clonal conditions.

Source: Heidbuechel, J. P., et al. Paramyxoviruses for Tumor-targeted Immunomodulation: Design and Evaluation Ex Vivo. J. Vis. Exp. (2019).This video demonstrates a cell-based assay to evaluate the target-specific immunomodulatory activity of a virally encoded bispecific T-cell engager (BTE). The BTE links tumor cells expressing a target receptor with T cells, triggering tumor lysis and enzyme release. A colorimetric readout, based on substrate conversion, indicates T-cell activation.

FAQs
Neural encoding can represent several stimulus dimensions simultaneously rather than relying on a single signal. Changes in firing rate may reflect intensity, while the timing of spikes, the activity of location-related neurons, and the duration of activity can convey additional information. Examining these dimensions together helps explain how neural populations distinguish changing sensory conditions.
Synaptic integration determines how inputs are combined before a neuron changes its firing. Excitatory and inhibitory influences can shape whether activity occurs, how often it occurs, and when it occurs. Because neurons receive converging signals, integration links incoming sensory information to the firing patterns ultimately observed across individual cells and larger neural populations.
A rate-based description emphasizes how frequently neurons fire, whereas a temporal description emphasizes when activity occurs. Neural encoding may also be distributed across populations, with information reflected in the combined activity of many neurons rather than one cell. Comparing these representations helps investigators determine whether a signal is carried by frequency, timing, or population structure.
Researchers examine neural activity alongside the information or condition being represented. They can evaluate changes in firing rate, timing, and activity across populations, then ask whether those changes track stimulus intensity, location, or duration. Relating the patterns to behavior provides a way to connect neural signals with perception, movement, memory, or decisions.
Brain-computer interfaces use recorded neural signals as inputs for interpreting or controlling external systems. Neural encoding is relevant because signal patterns must be related to information such as intended movement or another represented state. Computational models can formalize that relationship, while sensory prostheses draw on encoding principles when designing signals intended to convey sensory information.
Within neuroscience, encoding studies connect neural activity to functions supported by the nervous system. Sensory representations can be examined in relation to perception, movement-related activity alongside behavior, and patterns associated with internal processing in studies of memory and decision-making. This framework helps link measurable electrical signals to broader cognitive and behavioral outcomes.
