Learning new stimulus-response associations engages a wide range of neural processes which are ultimately reflected in changing spike output of individual neurons. Here we describe a behavioral protocol allowing for the continuous registration of single-neuron activity while animals acquire, extinguish, and reacquire a conditioned response within a single experimental session.

Understanding the function of the vertebrate central nervous system requires recordings from many neurons because cortical function arises on the level of populations of neurons. Here we describe an optical method to record suprathreshold neural activity with single-cell and single-spike resolution, dithered random-access scanning. This method records somatic fluorescence calcium signals from up to 100 neurons with high temporal resolution. A maximum-likelihood algorithm deconvolves the...

Here, we present a combinatorial approach for classifying neuronal cell types prior to isolation and for the subsequent characterization of single-cell transcriptomes. This protocol optimizes the preparation of samples for successful RNA Sequencing (RNA-Seq) and describes a methodology designed specifically for the enhanced understanding of cellular diversity.
FAQs
Biochemical signaling allows an environmental stimulus to alter activity inside an individual cell, while feedback networks can reinforce or regulate that altered state. This interaction helps connect an earlier exposure with a later response rather than producing an isolated reaction. Studying these linked processes reveals how cells coordinate movement, growth, or stress responses without requiring a nervous system.
Changes in gene expression can convert a temporary stimulus into a physiological state that persists after the original exposure. Depending on how long that state remains, the cell may show short-term or long-lasting effects when it encounters a later condition. This provides a molecular basis for investigating cellular memory and how past environments influence future behavior.
Single-cell learning does not depend on neurons or a centralized nervous system. Instead, an individual cell uses biochemical signaling, feedback, and gene-expression changes to alter later responses. This comparison helps biology examine whether learning-like properties can arise from basic cellular processes, while also providing context for research on the possible origins of cognition.
A previous environmental stimulus can leave a physiological state that influences how the cell responds to a subsequent condition. The effect may be brief or persist for longer periods, depending on the cellular changes associated with that exposure. Examining this timing helps researchers connect environmental history with later decisions involving movement, growth, and stress responses.
Researchers can examine how an individual cell responds to an environmental stimulus and then assess whether a later response differs after that earlier exposure. Microorganisms and other individual cells provide useful systems for connecting exposure history with changes in movement, growth, or stress responses. Such comparisons help identify cellular states that may represent memory or adaptation.
These studies can show whether a cell’s previous exposure changes a later physiological response. Relevant outcomes include altered movement, growth, or reactions to stress, along with evidence of short- or long-lasting cellular states. Together, these observations clarify how individual cells adapt and make responses that contribute to broader patterns in biology.
Microbial behavior can be examined as the combined result of independently responding cells whose histories influence later actions. In synthetic biology, the same principles provide a conceptual basis for considering how biochemical signaling, feedback networks, and gene expression might produce controllable cellular states. These applications connect individual-cell responses with engineered systems and population-level behavior.
Single-cell learning shows that learning-like cellular responses can be studied through molecular processes rather than assumed to require a nervous system. By examining memory, adaptation, and decision-making in individual cells, biology can investigate how these capabilities may arise from simpler systems. The work therefore provides context for understanding cognition as a process with possible cellular foundations.
