Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability. • The brain's ability to change begins with the growth of dendrites and axons, which effectively increases the structural...

Neuronal plasticity is an increasingly recognized, but insufficiently understood feature of the gastrointestinal (GI) tract. Here, in the example of human pancreatic disorders, we present an in vitro neuroplasticity assay for the study of neuronal plasticity in the GI tract at both morphological and functional level.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Using Optogenetics to Reverse Neuroplasticity and Inhibit Cocaine Seeking in Rats

The methods described here outline a procedure used to optogenetically reverse cocaine-induced plasticity in a behaviorally-relevant circuit in rats. Sustained low-frequency optical stimulation of thalamo-amygdala synapses induces long-term depression (LTD). In vivo optogenetically-induced LTD in cocaine-experienced rats resulted in the subsequent attenuation of cue-motivated drug seeking.

Long-term potentiation, synaptic remodeling, and network reorganization provide complementary mechanisms for changing neural function. Long-term potentiation helps reinforce activity-related synaptic patterns, while remodeling alters connections and reorganization redistributes functions across circuits. Together, these processes give engineered interventions a biological basis for reinforcing useful responses during training or rehabilitation.
Outcomes depend on how experience, injury, or stimulation is paired with targeted training and sensory input. These inputs provide activity that can shape synaptic and circuit-level responses rather than applying a completely separate signal. Selecting the relevant task or sensory context helps direct adaptation toward useful functional patterns in rehabilitation and human-machine interaction.
Network reorganization matters because useful function may depend on coordinated circuit changes, not only on a single synapse. When experience, injury, or stimulation alters functional responses, broader circuit adaptation can support new patterns of operation. This systems-level perspective helps engineers design interventions that work with changing neural activity in neuroprostheses, brain-computer interfaces, and rehabilitation systems.
A supported workflow pairs a person’s activity with feedback or therapeutic input, then uses targeted training or sensory input to reinforce the desired pattern. The essential design feature is the connection between what the user does and the engineered response. This pairing allows adaptive rehabilitation systems and stimulation technologies to engage activity-dependent synaptic and circuit changes.
These approaches are relevant when a system must accommodate changing neural function, including motor recovery, rehabilitation, learning, or direct human-machine interaction. Neuroprostheses and brain-computer interfaces can use the brain’s adaptive capacity as part of their design, while adaptive rehabilitation systems can adjust support around user activity. The shared goal is useful coordination between engineered input and neural change.
Evaluation can focus on whether training, sensory input, or stimulation produces improved motor recovery, learning, or interaction with a machine. The relevant outcome is not simply exposure to an intervention, but a useful change in functional response or coordinated behavior. In engineering research, these outcomes also clarify how designed systems can cooperate with the brain’s capacity to adapt.
