Neuromodulation

Definition

Neuromodulation is the process by which a neurotransmitter or neuropeptide influences a group of neurons, leading to changes in their activity and behavior. This mechanism allows for the adjustment of neural circuits in response to varying physiological conditions, effectively modulating how signals are transmitted across synapses. In the context of neuroprosthetics, neuromodulation plays a crucial role in enhancing the function of devices designed to interface with the nervous system, paving the way for advanced therapeutic applications.
