Neurónek

Neurónek is a term found in some Slavic-language sources and informal discussions to denote a small neuron or neuron-like cell. It is not an established category in standard neuroscience nomenclature, and its usage can vary between sources.

In many descriptions, neurónek refers to neurons with smaller soma and more compact dendritic and axonal arborizations than typical projection neurons. They may have shorter axons and dendrites, enabling higher packing density in local circuits such as cortical or hippocampal networks. Morphological features often include relatively simple branching patterns and, in some contexts, higher input resistance compared with larger neurons.

Functionally, neurónek are typically described as participating in local processing within microcircuits. They can contribute to feedforward or feedback inhibition, regulate the timing and gain of nearby neurons, and support synchronization within a circuit. Because of their small size, they are frequently associated with interneuronal roles, but the label can also be used more loosely for small excitatory cells in certain regions.

Development and plasticity follow general neuronal patterns: neurónek arise from neural progenitor cells, migrate to their destinations, and differentiate under genetic and environmental cues. Their synapses undergo activity-dependent plasticity, influencing how they integrate inputs and modulate network activity, even though their compact morphology may emphasize local rather than long-range signaling.

Terminology and context: since neurónek is not universally standardized, precise meaning depends on the source. In formal discussions, more specific terms such as interneuron or granule cell are usually preferred. See also neuron, interneuron, cortical microcircuit.
