Sensorem

Sensorem is a term used in theoretical discussions of sensory systems and neuromorphic engineering to denote a localized, modular unit responsible for detecting a specific type of stimulus and initiating neural coding. The concept is not a standard anatomical label but a functional construct intended to capture the common features shared by receptor cells and their immediate signal processing.

In biological contexts, a sensorem can be described as the minimal functional bundle consisting of a receptor mechanism and the first transduction steps that convert physical or chemical stimuli into neural signals. In artificial systems, sensorem refers to a single sensor module that performs detection and encoding, often including an analog-to-digital conversion and initial feature extraction, before transmission to downstream processing units.

Core properties include modality specificity, transduction efficiency, adaptation dynamics, and encoding that preserves timing and intensity information. When arranged in an array, sensorem units can support population coding across modalities.

Relation to established terms: sensorem overlaps with receptor and sensory neuron concepts but is used as a higher-level, modular abstraction. In neuromorphic design, sensorem modules describe building blocks of artificial perception.

Usage and status: the term appears in theoretical discussions and speculative design documents. It is not part of formal medical or anatomical nomenclature.
