Description
Sensory processing (GO:0050893) is the set of neural operations by which an organism senses and interprets the dimensions of a sensory experience, including modality, location, intensity and affect. This Gene Ontology biological process term captures the integration of sensory input into meaningful percepts and responses, rather than the mere detection of a stimulus. Understanding sensory processing is central to systems neuroscience and to clinical research because differences in sensory processing are reported across multiple neurodevelopmental and psychiatric conditions. Research in autism spectrum disorder has been particularly influential, with neurophysiologic and behavioural studies documenting atypical responses to auditory, visual, tactile and other sensory modalities. Systematic reviews further link sensory processing differences to functional outcomes such as eating behaviours in autistic individuals. Beyond autism, meta-analytic evidence indicates that sensory processing difficulties are elevated in several psychiatric disorders, supporting a transdiagnostic view. The construct of sensory processing sensitivity has also been developed to describe individual differences in reactivity to sensory input in both humans and other species. For researchers, GO:0050893 provides a formal framework for annotating genes and pathways that contribute to sensory encoding, integration and interpretation. Because the term spans multiple levels of analysis, from receptor-level transduction to cortical integration and affective appraisal, it is useful for organizing genetic, physiological and behavioural data. This article summarizes the definition, biological context, key genes and research methods relevant to GO:0050893, based on published literature and the QuickGO definition.

What Is GO:0050893?
GO:0050893 sensory processing is defined by QuickGO as any neural process required for an organism to sense and interpret the dimensions of a sensory experience: modality, location, intensity and affect. In other words, it covers the neural steps that allow an organism not only to detect a stimulus but also to determine what kind of stimulus it is (modality), where it is (location), how strong it is (intensity) and how it is experienced effectively (affect). This definition distinguishes sensory processing from simpler sensory detection and places it within the broader context of perception and behaviour. The term is a biological process and has no listed synonyms in the QuickGO entry.
Why Is sensory processing Important in Cell Biology?
GO:0050893 is important because sensory processing is a fundamental bridge between the environment and behaviour, and its disruption is associated with significant clinical burden. Neurophysiologic and behavioural studies in autism spectrum disorder have shown that sensory processing differences are common and can affect daily functioning. A systematic review found associations between sensory processing and eating behaviours in autism, highlighting practical consequences. Meta-analytic evidence indicates that sensory processing difficulties are not limited to autism but are elevated across psychiatric disorders, supporting transdiagnostic relevance. Anxiety has been specifically linked to sensory processing within and beyond the autism spectrum. The neurobiology of sensory processing in autism has been reviewed in detail, pointing to alterations in cortical and subcortical circuits. In addition, sensory processing sensitivity has been proposed as a trait dimension relevant to individual differences and even veterinary behavioural medicine. Together, these findings make GO:0050893 a high-value term for researchers studying perception, neurodevelopment and psychiatric risk.

What Happens During sensory processing?
Sensory detection and modality encoding
In simple terms: First, the nervous system detects a stimulus and identifies what kind of stimulus it is.
Sensory processing begins with the detection of physical or chemical stimuli by sensory receptors and the encoding of stimulus modality. Neurophysiologic studies in autism have examined early sensory encoding using event-related potentials and other measures, revealing differences in the timing and amplitude of neural responses to auditory and visual stimuli. Reviews of sensory perception in autism describe how modality-specific pathways contribute to the initial representation of sensory input. The neurobiology of sensory processing in autism has been reviewed with attention to the role of cortical and subcortical circuits in modality encoding.
Location and spatial mapping
In simple terms: Next, the brain works out where the stimulus is coming from.
Localizing a sensory stimulus requires spatial mapping across sensory surfaces and external space. Studies of sensory processing in autism have reported atypicalities in spatial and temporal processing that may affect location judgments. Neurophysiologic findings reviewed by Marco et al. include differences in sensory gating and spatial attention that can influence how location information is processed. The neurobiology reviews further discuss how thalamocortical and corticocortical circuits contribute to spatial representation of sensory input.
Intensity coding and gain control
In simple terms: The brain also judges how strong the stimulus is and adjusts its sensitivity.
Intensity coding involves representing stimulus strength and adjusting neural gain. Sensory processing differences in autism often include atypical responses to stimulus intensity, such as hyper- or hyporeactivity. Neurophysiologic studies have examined gamma-band activity and other measures as correlates of intensity coding and gain control. Reviews of the neurobiology of sensory processing in autism discuss excitatory-inhibitory balance as a potential mechanism influencing intensity coding.
Affective and motivational interpretation
In simple terms: Finally, the brain attaches emotional meaning to the sensation, which can shape behaviour.
The affective dimension of sensory processing refers to how sensory experiences are interpreted emotionally and motivationally. Anxiety has been linked to sensory processing within and beyond the autism spectrum, suggesting that affective interpretation is closely tied to sensory reactivity. Sensory processing sensitivity research proposes that individual differences in affective reactivity to sensory input are measurable and relevant to behaviour. Systematic review evidence linking sensory processing to eating behaviours in autism further illustrates how affective and motivational interpretation of sensory input can influence complex behaviours.
Integration across modalities
In simple terms: The brain combines information from different senses into a unified experience.
Multisensory integration is a key component of sensory processing, allowing inputs from different modalities to be combined. Reviews of sensory perception in autism discuss evidence for atypical multisensory integration and its consequences for perception and behaviour. Neurophysiologic studies have examined cross-modal effects using electrophysiology. The broader neurobiology literature reviewed by Cheung et al. addresses how cortical networks support integration of sensory information.
Behavioural output and adaptation
In simple terms: The processed sensory information then guides actions and adjustments.
Sensory processing ultimately supports adaptive behavioural responses. In autism, sensory processing differences have been associated with eating behaviours and other functional outcomes. Anxiety research indicates that sensory processing can influence avoidance and other behavioural responses. Sensory processing sensitivity theory suggests that individual differences in processing can shape behavioural strategies across contexts.

How Is sensory processing Regulated?
Sensory processing is regulated at multiple levels, including excitatory-inhibitory balance, neuromodulatory systems and experience-dependent plasticity. Reviews of the neurobiology of sensory processing in autism discuss cortical and subcortical circuits, inhibitory interneuron function and synaptic plasticity as regulatory mechanisms. Neurophysiologic studies have examined gamma-band activity and event-related potentials as indices of regulatory dynamics during sensory processing. Anxiety-related research suggests that affective and arousal systems modulate sensory processing. Sensory processing sensitivity theory proposes that individual differences in reactivity reflect variation in regulatory thresholds. However, specific molecular regulators such as mTOR or the integrated stress response are not directly addressed in the provided citations, so they are not claimed here.

Marco et al. reviewed neurophysiologic findings in autism, including gamma-band activity and evoked potentials. These methods provide temporal resolution suitable for studying modality, intensity and timing of sensory responses.
Behavioural and psychophysical assessments
Behavioural tasks and psychophysical measures quantify sensory thresholds, discrimination and reactivity. Systematic reviews have used such measures to link sensory processing to eating behaviours in autism. Sensory processing sensitivity research also relies on self-report and behavioural measures.
Neuroimaging and circuit mapping
Functional magnetic resonance imaging and other neuroimaging approaches map brain regions involved in sensory processing. Reviews of the neurobiology of sensory processing in autism discuss cortical and subcortical circuits. These methods help identify networks supporting modality, location and affective dimensions.
Genetic and molecular approaches
Genetic association studies, animal models and molecular assays are used to identify genes contributing to sensory processing. Reviews discuss candidate genes and pathways in autism and related conditions. Meta-analytic work on psychiatric disorders supports the relevance of sensory processing across diagnoses.
How CRISPR Can Be Used to Study GO:0050893 sensory processing
Knockout
CRISPR knockout models can be used to test whether a candidate gene is required for sensory processing. For example, knocking out SHANK3 or CNTNAP2 in cell or animal models allows researchers to assess effects on sensory neuron function and behaviour. Knockout studies of FMR1 and MECP2 have been used to model sensory phenotypes in neurodevelopmental disorders.
Point Mutation
Point-mutation knock-in models introduce specific variants to study their impact on sensory processing. For genes such as SCN1A, point mutations can alter neuronal excitability and sensory responses. Such models help distinguish gain- or loss-of-function effects of individual variants.
Knock-in
Tagged knock-in approaches enable visualization or functional tagging of sensory processing-related proteins. Knock-in of fluorescent or epitope tags into genes such as GABRB3 or GRIN2B can reveal localization and dynamics in sensory circuits. These models support imaging and electrophysiological studies of sensory processing.
Overexpression
Overexpression models test whether increased levels of a gene product alter sensory processing. Overexpressing candidate genes such as BDNF or SLC6A4 can affect sensory reactivity and plasticity. These models complement knockout studies by revealing dosage-sensitive effects.
