The Research Domain Criteria (RDoC) framework provides a research approach that views mental health in the context of major domains of basic human neurobehavioural functioning.

The olfactory system detects airborne odor molecules in the nasal cavity and transmits this information to the olfactory bulb. From there, signals are relayed to several brain regions involved in smell perception, memory, emotion, and behaviour.

The gustatory system detects taste stimuli on the tongue and relays this information through brainstem and thalamic pathways to the gustatory cortex.

Movement is controlled by a network of brain and spinal cord structures that work together to plan, initiate, coordinate, and execute actions.

Signals from the primary motor cortex travel through upper motor neurons to lower motor neurons, which directly innervate muscle fibres and produce muscle contraction.
