Table 1 White matter connectivity terms and definitions

From: Neuroanatomical domain of the foundational model of anatomy ontology

Innervate

A connectivity relation where a neurite of one neuron synapses with a neurite or a region of the soma of another neuron or a region of a muscle cell or a gland cell.

Synapse_with

A connectivity relation where there is apposition between the presynaptic membrane of a neurite of one neuron and the postsynaptic membrane of one or more neurites of another neuron or a region of a muscle cell or a gland cell and some form of neurotransmission is evident between them.

Projects_to

A connectivity relation where individual axons comprising a fiber tract originating from one or more brain regions synapse_with neurites or somas of a collection of neurons located in one or more other brain regions. This relation may be synonymous with ‘terminate_in’.

Projects_from

A connectivity relation where individual axons comprising a fiber tract are parts of a collection of neurons located in one or more brain regions. This relation may be synonymous with ‘originate_in’.

Sends_output_to

A subproperty of project_to relation where neurotransmission is sent from one brain region to one or more other brain regions.

Receives_input_from

A subproperty of project_from relation where neurotransmission is received by one brain region from one or more other brain regions.

Has_pathway

A connectivity relation where a collection of neurons located in brain region A sends_output_to a collection of neurons located in B via axons comprising the fiber tract from brain region.
