Note: This statement combines anatomy and/or ontology terms with phenotype quality terms to create a complete phenotype (EQ) statement. For detailed information on individual terms, click the hyperlinked term name.
Name: pretectum
Synonyms:
Definition: Multi-tissue structure that is the dorsal part of the diencephalon, caudal to the telencephalon, rostral to the midbrain optic tectum; the major sensory input to the pretectum is visual. From The Laboratory Fish.
Ontology: Anatomy Ontology [ZFA:0000418]
Name: lacks parts or has fewer parts of type
Synonyms: loss of
Definition: The bearer of this quality has_part < n of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type.

Name: dopaminergic neuron
Synonyms: dopaminergic neurons
Definition: A neuron that releases dopamine as a neurotransmitter.
