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: preoptic area
Synonyms: area praeoptica, area preoptica, preoptic region
Definition: Area of the forebrain anterior to the posterior tuberculum and the hypothalamus and ventral to the ventral thalamus. See Figure 7, p. 34 in Atlas of Early Zebrafish Brain Development.
Ontology: Anatomy Ontology [ZFA:0000470]
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.
