Alogia
In psychology, alogia (Greek ἀ-, “without”, and λόγος, “speech”), or poverty of speech, is a general lack of additional, unprompted content seen in normal speech.

Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the brain and body.

Dopaminergic pathways
Dopaminergic pathways, sometimes called dopaminergic projections, are the sets of projection neurons in the brain that synthesize and release the neurotransmitter dopamine.

Executive functions
Executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that are necessary for the cognitive control of behavior: selecting and successfully monitoring behaviors that facilitate the attainment of chosen goals.

Nigrostriatal pathway
The nigrostriatal pathway or the nigrostriatal bundle (NSB), is a dopaminergic pathway that connects the substantia nigra pars compacta (SNc) with the dorsal striatum (i.e., the caudate nucleus and putamen).

Prefrontal cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe.

Psychosis
Psychosis is an abnormal condition of the mind that results in difficulties telling what is real and what is not.

Reduced affect display
Reduced affect display, sometimes referred to as emotional blunting, is a condition of reduced emotional reactivity in an individual.

Schizophrenia
Schizophrenia is a mental disorder characterized by abnormal social behavior and failure to understand reality.

Tuberoinfundibular pathway
The tuberoinfundibular pathway refers to a population of dopamine neurons that project from the arcuate nucleus (the "infundibular nucleus") in the tuberal region of the hypothalamus to the median eminence.

Ventral tegmental area
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
