Psychology of The Human Voice
Several brain areas have been proved to be activated and or involved in vocalization and laughter: the dorsolateral frontal cortex, supplementary motor and auditory areas, the lateral hypothalamus, anterior cingulated nucleus, right putamen, left insula, parietal operculum, amygdale, limbic areas and right cerebellum.
Abstract
Human voice is the sound produces when the air from the lungs vibrates the vocal chords in the throat. The larynx is the complex organ involves in this mechanism of phonation, breathing and swallowing. They involved a common laryngeal and esophagus integrative system which modulate the respiratory control, thought the swallowing function is not primarily controlled under cortical brain mechanism [1]. In nonhuman primates, vocalizations are controlled by subcortical regions [2]. Studies in monkeys have shown the cingulated cortex, periaquaductal/ gray pons and brain stem nuclei are involved in vocalization system. In humans affected by strokes in speech brain areas or with in vivo studies, several brain areas have been proved to be activated and or involved in vocalization and laughter: the dorsolateral frontal cortex, supplementary motor and auditory areas, the lateral hypothalamus, anterior cingulated nucleus, right putamen, left insula, parietal operculum, amygdale, limbic areas and right cerebellum [1-4]. In speech human articulation, the ventral pre and post central gyri are activated in the lateral sensorimotor (Rolandic) cortex [5].
