Cuneiform nucleus and Dorsomedial Hypothalamic nucleus and Perifornical area in the control of laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats.
(2023)Background: The DMH-PeF and the CnF have been involved in sympathetic activity due their connectivity with several nuclei involved in cardiorespiratory control. In previous studies we have demonstrated a functional ... -
Cuneiform nucleus stimulation modifies laryngeal activity and subglottic pressure in rats
(2022-09-20)The Cuneiform nucleus (CnF) of the mesencephalon has afferent and efferent connections with different regions of the CNS involved in cardiorespiratory control, i.e. dorsolateral part of the Periaqueductal Gray matter (dlPAG) ... -
Cuneiform nucleus stimulation modifies laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats
(2022-07-12)Background Abduction and adduction of the vocal folds are performed by two populations of motoneurons located in the caudal portion of the nucleus Ambiguus (nA). In the rat, the loose formation of the nA contains motoneurons ... -
Design and implementation of a method to study laryngeal resistance during the stimulation of cuneiform nucleus (CnF) in spontaneously breathing anaesthetized rats
(2021-11)The aim of this study was to characterize the electrophysiological relationships between the CnF and those pontine-medullary neuronal circuits to understand their role in laryngeal control and its effect on vocalization. ... -
Design and implementation of a method to study laryngeal resistance during the stimulation of dorsolateral periaqueductal grey (dlpag) in spontaneously breathing anaesthetized rats
(2019-09-11)Stimulation of the dorsolateral periaqueductal gray matter (dl-PAG) in rats evokes a cardiorespiratory response characterised by an increase of blood pressure, heart rate and respiratory frequency. In previous studies we ... -
Dorsolateral Periaqueductal Grey Matter in the control of laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats.
(2023)The stimulation of the dlPAG produces vocalization. The nRA turn passive into active expiration modifying the activity of laryngeal motoneurons located in the nA. We have shown that cPB and A5 Region are involved in changes ... -
Dorsolateral Periaqueductal Grey Matter stimulation modifies laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats
(2022-07-12)Abduction and adduction of the larynx allow changes in airflow necessary for the vibration of the vocal folds and emission of voice. It is known that stimulation of the Periaqueductal Gray matter (PAG) and nucleus retroambiguus ... -
Effects of stimulation of cuneiform nucleus and the dorsomedial Hypothalamic nucleus and Perifornical area on the mechanisms involved in the control of laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats.
(2023-07)The dorsomedial Hypothalamic nucleus and Perifornical area (DMH-PeF) and the mesencephalic Cuneiform nucleus (CnF) have been involved in sympathetic activity due their connectivity with several nuclei involved in ... -
Hypothalamic and mesencephalic regions involved in the control of laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats
(2019-07-12)Changes of laryngeal caliber allow changes in airflow which are necessary for the vibration of the vocal folds and emission of voice. It is known that stimulation of the Periaqueductal Gray matter (PAG) and nucleus ... -
Impact of Dorsolateral Periaqueductal Grey Matter stimulation in laryngeal activity and subglottic pressure in rats
(2022-09-20)The stimulation of the dorsolateral Periaqueductal Gray matter (dlPAG) produces an increase in sympathetic tone that includes an increase in cardiorespiratory parameters (blood pressure, heart rate and respiratory frequency). ... -
Laryngeal effects of stimulation of the cuneiform nucleus (CnF) in spontaneously breathing anaesthetized rats
(2021-11)The aim of this study was to characterise the relationship between mesencephalic-pontine neuronal circuits to understand their role in laryngeal control and its effect on vocalization. Methods: Experimental studies were ... -
Laryngeal effects of stimulation of the dorsolateral Periaqueductal Grey Matter in spontaneously breathing anaesthetized rats
(2023-07)The stimulation of the Periaqueductal Gray matter (PAG) and nucleus retroambiguus (nRA) produces vocalization. A high expression of FOXP2 protein at mesencephalic (PAG) and pontine regions involved in cardiorespiratory ... -
Laryngeal effects of stimulation of the dorsomedial hypothalamic nucleus and perifornical area in spontaneously breathing anaesthetized rats
(2019-09-11)Background: Stimulation of the dorsomedial hypothalamic nucleus and perifornical area (DMH-PeF) in rats evokes a cardiorespiratory response characterised by an increase in blood pressure, heart rate and respiratory frequency. ...
