Cuneiform nucleus stimulation modifies laryngeal activity and subglottic pressure in rats
Carrillo-Franco, Laura; López-González, Manuel Víctor; González-García, Marta; Casermeiro-García, Claudia; Díaz-Casares, Amelia; [et al.] (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
Carrillo-Franco, Laura; López-González, Manuel Víctor; González-García, Marta; Casermeiro-García, Claudia; Díaz-Casares, Amelia; [et al.] (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 dorsolateral periaqueductal grey (dlpag) in spontaneously breathing anaesthetized rats
González-García, Marta; López-González, Manuel Víctor; Carrillo-Franco, Cristina; Carrillo-Franco, Laura; Barbancho-Fernández, Miguel Angel; [et al.] (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 ... -
Does the midbrain dorsolateral periaqueductal grey have direct connections with the pontine A5 region? A neuropharmacologic and electrophysiological study
González-García, Marta; López-González, Manuel Víctor; Díaz-Casares, Amelia; Peinado-Aragonés, Carlos Antonio; Barbancho-Fernandez, Miguel Angel; [et al.] (2018-07-16)This study has been performed in spontaneously breathing anesthetised rats. We have analysed the possible interactions between the midbrain dorsolateral periaqueductal grey matter (dlPAG) and the pontine A5 region. Electrical ... -
Dorsolateral periaqueductal grey matter and pontine A5 region connectivity: a neuropharmacologic and electrophysiological study
Díaz-Casares, Amelia; López-González, Manuel Víctor; Barbancho-Fernandez, Miguel Angel; Peinado Aragonés, Carlos Antonio; Dawid-Milner, Marc Stefan; [et al.] (2018-09-25)In this study, carried out in spontaneously breathing anesthetised rats, we have analysed the relevance of the interactions between the dorsolateral periaqueductal grey matter (dlPAG) and the A5 region, and how this ... -
Dorsolateral Periaqueductal Grey Matter stimulation modifies laryngeal activity and subglottic pressure in spontaneously breathing anaesthetized rats
González-García, Marta; López-González, Manuel Víctor; Carrillo-Franco, Laura; Casermeiro-García, Claudia; Díaz-Casares, Amelia; [et al.] (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 ... -
Eficacia de la Estimulación Magnética Repetitiva en la Depresión Crónica Resistente a Fármacos

González-García, Marta; López-González, Manuel Víctor; Carrillo-Franco, Laura; Carrillo-Franco, Cristina; Dawid-Milner, Marc Stefan (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

Insulin-like growth factor II neuroprotective effects against mitochondrial-oxidative and neuronal damage induced by CORT and MPP+ in dopaminergic neurons
Claros-Gil, Silvia; Cabrera, Pablo; Valverde, Nadia; Romero-Zerbo, Silvana Y.; Lara, Estrella; [et al.] (2022-07-12)Aims: Parkinson’s disease (PD) affects 1–3% of the population aged over 65. Stress seems to contribute to PD neuropathology, probably by dysregulation of the hypothalamic–pituitary–adrenal axis. Key factors are oxidative ... -
