    • Acetylcholinesterase activity in the pons and medulla oblongata of rats after chronic electroconvulsive shock 

      Camarini, Rosana [UNIFESP]; Venditti, Marco Antonio Campana [UNIFESP] (Associação Brasileira de Divulgação Científica, 1997-10-01)
      An imbalance between cholinergic and noradrenergic neurotransmission has been proposed for the etiology of affective disorders. According to this hypothesis, depression would be the result of enhanced cholinergic and reduced ...

    • BRAINSTEM AREAS ACTIVATED BY INTERMITTENT APNEA in AWAKE UNRESTRAINED RATS 

      Ferreira, C. B. [UNIFESP]; Schoorlemmer, G. H. [UNIFESP]; Rossi, M. V. [UNIFESP]; Takakura, A. C.; Barna, B. F.; Moreira, T. S.; Cravo, S. L. [UNIFESP] (Elsevier B.V., 2015-06-25)
      We investigated the role of the autonomic nervous system to cardiovascular responses to obstructive apnea in awake, unrestrained rats, and measured expression of Fos induced by apnea in the brainstem. We implanted a tracheal ...

    • CATALASE INHIBITION INTO the FOURTH CEREBRAL VENTRICLE AFFECTS BRADYCARDIC PARASYMPATHETIC RESPONSE TO INCREASE in ARTERIAL PRESSURE WITHOUT CHANGING the BAROREFLEX 

      Valenti, Vitor E. [UNIFESP]; De Abreu, Luiz Carlos; Sato, Monica A.; Fonseca, Fernando L. A.; Perez Riera, Andres R.; Ferreira, Celso [UNIFESP] (Imperial College Press, 2011-03-01)
      Exogenous catalase influences neural control of cardiovascular system; however, we do not know yet if its inhibition into the fourth cerebral ventricle (4(th) V) influences baroreflex regulation. We evaluated the effects ...

    • Expression of Phox2b by brainstem neurons involved in chemosensory integration in the adult rat 

      Stornetta, Ruth L.; Moreira, Thiago S.; Takakura, Ana C.; Kang, Bong Jin; Chang, Darryl A.; West, Gavin H.; Brunet, Jean Francois; Mulkey, Daniel K.; Bayliss, Douglas A.; Guyenet, Patrice G. (Soc Neuroscience, 2006-10-04)
      Central congenital hypoventilation syndrome is caused by mutations of the gene that encodes the transcription factor Phox2b. the syndrome is characterized by a severe form of sleep apnea attributed to greatly compromised ...

    • Galanin Is a Selective Marker of the Retrotrapezoid Nucleus in Rats 

      Stornetta, Ruth L.; Spirovski, Darko; Moreira, Thiago S. [UNIFESP]; Takakura, Ana C. [UNIFESP]; West, Gavin H.; Gwilt, Justin M.; Pilowsky, Paul M.; Guyenet, Patrice G. (Wiley-Blackwell, 2009-01-20)
      The rat retrotrapezoid nucleus (RTN) contains CO(2)-activated neurons that contribute to the central chemoreflex and to breathing automaticity. These neurons have two known markers, the transcription factor Phox2b and ...

    • Rapid eye movement sleep deprivation induces an increase in acetylcholinesterase activity in discrete rat brain regions 

      Venditti, Marco Antonio Campana [UNIFESP]; Camarini, Rosana [UNIFESP] (Associação Brasileira de Divulgação Científica, 2001-01-01)
      Some upper brainstem cholinergic neurons (pedunculopontine and laterodorsal tegmental nuclei) are involved in the generation of rapid eye movement (REM) sleep and project rostrally to the thalamus and caudally to the medulla ...
