Auditory stimulation and cardiac autonomic regulation
(Universidade de São Paulo (USP), Faculdade de Medicina, 2012-08-01)
Previous studies have already demonstrated that auditory stimulation with music influences the cardiovascular system. In this study, we described the relationship between musical auditory stimulation and heart rate ...
A randomized, double-blind clinical trial on the efficacy of cortical direct current stimulation for the treatment of major depression
(CAMBRIDGE UNIV PRESS, 2008)
Preliminary findings suggest that transcranial direct current stimulation (tDCS) can have antidepressant effects. We sought to test this further in a parallel-group, double-blind clinical trial with 40 patients with major ...
Effect of different intensities of transcranial direct current stimulation on postural response to external perturbation in patients with Parkinson’s disease
(SAGE Publications, 2020-11)
Background. Habituation of postural response to perturbations is impaired in people with Parkinson’s disease (PD) due to deficits in cortico-basal pathways. Although transcranial direct current stimulation (tDCS) modulate ...
Realimentação derivativa e modelo fuzzy Takagi-Sugeno paracontrole da articulação do joelho de pacientes paraplégicos com o uso de acelerômetros
(2011-06-01)
Feedback control systems have been used to move the muscles and joints of the limbs of paraplegic patients. The feedback signal, related to the knee joint angle, can be obtained by using an electrogoniometer. However, the ...
Effects of high-frequency transcranial magnetic stimulation on functional performance in individuals with incomplete spinal cord injury: Study protocol for a randomized controlled trial
(2017-11-06)
Background: Repetitive transcranial magnetic stimulation (rTMS) has been investigated as a new tool in neurological rehabilitation of individuals with spinal cord injury (SCI). However, due to the inconsistent results ...
Involvement of GABAergic mechanisms of the dorsal periaqueductal gray and inferior colliculus on unconditioned fear
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2009)
The fact that the dorsal periaqueductal gray (dPAG) and inferior colliculus (IC), together with superior colliculus, medial hypothalamus and amygdala, constitute the brain aversion system has been well-established. Stepwise ...
Transcranial Direct Current Stimulation Modulates Neuronal Networks in Attention Deficit Hyperactivity Disorder
(Springer, 2017-09)
Anodal transcranial direct current stimulation (tDCS) of the prefrontal cortex has been repeatedly shown to improve working memory (WM). Since patients with attention deficit hyperactivity disorder (ADHD) are characterized ...
Into the Island: A new technique of non-invasive cortical stimulation of the insula
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIERPARIS, 2012-12)
Study aim. - We describe a new neuronavigation-guided technique to target the posterior-superior insula (PSI) using a cooled-double-cone coil for deep cortical stimulation. Introduction. - Despite the analgesic effects ...
Interaction of epigallocatechin-gallate and chlorhexidine with Streptococcus mutans stimulated odontoblast-like cells: Cytotoxicity, Interleukin-1β and co-species proteomic analyses
(2021-11-01)
Objectives: The dentin therapeutic agent chlorhexidine has inflammatory and cytotoxic characteristics urging investigation of alternatives like the natural compound epigallocatechin-gallate. The aim is to verify the effect ...
Acute and chronic electrical activation of baroreceptor afferents in awake and anesthetized subjects
(Associação Brasileira de Divulgação Científica, 2009)
Electrical stimulation of baroreceptor afferents was used in the 1960's in several species, including human beings, for the treatment of refractory hypertension. This approach bypasses the site of baroreceptor mechanosensory ...
