Alteration of cortical excitability in patients with fibromyalgia
(ELSEVIER SCIENCE BV, 2010)
We assessed cortical excitability and intracortical modulation systematically, by transcranial magnetic stimulation (TMS) of the motor cortex, in patients with fibromyalgia. In total 46 female patients with fibromyalgia ...
Blockade of spreading depression in chronic epileptic rats: Reversion by diazepam
(Elsevier B.V., 1997-04-01)
Following pilocarpine-induced status epilepticus, rats become chronically epileptic showing 2-3 spontaneous recurrent seizures per week. the aim of this work was to verify the characteristics of spreading depression (SD) ...
Modeling of post-stroke stimulation of cortical tissue
(2018)
Following a stroke, cortical networks in the penumbra area become fragmented and partly deactivated. We develop a model to study the propagation of waves of electric potential in the cortical tissue with integro-differential ...
Rapid eye movement sleep deprivation induces changes in the high-affinity binding of [H-3]-ouabain to the rat cortical membranes
(Elsevier B.V., 2006-03-27)
Rapid eye movement sleep (REMS) suppresses seizures. On the other hand, REMS deprivation (REMSD) increases brain susceptibility to seizures. Sodium-postassium/ATPase is involved in the control of brain excitability. Ouabain, ...
Increased variability of motor cortical excitability to transcranial magnetic stimulation in migraine: a new clue to an old enigma
(SPRINGERNEW YORK, 2012)
Increased, decreased or normal excitability to transcranial magnetic stimulation (TMS) has been reported in the motor (M1) and visual cortices of patients with migraine. Light deprivation (LD) has been reported to modulate ...
Ação da glutamina no cérebro em desenvolvimento: estudo comportamental, eletrofisiológico e imunohistoquímico em ratos jovens e adultos submetidos a diferentes condições de lactação
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Nutricao, 2017)
Input normalization by global feedforward inhibition expands cortical dynamic range
(Nature Publishing Group, 2009-11)
The cortex is sensitive to weak stimuli, but responds to stronger inputs without saturating. The mechanisms that enable this wide range of operation are not fully understood. We found that the amplitude of excitatory ...
Interação nutrição-agentes anestésicos: efeitos eletrofisiológicos sobre a depressão alastrante cortical em ratos adultos
(UNIVERSIDADE FEDERAL DE PERNAMBUCOUFPEBrasilPrograma de Pos Graduacao em Administracao, 2016)
Nutrição, hormônios ovarianos e desenvolvimento cerebral: análise eletrofisiológica pela depressão alastrante cortical
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Bioquimica e Fisiologia, 2016)
