Therapies ... -
Responses of primate LGN cells to moving stimuli involve a constant background modulation by feedback from area MT
Jones, Helen E.; Andolina, Ian M.; Grieve, Kenneth; Wang, W.; Salt, T.E.; Cudeiro, Javier; Sillito, Adam M. (Elsevier, 2013-05-03)[Abstract] The feedback connections from the cortical middle temporal (MT) motion area, to layer 6 of the primary visual cortex (V1), have the capacity to drive a cascaded feedback influence from the layer 6 cortico-geniculate ... -
Spatiotemporal gait patterns during overt and covert evaluation in patients with Parkinson’s disease and healthy subjects: is there a hawthorne effect?
Robles-García, Verónica; Corral Bergantiños, Yoanna; Espinosa, Nelson; Jácome, M. A.; García-Sancho, Carlos; Cudeiro, Javier (Human Kinetics, 2015)[Abstract] Parkinson's disease (PD) and aging lead to gait impairments. Some of the disturbances of gait are focused on step length, cadence, and temporal variability of gait cycle. Under experimental conditions gait can ... -
Spectroscopic measurement of cortical nitric oxide release induced by ascending activation
Espinosa, J.; Cudeiro, Javier; Mariño Alfonso, Xurxo (Elsevier, 2014-11-25)[Abstract] The transition from sleep to the awake state is regulated by the activation of subcortical nuclei of the brainstem (BS) and basal forebrain (BF), releasing acetylcholine and glutamate throughout the cortex and ... -
Static magnetic fields reduce epileptiform activity in anesthetized rat and monkey
Rivadulla, Casto; Aguilar, Juan; Coletti, Marcos; Aguila, Jordi; Prieto, Sandra; Cudeiro, Javier (Nature, 2018-10-30)[Abstract] Increasing evidence indicates that static magnetic fields (SMF) reduce cortical activity in both human and animal models.
