The mammalian pharynx is a hollow muscular tube that participates in ingestion and respiration, and its size, shape, and stiffness can be altered by contraction of skeletal muscles that lie inside or outside of its walls. MRI was used to determine the interaction between pharyngeal pressure and selective stimulation of extrinsic tongue muscles on the shape of the rat nasopharynx. Pressure (-9, ...
INTRODUCTION AND OBJECTIVES Cardiac resynchronization therapy has been shown to be an option in the treatment of patients with congestive heart failure. The current indication for this treatment is based on clinical and electrocardiographic criteria, although echocardiography has also been shown to be a useful tool for the diagnosis of ventricular dyssynchrony. The aim of this study was to asse...
transcranial current stimulation (tcs) is a neuromodulation method in which the patient is exposed to a mild electric current (direct or alternating) at 1-2 ma, resulting in an increase or a decrease in the brain excitability. this modi.cation in neural activities can be used as a method for functional human brain mapping with causal inferences. this method might also facilitate the treatments ...
Direct electrical stimulation of the brain has emerged as a powerful treatment for multiple neurological diseases, and as a potential technique to enhance human cognition. Despite its application in a range of brain disorders, it remains unclear how stimulation of discrete brain areas affects memory performance and the underlying electrophysiological activities. Here, we investigated the effect...
Optical imaging of voltage-sensitive dyes in an isolated cerebellum preparation was used to study the spatiotemporal functional organization of the inhibitory systems in the cerebellar cortex. Responses to surface stimulation of the cortex reveal two physiologically distinct inhibitory systems, which we refer to as lateral and on-beam inhibition following classical terminology. Lateral inhibiti...
Transmission of auditory information from the medial geniculate body to the lateral nucleus of the amygdala is believed to be involved in the conditioning of fear responses to acoustic stimuli. This pathway exhibits LTP of electrically evoked field potentials after high frequency stimulation of the medial geniculate body. High frequency stimulation of the medial geniculate body also results in ...
We studied the effect of cholecystokinin (CCK-8) and yohimbine-alpha-2-adrenoreceptor antagonist administered locally into lateral reticular formation (LRF) on the bioelectrical response to the pain stimulation. The experiments were carried out on 8 conscious rabbits with bilaterally implanted electrodes into: motor-sensory cortex, ventro-postero-lateral thalamic nuclei, hippocampus and LRF. No...
Transcranial magnetic stimulation of the primary motor cortex (M1) is a promising treatment for chronic pain, but its mechanism action remains unclear. Competing dynamic causal models effective connectivity between M1 and medial lateral pain systems suggest direct input into insular, anterior cingulate cortex, parietal operculum. This supports hypothesis that analgesia produced from most likely...
