Effects of water on cortical excitability in humans
European Journal of Neuroscience, 2002AbstractThe effects of water on cortical excitability, measured using magnetoencephalographic recordings, were investigated in a sample of 19 healthy volunteers in a double‐blind, placebo experiment comparing water with saline solution. Spontaneous magnetoencephalogram as well as auditory‐evoked magnetic fields were recorded before and after the ...

Altered cortical excitability in anorexia nervosa
Neurophysiologie Clinique/Clinical Neurophysiology, 2014Recent EEG and positron emission tomography (PET) studies have reported hyperactivation of the right hemisphere in anorexia nervosa (AN). The aim of the present study was to test this notion by examining cortical excitability in subjects with AN using transcranial magnetic stimulation (TMS).We investigated thirteen patients meeting the DSM IV ...

Cortical Excitability Changes Following Transcallosal Afferent Excitation
1971In cats anesthetized with sodium pentobarbital, it has been found that stimulation of the corpus callosum or the contralateral homotopic point has an inhibitory effect on potentials evoked by tone bursts in the auditory area of the cortex [1]. In results obtained from the “encephale isole” preparation, however, there was additionally a facilitatory ...

Cortical excitability and post-stroke recovery
Biochemical Society Transactions, 2009Stroke is the leading cause of adult disability. Recent studies show that the brain can engage in a limited process of neural repair after stroke: re-mapping of sensory and motor function and sprouting of new connections in peri-infarct cortex surrounding the stroke.

Gauging and controlling excitability in cortical disorders
Current Opinion in NeurologyPurpose of review Cortical excitability, defined as the cortex's responsiveness to incoming stimuli, is a fundamental concept in neuroscience and a targetable mechanism for controlling brain dysfunctions such as epilepsy, as well as other neurological and psychiatric disorders.

Gravitational Stress: Changes in Cortical Excitability
Science, 1964Evoked responses, recorded from the visual cortex, are enhanced during positive (head to tail) acceleration, and during cerebral hypotension induced by hemorrhage. The phenomenon observed during positive acceleration may therefore be due, at least in part, to its hypotensive effect, but the increased somatic stimulation must also be considered.
