Exempel på electroencephalogram

• The interplay between theta and alpha oscillations in the human electroencephalogram reflects the transfer of information between memory systems.

• In addition, this intermediate level of recording could help to bridge the gap between unit activity in animals and scalp electroencephalogram in humans.

• One additional goal is the attempt to establish new relationships between objective study findings (electroencephalograms) and biological disorders underlying the psychoses.

• But it is entirely conceivable that this increment might be detectable in the electroencephalogram which accompanies the continuous activity of the brain.

• An electroencephalogram showed periodic lateralized epileptiform discharges on the posterior right hemisphere.

• We examined the discharge properties of neurons of the anterior thalamus during states of the hippocampal electroencephalogram (theta and non-theta states).

• An appropriate depth of anesthesia was maintained by continuous monitoring of electrocardiogram and electroencephalogram activity.

• Investigations included a normal electroencephalogram and a normal cranial computed tomography scan.

• The electroencephalogram was very poor, and a cerebral computerized tomographic scan revealed an occipital hematoma.

• Dual electroencephalogram markers of human sleep homeostasis: correlation between theta activity in waking and slow-wave activity in sleep.

• She had a history of multiple absence seizures along with tonic clonic seizures, with her electroencephalogram showing occasional sharp waves bilaterally with spike-like activity.

• It involves placing surface electrodes on the scalp and face to measure electrical brain activity electroencephalogram!, eye movement electrooculogram!, and muscle tone electromyogram!.

• After 10 to 20 minutes of ischaemia the electroencephalogram was brie-y depressed, then progressively recovered.

• The level of anesthesia was monitored throughout by recording the electrocardiogram and electroencephalogram.

• Regional differences of the human sleep electroencephalogram in response to selective slow wave sleep deprivation.
