Physiology - Electroencephalography (EEG) (B7) Questions With Solutions A flat EEG (no electrical activity) is clinical evidence of death Patterns of rhythmic neuronal electrical activity recorded are called brain waves (brain rhythms) scalp EEG a pair of electrodes are attached to scalp connected to a differential amplifier •Amplifier will reveal a pattern of voltage fluctuations over time •Amplitude between -100 µV and +100 µV •Frequency 0-100 Hz

Electroencephalography (EEG) Questions and Answers 100% Accurate What is an EEG (electroencephalograph)? Electroencephalography (EEG) is a method of detecting neural activity by placing electrodes on the scalp. EEG recorded at the scalp is non-invasive - however, it is also possible to record intra-cranial EEG by measuring activity directly at the exposed cortex. EEG is cheap and (relatively) easy to conduct. The temporal resolution of an EEG is great, but the spatial resolution is poor. ...

Electroencephalography Lab Questions With Solutions How does greater cortical activation affect alpha activity? lowers it When are beta waves seen? awake, alert, eyes open. When are theta waves seen? not in adults, more in children. Normal during sleep at all ages When are gamma waves seen? higher mental activity

Lab 4 Electroencephalography Questions With Solutions Beta waves are of lower amplitude, but they have the fastest frequency of all the brain waves Visual stimuli and mental activity evoke them seen in rapid-eye-movement (REM) sleep sleep paralysis . During REM sleep, signals from the brainstem shut down both sensory afferents and motor efferents (BETA) The aminergic (inhibitory) neurons in the brain switch off, leaving the cholinergic (excitatory) neurons free to fire in response t...
