Different patterns of EEG activity were superimposed on the similar background of EEG activation during and after warm and cold stimulations. | |||||||||||||||
| |||||||||||||||
|
On the other hand, intracerebroventricular administration of cocaine (7.5, 15, or 30 micrograms) induced significant EEG activation without affecting ICP. | |||||||||||||||
| |||||||||||||||
|
It is well-known from animal and human studies that, as a central nervous stimulant, cocaine induces electroencephalographic (EEG) desynchronization. | |||||||||||||||
| |||||||||||||||
|
There was a postnatal increase in EEG power as, before clamping, pups aged 5-7 days exhibited isoelectric traces, whereas those aged 12-14 days and 21-22 days had intermittent EEG activity where the power in all frequencies was significantly lower at the former than at the latter age. | |||||||||||||||
| |||||||||||||||
|
Anesthesia was induced with propofol 2.5 mg/kg, fentanyl 3 micrograms/kg (followed by an infusion of 2 micrograms/kg/h), vecuronium 0.1 mg/kg, and maintained with a propofol infusion (250-300 micrograms/kg/min) sufficient to induce EEG silence. | |||||||||||||||
| |||||||||||||||
|
Although the painful and non-painful muscular stimulations evoked similar EEG topographic patterns, statistics demonstrated that distinct EEG activation over different areas of the head were induced by the painful and non-painful stimulation compared with the baselines. | |||||||||||||||
| |||||||||||||||
|
These results may imply that the painful and non-painful muscular stimulations evoke distinct EEG activation in different neural networks of the human brain and the intensity of nociceptive input from muscle may encode the variety of topographic EEG changes. | |||||||||||||||
| |||||||||||||||
|
(F) Two independent spatial clusters of EEG activation, fronto-temporal delta-theta-beta activities and posterior parietal alpha activities emerged during CPT. | |||||||||||||||
| |||||||||||||||
|
In healthy humans, increase of low frequencies in EEG show a clear correlation with decline of sustained attention, which is necessary in preceding memory efforts [25]. | |||||||||||||||
| |||||||||||||||
|
Our results support earlier findings from intracerebral electrode recordings demonstrating that MST- and ECS- induced seizures elicit differential patterns of EEG activation. | |||||||||||||||
| |||||||||||||||

ATP-Dependent Infra-Slow (<0.1 Hz) Oscillations in Thalamic Networks
An increasing number of EEG and resting state fMRI studies in both humans and animals indicate that spontaneous low frequency fluctuations in cerebral activity at <0.1 Hz (infra-slow oscillations, ISOs) represent a fundamental component of brain functioning, being known to correlate with faster neuronal ensemble oscillations, regulate behavioural performance and influence seizure susceptibility. | |||||||||||||||
| |||||||||||||||
|
24 Hz) spike/poly-spike wave (SW/PSW) complexes intermingled with fast (1020 Hz) runs and which have been likened to the EEG activity that occurs during LGS in humans [24]. | |||||||||||||||
| |||||||||||||||
|
Consistently with this the ISS reflects estimated periods of the mutual temporal stabilization of quasi-stationary segments (spatially remote events) in the multichannel EEG [15]. | |||||||||||||||
| |||||||||||||||
|
-opiate receptor agonists are uniformly sedative in man, dog and rabbit, they often have alerting effects, usually demonstrated as EEG activation, in cats, rats and mice. | |||||||||||||||
| |||||||||||||||
|
Furthermore, these findings provided a sensitive and mechanistic description of how the benzodiazepine class of sedative anxiolytics paradoxically increase EEG beta (1525 Hz) power in moderate to high concentrations (Liley et al. 2003). | |||||||||||||||
| |||||||||||||||
|
Interestingly, as in mammals, the first 2 hours of recovery sleep in sparrows were characterized by large increases in EEG power not only in the low frequency range, but also across most frequencies in the 10 to 20 Hz range. | |||||||||||||||
| |||||||||||||||
|
In sparrows, the increase in EEG power in the spindle frequency range (1216 Hz) is especially intriguing, because spindles were not detected by visual scoring. | |||||||||||||||
| |||||||||||||||
|
It has recently been suggested, however, that prolonged wakefulness results in stronger cortico-cortical connections, which in turn would drive greater neuronal synchronization during sleep, leading to increased EEG power across all frequencies [17]. | |||||||||||||||
| |||||||||||||||
|
High-amplitude, low-frequency EEG activity reached its peak during SWS, when the birds were motionless, with eyes always closed and head either positioned beneath the wing, hanging forward or tucked in tightly toward the body. | |||||||||||||||
| |||||||||||||||
|
In the cat, it has been shown that cortical states characterized by high levels of EEG activation are associated with high amplitude, sustained gamma oscillations (Herculano-Houzel et al. 1999; Siegel and König 2003), suggesting that synchronization of spiking responses may be facilitated by oscillatory activity. | |||||||||||||||
