چکیده
BACKGROUND: Studies have emphasized on the frontal EEG asymmetry as a mediator of emotional states. This research was aimed to examine the overall and asymmetric activities of the brain lobes under the affective states. METHODS: A coupling EEG was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states. RESULTS: Bilaterally decreased activities in anterior and posterior regions and also a superimposed right asymmetry in posterior regions were revealed. CONCLUSIONS: Variability of frontal, temporal and parietal lobes together with a superimposed relative right posterior activity may mediate affective states.

متن کاملP 95: Result of Alcohol Excessive Drinking in the Brain and Varying Mental Health Side Effects
Alcohol directly affects astroglial cell function, including inflammation-related activity. And it also affects microglial cell development and function in specific ways that interfere with microglial interactions with the immune system and with neurons. Neuroinflammatory processes might be involved in alcohol-induced brain damage. Alcohol use, misuse and getting used to it causes differe...
متن کاملChanges in Catecholamines and Acetylcholinesterase Levels of Crebellum, Mid-brain and Brain Cortex in Chromium Treated Rats
The short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. Rats were injected daily with varying amounts of chromium. The short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. Acetylcholinesterase activity was also re...
