| Abstract | ||||
| THE ARCHITECTURAL shapes of environment may affect the activity of living inhabitants. Accordingly the present work was aimed to study and clarify the influences of architectural shapes of environment on the electrical activity of rat's brain. The brain activities (electroencephalogram, EEG) recorded from rats housed into 2 different models, pyramidal and inverted pyramidal shapes for 3 weeks were studied. The obtained results showed a drop in the mean power amplitude of almost all frequency bands of rat's brain activities placed in pyramidal shape especially of θ , α and β bands. This effect was more pronounced in motor than in visual cortex. On the other hand the recorded rat's brain activities housed in an inverted pyramidal shape showed an enhancement in the mean power amplitude of all frequency bands. The obtained results proved that rats kept in pyramidal shape were more relaxed and more active than that inside an inverted pyramidal environment. | ||||
