130Why do you think about that EEG can reflect the state of wakefulness and sleep.

131. How do you classify EEG waveforms?

132. Briefly describe the features of α, β, θ and δ forms in EEG.

133. What is the neural mechanism underlying the formation of α wave?

134. What are brain structures responsible for maintaining wakening?

135. What is the location of ascending reticular activating system in the brain (ARAS)? 

136. Why is sleep considered as an active inhibitory process?

137. Light stimulation of the retina changes the activity of the suprachiasmatic nucleus and then the paraventricular nucleus, which subsequently inhibits melatonin production in the pineal gland by reducing sympathetic input via superior cervical ganglion, thereby inhibiting sleep. What happens to the production of melatonin when light is off, and why?

138. What is the circadian rhythm for body temperature and the release of growth hormone and cortisol in a 24 hour cycle?

138. What is the difference between Rapid eye movement (REM) and Sleep Non-rapid eye movement (NREM)?

139. What is the contribution of acetylcholine, serotonin and norepinephrine to the wakefulness and different types of sleep?

140. What is learning?

141. What is the difference between associative learning and non-associative learning?

142. What is memory?

143. What are the neurochemical mechanisms underlying different types of memory?

145. What is the difference between anterograde amnesia and retrograde amnesia?

146. Briefly describe the association between cerebral areas and language functions of the dominant hemisphere.

147. What is the difference in the aphasia between damage of Bocas area and Wernickes area of the dominant hemisphere?
