اسلاید 1: AwArness

اسلاید 2: Neurons (nerve cells) in the brain and brainstem produce a variety of nerve-signalling chemicals called neurotransmitters in different parts of the brain. These neurotransmitters in turn act on different groups of neurons in various parts of the brain, which control whether we are asleep or awake. the timing of the activation of these various different processes results from the interaction between the increasing homeostatic drive to sleep and the changing influence of our internal circadian clock.

اسلاید 3: In general, when the alerting areas of the brain are most active, they send arousalsignals to the cerebral cortex (the outer layer of the brain that is responsible for learning, thinking, and organizing information), while at the same time inhibiting activity in other areas of the brain that are responsible for promoting sleep, resulting in a period of stable wakefulness. When the sleep-promoting areas of the brain are most active, on the other hand, they inhibit activity in areas of the brain responsible for promoting wakefulness, resulting in a period of stable sleep.

اسلاید 4: It used to be thought that the brain had a specific “sleep centre” (in the hypothalamus) and a separate “wakefulness centre” (in the reticular activating system in the brainstem), but more recent research has indicated that the situation is actually substantially more complicated than that: wakefulnessactually appears to be regulated by a whole network of redundant structures in the brainstem, hypothalamus and basal forebrain, and is not centred in any one part of the brain.
