July 30, feature. Some animals, such as birds, whats the meaning of dominant hemisphere, and whales, can engage in unihemispheric sleep, in which one hemisphere of the brain sleeps while the other hemisphere remains awake. Staying half-awake allows animals to literally "keep an eye open" for predators, and for migrating birds, allows for uninterrupted flight for days or even weeks on end. Although unihemispheric sleep is not known to occur in humans, recent research has found whats the meaning of dominant hemisphere humans exhibit a similar sleeping style when they experience troubled sleep in a new location for the first time, called the "first night effect.

Now in a new study, researchers have further investigated the underlying mechanisms of this sleep activity in order to develop a model of unihemispheric sleep in the human brain. The paper, by Lukas Ramlow et al. In the human brain, the sleep and wake states can be distinguished by their different forms of electrical activity. When awake, neurons in the brain fire in an asynchronous, somewhat chaotic fashion, whereas neurons in the sleeping brain fire in a more synchronized manner.

Previous research has suggested that the two hemispheres of the brain can be viewed as two coupled populations of oscillators, as both hemispheres generate electrical signals in a coordinated way. From this perspective, unihemispheric sleep occurs when the brain occupies a state of two coexisting domains, consisting of one synchronized whats the meaning of dominant hemisphere hemisphere and one incoherent awake hemisphere.

In physics, this type of state, which is characterized by the coexistence of order and disorder, is called a "chimera state. Using MRI data from 20 humans on 90 different brain sites, the researchers investigated how the brain transitions from incoherence awake to synchronization asleep. As they explain, the coupling within each individual hemisphere intra-hemispheric coupling is stronger than that between the two hemispheres inter-hemispheric coupling.

By decreasing the inter-hemispheric coupling strength while keeping the intra-hemispheric coupling strength fixed in their model, the researchers observed that one hemisphere exhibited more synchronized activity than the other, resembling unihemispheric sleep and the chimera state. Moreover, we have identified the mechanism of this relying on different strengths of the intra-hemispheric strong and inter-hemispheric weak coupling.

The results support the idea that unihemispheric sleep requires a certain degree of separation between the two whats the meaning of dominant hemisphere. The researchers found that this separation can occur due to the brain's structural asymmetry. It's well-known, for example, that the two hemispheres have different sizes of corresponding brain regions and different neuronal densities within these regions. Based on their model, the researchers found that even a slight structural asymmetry results in a dynamical asymmetry, in which one hemisphere exhibits more synchronized firing patterns than the other, as in a chimera state.

So overall, the structural asymmetry in the brain may explain the underlying mechanisms of unihemispheric sleep and the related first-night effect, but many questions remain unanswered. Can we identify a kind of relay in the brain which mediates synchronization between different areas of the brain? How is such relay synchronization related to memory, or to learning, or to perception?

Also, we are investigating how epileptic seizures, which are associated with spontaneous strong synchronization of the braincan be initiated and terminated.
