Two main frontal areas have been implicated in the dream process. The first involves the deep white matter of the frontal lobes (just above the eyes). The main systems at work here involve the mesolimbic and mesocortical dopaminergic pathways. There are connecting fibres that run between frontal and limbic structures.
Memory goals can either be deliberate (top-down) or in response to an external memory cue (bottom-up). The superior parietal lobe sustains top-down goals, those provided by explicit directions. The inferior parietal lobe can cause the superior parietal lobe to redirect attention to bottom-up driven memory in the presence of an environmental cue.
The parietal lobe is located directly behind the central sulcus, superior to the occipital lobe and posterior to the frontal lobe, visually at the top of the back of the head. [18] The make up of the parietal lobe is defined by four anatomical boundaries in the brain, providing a division of all the four lobes.
Mythological themes are rich in such images, which dreams use. These images, through the medium of the symbol, allow us to go beyond consciousness and inform the subject of an underlying problem or future evolution of the unconscious personality. If the dream's content is too shocking for the conscious mind, the latter immediately awakens in ...
Unlike the waking state, the brain cannot recognize its own condition; that it is in the midst of the dream and is not the same as the real world. [1] The brain has a single-minded state of primary consciousness during dreaming, which allows the brain to reach greater perception and awareness of a single scenario out of images and dreams. [ 1 ]
Each dream example is divided into a minimum of three aspects: the condition whereby the context is outlined in which the dream occurred. the scene, consisting of a detailed description of the actual plot and images that the dream consisted of and; the interpretation. Hereby Silberer provides the reader with an explanation of the dream based on ...
The lobes are classified based on their overlying neurocranial bones. [4] A smaller lobe is the insular lobe, a part of the cerebral cortex folded deep within the lateral sulcus that separates the temporal lobe from the parietal and frontal lobes, is located within each hemisphere of the mammalian brain.
The superior longitudinal fasciculus (SLF) is an association tract in the brain that is composed of three separate components. [1] [2] It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes. [2]
