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.
This was perceived as the activation-synthesis model, stating that brain activation during REM sleep results in synthesis of dream creation. [1] Hobson's five cardinal characteristics include: intense emotions, illogical content, apparent sensory impressions, uncritical acceptance of dream events, and difficulty in being remembered. [6]
Some studies have shown that dreaming is triggered by engagement of the Mesocortical-Mesolimbic Dopamine system in the Ventromesial quadrant of the frontal lobes, [7] which, according to findings in affective neuroscience, plays a key role in activating motivated behaviour, curiosity and expectations of the external world, that is, the ...
The major sulci and gyri mark the divisions of the cerebrum into the lobes of the brain. The four major lobes are the frontal, parietal, occipital and temporal lobes. Other lobes are the limbic lobe, and the insular cortex often referred to as the insular lobe. There are between 14 and 16 billion neurons in the human cerebral cortex. [2]
Studies have found the frontal lobes to be involved in the executive functions of the brain, which are higher level cognitive processes. [28] This control process is involved in the coordination, planning and organizing of actions towards an individual's goals. It contributes to such things as one's behaviour, language and reasoning.
The parietal lobe is positioned above the occipital lobe and behind the frontal lobe and central sulcus.. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the ...
BvFTD, which results from damage to the frontal lobes of the brain, mainly causes problems with behaviour and personality. PPA, when damage occurs to the temporal lobes on either side of the head ...
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral ...
