<p>Any "theta band" activity may be slowed thalamo-cortical alpha or limbically generated rhythmic slow activity (theta), as stated in Steriade's 1990 IFCN position paper on EEG rhythm generators.&nbsp;&nbsp;</p><p><span style="font-size: 1rem;">The limbic projections are spatially limited cortically at the frontal/central midline via the cingulate as well as the temporal locations seen from the parahippocampal cortex. The parahippocampal cortex reflects the temporal lobe's monopoles of the hippocampus and Amygdala. Monopoles are not seen exteriorly directly, but we often see a reflection in adjacent areas even without the direct measurement.... this s the case with the cingulate theta which reflects nucleus accumbens activity seen in "FMT" frontal midline theta seen in brief bursts on memory retrieval tasks as the NA provides ACH to the temporal lobe's limbic structures via the diagonal band of Brocca connected to the amygdala/hippocampus complex allowing rhythmicity.</span><br></p><p><b>Precuneus</b></p><p>The precuneus&nbsp; is suggested to be the 'core node' or 'hub' of the default mode network, a web of connections that are activated during "resting consciousness" in which people do not engage intentionally in sensory or motor activity. This involvement in the default network is suggested to underlie its role in self consciousness.&nbsp; It is one of the areas of the brain most deactivated during slow-wave sleep and rapid eye movement sleep and&nbsp; is involved in memory tasks, including episodic memory, source memory, and contextual associations. Lastly, it is also, together with the dorsal premotor cortex, involved in visuospatial mental operations.&nbsp; While the premotor area engages in the mental operation, the precuneus aids monitoring the success of that operation in terms of internally represented visual images.</p><p><b>Amygdala</b></p><p>The small almond shaped amygdala lies deep in the temporal lobe and is involved primarily in rage, shame, and fear reactions, but also more generally in establishing the emotional valance of incoming stimuli. The RH amygdala is devoted to survival and reacts to threats, both real and perceived (63). This area of the brain is prone to kindling, which is essentially repetitive Neuronal firing that gives rise to high amplitudes, until the pattern collapses. Each kindling lowers the threshold of the future ones, making them more likely.</p><p><b>Cuneus &amp; PCC</b></p><p>The areas, subcortically, which appear to be the origin of the excessive delta and theta are the cuneus and the posterior cingulate cortex. Both of these areas are implicated in the use of the default mode network, one of the basic resting state networks of the brain.&nbsp; Observations of the default mode network (DMN) during sleep show, just as during the DMN activity in mind wandering, that portions of the pre-frontal cortex are active during dreaming, as are the medial temporal lobe structures and the posterior cingulate (all of these points are nodes that make up the network of the DMN). Conversely, other studies show that, in REM sleep, executive-processing regions of the pre-frontal cortex are mostly deactivated, beyond levels seen during waking mind wandering, which suggests that dreaming may be an “intensified” version of waking mind wandering (Fox, Nijeboer, Solomonova, Domhoff, &amp; Christoff., 2015). Rizzolatti, Semi, &amp; Fabbri-Destro (2013) contend that the activation of the DMN might correspond to the psychoanalytic unconscious (p. 5).</p><p>This area is responsible for the evaluation of stimuli. It is also implicated in the recall of episodic memory and has a role in pain perception. It is important in attention comprehension and visual processing. (Choo et al., 2012; Choo et al., 2009). It also plays a key role in the integration and synthesis of almost all sensory input.&nbsp; This area is also implicated in the distinction of self from other (Thompson &amp; Thompson, 2015). There is the possibility that one may feel anterograde amnesia when it is damaged. This area, lastly, is involved in the identification of pain and has connections to the hippocampus, the posterior parietal cortex, the posterior parahippocampal gyrus, and the dorsal striatum (all implicated in memory) (Thompson &amp; Thompson, 2015).</p><p><b>VMPFC</b></p><p>The F7 site (left hand side) is located above the ventromedial prefrontal cortex, but also affects the dorsolateral prefrontal cortex and the executive system. This includes auditory working memory, selective attention, word retrieval, and functions related to Broca’s area, including word generation. Mood regulation dealing with emotional-contextual information also has to do with this area, as well as verbal fluency, lexical functions, phonemes, grammar and syntax. This area is also involved in episodic, declarative, and working memory. This area covers Brodmann areas 44, 45 and 46. On the right hand side, in adults (F8), this involves spatial and visual working memory, sustained attention, prosody, sensing the gestalt, and the conscious processing of facial recognition and emotions (Thompson &amp; Thompson, 2015, p. 53).&nbsp; These bilateral areas (F7 and F8) have links to the medial prefrontal cortex, the insula, and the anterior cingulate, which are involved in the cortisol secretion related to stress (Levine et al, 1998).</p>
