As emotions heighten, the prefrontal lobe is essential to controlling them, and serotonin is a necessary mechanism for this process to work effectively.
In particular, frontal lobe and prefrontal lobe dysfunction have been suggested (Hynd et al., 1991).
Studies from other countries have revealed abnormal GABA concentration in the medial prefrontal lobe (cingulate gyrus or ventromedial prefrontal cortex) in schizophrenia.
Schizophrenia patients and their unaffected relatives have smaller volumes of prefrontal lobe gray matter, a new report suggests.
To answer to the question posed in the paper title, that is, if there is a causal relationship between prospective memory impairment and executive dysfunction in prefrontal lobe damaged patients, the result of the present investigation (together with other neuropsychological evidence of the literature) suggests a quite problematic response.
The majority of researchers that conduct neuropsychological studies of transgressors have primarily concentrated on the anterior regions of the brain, more specifically, areas of the prefrontal lobe. These areas are directly involved in the highest mental functions such as selective attention, working memory, action-planning competency, forethought, self-control and, at the most basic level, the regulation of the affective-emotional life.
The first Buddhist studied showed more left prefrontal lobe activity than anyone Davidson had measured before.
Neural deficits are attributable to disease processes that affect the olfactory bulb, olfactory tract, or the central olfactory pathway, including the prefrontal lobe, septal nuclei, amygdala, and temporal lobe.
[39] In first-episode schizophrenia reductions of the gray matter in the anterior cingulate gyrus and in the right parietal lobe were reported by 15 to 25% of studies and reductions of the gray matter in the inferior frontal lobe and the medial prefrontal lobe were also reported.
In particular, CFT disturbances have been documented in patients with focal prefrontal lobe damage, especially of the orbitofrontal region and in some neurological and psychiatric populations related to frontostriatal circuit dysfunctions, such as Parkinson's disease [25], Huntington's disease [26], and schizophrenia, in which alterations of the frontal lobe have been observed [27, 28].
Functional imaging studies found that the insula, especially the front insula, prefrontal lobe, and other parts of the limbic system participate in the regulation of emotions (e.g., guilt and sadness).
