Serial digit learning test (SDLT) is traditionally related to mesial temporal lobes. As sequencing is closely related to the frontal lobes, SDLT is also thought to activate these areas. In this paper, methodology used in the functional magnetic resonance imaging (fMRI) of the hypothesised frontal activations is presented. By the use of a specially designed variant task we were able to detect su...

The virtual endocast of MH1 (Australopithecus sediba), obtained from high-quality synchrotron scanning, reveals generally australopith-like convolutional patterns on the frontal lobes but also some foreshadowing of features of the human frontal lobes, such as posterior repositioning of the olfactory bulbs. Principal component analysis of orbitofrontal dimensions on australopith endocasts (MH1, ...

BACKGROUND: Studies have emphasized on the frontal EEG asymmetry as a mediator of emotional states. This research was aimed to examine the overall and asymmetric activities of the brain lobes under the affective states. METHODS: A coupling EEG was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states. RESULTS: Bilaterally decre...

The function of the frontal lobes and the related frontal lobe syndrome have not been described in detail until relatively late in history. Slowly, the combination of knowledge from animal models, the detailed examination of symptoms after traumatic frontal lobe injuries, and the rise and fall of psychosurgery has led to increasing insight into frontal lobe function. The frontosubcortical circu...

The patient had pneumocephalus due to a bony defect at the level of his scalp tumour. As shown in fig 1, the frontal lobes are compressed and the interhemispheric space between the two tips of the frontal lobes gives rise to the “Mount Fuji” sign, named after its resemblance to the silhouette of the Japanese volcano. A CT of the vertex on a bone window (fig 2) shows the scalp defect, with exten...

Patients with limited focal frontal and nonfrontal lesions were tested for visual perspective taking and detecting deception. Frontal lobe lesions impaired the ability to infer mental states in others, with dissociation of performance within the frontal lobes. Lesions throughout the frontal lobe, with some suggestion of a more important role for the right frontal lobe, were associated with impa...

The evolutionary success of Homo sapiens is attributed to the following two factors: the upright body posture (which freed our hands and allowed unconstrained operation of various objects) and intensive development of the frontal lobes, mainly the Broca area of the brain. Underlining the uniqueness of the human brain, we often forget about the fact that the frontal lobes - the most developed pa...
