Two patients had alexias after left occipital lobectomies. Case 1 was a 55-year-old man with a glioblastoma. At 4 months after surgery he could read slowly, but reading was neither efficient nor pleasant. Case 2 was a 19-year-old male who had a more restricted, medial occipital ...
Thehippocampus, within the medial temporal lobe (MTL), was once thought to be the exclusive locus of several memory functions, but is now understood to be one component of systems that subserve these behaviors. It is important in the initial consolidation and stabilization of early long-term me...
Briefly, the lateral frontal convexity, including Broca's area, may have evolved from the supplementary motor areas and medial frontal lobe which in turn evolved from and is richly interconnected with the anterior cingulate (e.g. Sanides 1964). The amygdala (and hippocampus) gave rise to the ...
Much attention has been devoted to characterizingAPOE-ε4-related changes in medial temporal lobe regions, notably in the hippocampus and parahippocampal regions24,25,26due to their importance for episodic memory. Hippocampal volume loss on magnetic resonance imaging (MRI) is also one of the diagnost...
measures that we analysed in the present study, with an overall similar regional pattern. Higher heritabilities were found particularly for regions that are important in the language system (for example, superior temporal cortex) and limbic system (for example, medial temporal and cingulate cortex)....
language functions. Interestingly, a study that used verbal fluency tests as a measure of language abilities also reported on involvement of the VL alongside the central medial and ventral medial nuclei33, while another study that used retrospective chart review to evaluate language, reported ...
Can you die from temporal lobe epilepsy? What kinds of clinical symptoms are often associated with damage to the frontal, parietal, temporal, and occipital lobes of the brain? What does the temporal lobe control? What does the anterior temporal lobe control? What is a bilateral medial tempor...
Each of the two eyes can share the undisturbed tectum by terminating in mutually exclusive, eye-specific stripes that alternate across the medial-lateral extent of the tectal lobe. Invading axons from the ipsilateral eye must actively displace established synapses from the contralateral eye in order ...
Grasping using two forelimbs in opposition to one another is evolutionary older than the hand with an opposable thumb (Whishaw and Coles in Behav Brain Res
As it ascends, the main portal vein produces several minor branches to the hilum above the origin of the left gastric vein, including a medial branch to the left portion of the caudate lobe and a lateral branch to the right caudate lobe. As described earlier, the left portal vein remains ...
