5, 2019 (HealthDay News) -- White matter rarefaction, arteriolosclerosis, and dorsolateral
frontal cortex (DLFC) neurofibrillary tangles (NFTs) are independently associated with dementia among older men who played football and had chronic traumatic encephalopathy (CTE), according to a study published online Aug.
MRI imaging focused on the whole brain and on the bilateral insula, dorsolateral
prefrontal cortex, anterior cingulate cortex, and superior frontal gyrus.
Figure 2B shows the significant correlations between cortical surface area and visuospatial n-back performance (Time 1): bilateral dorsolateral
prefrontal (r = .63, p = .003 and r = .54, p = .013 for right and left hemisphere, respectively), bilateral superior temporal (r = .57, p = .009 and r = .78, p < .001 for right and left hemisphere, respectively), right anteromedial (r = .50, p = .024), and right posterolateral regions (r = .48, p = .031).
The focus of the fMRI analysis was on brain regions implicated in reward and reward valuation, including the orbitofrontal cortex, dorsolateral
prefrontal cortex, striatum (caudate, nucleus accumbens, putamen), insula, midbrain, and amygdala, as these regions are activated by desire and rewarding experience, such as consuming high-sugar food.
A randomized, double-blind pilot trial with 40 patients with chronic tinnitus compared mediofrontal stimulation using DCC (10 Hz) combined with left temporo-parietal stimulation with figure-of-eight-coil (1 Hz) to the left dorsolateral
prefrontal cortex stimulation with the figure-of-eight-coil (10 Hz) combined with temporo-parietal stimulation with the figure-of-eight-coil (1 Hz).
Moreover, infants' attentional bias to fearful faces and their altruistic behaviour was predicted by brain responses in the dorsolateral
prefrontal cortex measured through functional near-infrared spectroscopy.
La corteza prefrontal dorsolateral
se activa en tareas de planeacion y se relaciona con la memoria de trabajo para recordar las claves visoespaciales (tarea de laberintos), el monitoreo y la comparacion de la informacion visual, la organizacion y la planeacion secuencial (prueba de cubos: Torre de Hanoi, resta y suma consecutiva), la iniciativa, la flexibilidad cognitiva y la categorizacion semantica (clasificacion de cartas, seleccion de refranes) (Diaz & Navarro-Calvillo, 2014; Flores-Lazaro, Ostrosky-Solis et al., 2014).
Normally the ureters enter the bladder on its dorsolateral
surface, within the region of trigone, whereas the ectopic ureters open in the bladder neck, urethra, vagina or uterus (Mayhew et al., 2006; McLoughlin and Chew, 2000).
A variety of procedures have been described for stabilizing vertebral luxations and fractures in the cervical and thoracolumbar regions including dorsolateral
vertebral body plating, external skeletal fixation, and a composite of polymethylmethacrylate (PMMA) with either pins or screws [1, 3-13].
While playing 3D-platform video games has previously been shown to promote grey matter in the hippocampus in younger adults, in the current study, the researchers tested the impact of 3D-platform video game playing, like Super Mario 64, on grey matter in the hippocampus, cerebellum, and the dorsolateral
prefrontal cortex (DLPFC) of older adults.
The study observed the effects of playing the game on three regions of the brain: Hippocampus, Dorsolateral
prefontal cortex and Cerebellum.
