Sentences with phrase «gyrus increases»

Overstreet - Wadiche and UAB colleagues posed a basic question: Since the number of neurons in the dentate gyrus increases by neurogenesis while the number of neurons in the cortex remains the same, does the brain create additional synapses from the cortical neurons to the new granule cells, or do some cortical neurons transfer their connections from mature granule cells to the new granule cells?

Now a research team, led by Dr Diego Gomez - Nicola from the Centre for Biological Sciences at the University of Southampton, has detected increased neurogenesis in the dentate gyrus that partially counteracts neuronal loss.

Side view of the brain summarizing blood flow results from tens of thousands of study subjects shows increased blood flow in women compared to men, highlighted in the red colored areas of the brain: the cingulate gyrus and precuneus.

This novel approach — combining information obtained simultaneously from MRI images of the stomach, feelings reported by the subjects, and brain scans — can offer new insights which would otherwise have been unknown, for example that activation in a brain area called the mid-temporal gyrus seems is in some way influenced by the increased water load in this experiment.

In the image, yellow shows the increased RbAp48 in the dentate gyrus.

They found increased functional connectivity between striatal subregions and heteromodal association and limbic cortices including insula and superior temporal gyrus (Di Martino et al., 2011).

The folds in the human brain form sulci (grooves) and gyri (ridges), adding to its surface area to maximize the number of cells that can pack into our skulls, and increasing the quantity of information we can process.

Exercise did not increase progranulin protein levels in frontal cortex (B), thalamus (C), or hippocampus (D), despite producing the expected increase in the number of doublecortin - positive neurons in the dentate gyrus (E, ** p < 0.01).

There was no significant increase in progranulin protein levels in the frontal cortex (Fig. 4B h), thalamus (Fig. 4C i), or hippocampus (Fig. 4D j), despite observing the expected increase in doublecortin - positive neurons in the dentate gyrus (Fig. 4E t), indicating increased neurogenesis as a positive control.

Specifically, FC decreases were identified in regions implicated in episodic memory (EM) processing (posteromedial cortex, ventral medial prefrontal cortex, and angular gyrus), whereas connectivity increases were detected in dorsal and anterior medial prefrontal and lateral temporal cortices.

Compared to sham, verum acupuncture increased the connectivity between the amygdala, the PAG (periaqueductal gray) and the insula, and decreased the connectivity between the amygdala with the middle frontal cortex, the postcentral gyrus and the posterior cingulate cortex (PCC).

When contrasting sequences with two levels of embedding against one, we observed decreased behavioural performance and increased BOLD responses in the inferior parietal lobule (IPL) and the middle frontal gyrus (MFG) of the dorsolateral prefrontal cortex (dlPFC).

By independently manipulating the grammaticality and auditory tonal working memory demands of nested atonal musical sequences, we found that grammatical violations of nested musical dependencies led to increased BOLD responses in the right inferior frontal gyrus (IFG) and bilateral anterior insular cortices (AIC), whilst increased auditory working memory demands led to enhanced responses in the bilateral middle frontal gyri (MFG) and inferior parietal lobules (IPL).

For the main effect of GRAMMATICALITY (UNGRAMMATICAL > GRAMMATICAL), we found a cluster of increased BOLD response with maxima in the right inferior frontal gyrus (IFG; pars opercularis, triangularis, and orbitalis), right middle frontal gyrus (in the dorsolateral prefrontal cortex), and right anterior insular cortex (AIC).
