Humans have at least three face processing regions in the brain, including the fusiform face area, or FFA, which is associated with distinguishing faces from other objects. (technologynetworks.com)

I will go out on a limb and say that I think similar changes also occur in human brains after hearing loss, specifically in Broca's area, a part of the human brain that plays an important role in generating speech and that also receives inputs from the auditory system," Mooney said. (scitechdaily.com)
Since its discovery in the 1860's, Broca's area has been assumed to be the region of the brain responsible for human speech with responsibilities ranging from language comprehension to actually speaking words. (iflscience.com)
Broca's area. (iflscience.com)
While Broca's area was quite active when the test subjects were reading the words and determining what to say in their heads, as was expected, the moment they began talking, the area curiously became inactive. (iflscience.com)
It has traditionally been believed that language processing and speech production largely came from Broca's area (as well as Wernicke's area), which would have remained active during the actual act of speaking. (iflscience.com)
This new finding helps us move towards a less dichotomous view where Broca's area is not a center for speech production, but rather a critical area for integrating and coordinating information across other brain regions. (iflscience.com)
The function of Broca's area was first identified when Pierre Paul Broca noticed that those who had suffered strokes or had other brain injuries affecting this particular region of the frontal lobe also had difficulty speaking. (iflscience.com)
Broca's area shuts down during the actual delivery of speech, but it may remain active during conversation as part of planning future words and full sentences," Flinker explained. (iflscience.com)
There is still much to learn about the function of this area, as there have been instances of damage to Broca's area that did not result in impaired speech. (iflscience.com)

The function of these rapidly changing influences is not yet known, but the authors hypothesize that they may allow cortical areas to control different aspects of processing in the downstream brain regions they influence over very short time spans. (neurosciencenews.com)
Processing of sensory information depends on the interactions between hierarchically connected neocortical regions, but it remains unclear how the activity in one area causally influences the activity dynamics in another and how rapidly such interactions change with time. (neurosciencenews.com)
Barbey said these shrapnel-induced injuries typically produced focal brain damage, unlike injuries caused by stroke or other neurological disorders that affect multiple regions. (neurosciencenews.com)
This allowed them to compare the discourse comprehension abilities of patients with damage to a particular voxel or cluster of voxels with those of patients without injuries to those brain regions. (neurosciencenews.com)
Rather than engaging brain regions that are classically involved in language processing, our results indicate that discourse comprehension depends on an executive control network that helps integrate incoming language with prior knowledge and experience," Barbey said. (neurosciencenews.com)
The findings help us understand the neural foundations of discourse comprehension, and suggest that core elements of discourse processing emerge from a network of brain regions that support language processing and executive functions. (neurosciencenews.com)
Now that we know which brain regions are involved, we may be able to use this knowledge to alter someone's capacity to be hypnotized or the effectiveness of hypnosis for problems like pain control," said the study's senior author, David Spiegel , MD, professor and associate chair of psychiatry and behavioral sciences. (stanford.edu)

A more sort of modern conception is thinking of depression as a circuit dysfunction, meaning that there's something about the way cells in the brain are talking to each other that is not quite right," says Dr. Vikram Rao, an author of the new study and an assistant professor of clinical neurology at UCSF. (kpbs.org)

If, on the other hand, social skills are required, the posterior parts of the IPL in both hemispheres of the brain spring into action simultaneously. (mpg.de)
However, most functions (such as memory) require coordination of several areas in both hemispheres. (msdmanuals.com)

Therefore, the IPLs on both sides of the brain probably work together here. (mpg.de)

Harmless at the low intensities routinely used for imaging bodily tissues, high-intensity focused ultrasound is approved for the ablation, or deliberate destruction, of certain tissues, including portions of a central brain structure called the thalamus to treat the condition known as essential tremor. (stanford.edu)
The ultrasound in these experiments was delivered in a series of short staccato pulses separated by periods of rest, giving the targeted brain tissue plenty of time to cool off between pulses. (stanford.edu)
abstract = "Focused ultrasound combined with intravenously injected microbubbles (FUS) is known to non-invasively, locally, and transiently increase the permeability of the blood-brain barrier (BBB). (au.dk)

Ilya Monosov, PhD, shows data on brain activity obtained from monkeys as they grapple with uncertainty. (labmanager.com)
Activity in those areas drove the monkeys' motivation to find information about good things that may happen. (labmanager.com)
Surprisingly, they found that the effect of manipulating one area on the activity in another varied over time on a fast timescale. (neurosciencenews.com)
For example, a neuron in area V1 could decrease its activity in response to area LM at one time point but not be influenced by LM activity 100 milliseconds later. (neurosciencenews.com)
However, a new paper published in the Proceedings of the National Academy of Sciences explains that activity in this area is rather low when an individual is speaking, which goes against conventional wisdom about the function of this region. (iflscience.com)
They were asked to read words aloud from a piece of paper or repeat what another person had said, and their brain activity was analyzed during this time. (iflscience.com)
Then, they observed the brains of those 57 participants using functional magnetic resonance imaging, which measures brain activity by detecting changes in blood flow. (stanford.edu)
Now we find that indeed, when we temporarily shut the activity down in that part of the brain it really does affect the sensory parts of decisions. (earth.com)
