Instead, consciousness appears as a type of collective agreement
among different brain regions, a dynamic state made possible by an active coalition of parts.
White matter appears white because of the density of axons, the signal - carrying cables allowing communication
between different brain regions responsible for complicated tasks such as language and memory.
While preparing them for brain surgery, Penfield stimulated
different brain regions with electrodes and asked the patients to describe any sensations that resulted.
Working independently, Dulac and Anderson mapped patterns of brain activity in
different brain regions while mice sniffed, ignored, fought, or mated with other mice.
However, despite these similarities, the researchers noted that the relationship between these sleep waves and cognitive performance differs between neurotypical and autistic children,
as different brain regions are involved for each group.
The nucleus accumbens is recognized as an integration centre for signals coming from
many different brain regions, but the precise role of the different connections, and the means of their integration, resulting in specific behaviours, was until recently impossible to dissect.
Currently, fcMRI is not used clinically, and the kinds of MRI and CT scans used to assess stroke damage don't measure how
well different brain regions work together.
For instance, knowing if there is a simple increase or decrease in connectivity between brain regions compared to healthy individuals, or whether those with autism use
entirely different brain regions to implement cognitive flexibility will enable researchers to better design interventions to improve cognitive flexibility skills.
«
When different brain regions assume the highest importance within a functional brain network is the key to improving both prediction and control of epileptic seizures,» Lehnertz said.
«In our studies, we are showing that the extracellular matrix network is an important part of
distinguishing different brain regions and that, subsequently, physiological and pathophysiological processes in these brain regions are unique.
«This shows how important it is to
implement different brain regions into in vitro models, especially when studying how neurological diseases impact connected regions of the brain.»
At the cellular level, although they share canonical types of inhibitory interneurons (INs) and excitatory principal neurons (PNs), it remains largely unknown to what extent a single type in
different brain regions displays similarity in gene expression, axonal shape, connectivity, and developmental origins.
Mathematicians from the University of Twente, together with researchers from the University Medical Center Utrecht, have shown that it is sensible to examine the interconnections between
different brain regions closely, instead of searching for abnormal regions only.
To trace the longer pathways that
interconnect different brain regions, CBS labs developed a genetic method to label each individual nerve cell a different color to identify and track axons and dendrites over long distances.
Brain recording technology such as the new Neuropixels probe will allow us to make an unprecedented «neural activity map» highlighting how
different brain regions behave during the task.
After spheroids representing two
different brain regions fuse in a dish, neurons from one spheroid (green) migrate into the second and forge connections with neurons residing there.
Wilder Penfield was the first neurosurgeon to explore the neural locus of epilepsy at the same time as mapping behavioral / memory functions of
different brain regions through electrical stimulation in fully conscious patients.
Taylor et al. used microarray analysis to define molecularly distinct subsets of human ependymomas that arise in different brain regions [8].
Although Dulac's and Anderson's teams
examined different brain regions, both researchers observed a similar relationship between sex - specific neural activity and social behavior.
Researchers used diffusion tensor imaging (DTI), an enhancement of magnetic resonance imaging (MRI), to evaluate and compare the structural and functional properties of the main connections
between different brain regions.
WHITE MAGIC Targeting parts of the brain's white matter, the tissue that
connects different brain regions (shown), may be key to whether stimulating the brain with electricity will work as a treatment for memory problems and other ills.
By looking at activation of
different brain regions while test subjects were exposed to different listening conditions, Dr. Johnsrude's research has revealed that the early processing of sound, which occurs in a brain region called the primary auditory cortex, depends on higher - level linguistic knowledge encoded in other regions of the brain.
In a virtual arena, at - risk populations keep to the edges and appeared to navigate using different brain regions
Previous studies have shown
for different brain regions that the metabotropic glutamate receptor 5 (mGlu5 receptor) plays a crucial role in this long - term form of synaptic plasticity.
But it's not yet possible to say whether the activation patterns observed by the two groups in
different brain regions are influencing each other, Anderson says.
And customizing the feedback fMRI is generally more difficult than customizing the dose of a drug, because each person might be helped best by targeting
a different brain region with a different mental exercise.
Andersen and his colleagues wanted to improve the versatility of movement that a neuroprosthetic can offer to patients by recording signals from
a different brain region other than the motor cortex, i.e., the posterior parietal cortex (PPC), a high - level cognitive area.
