It is also notable
for its pattern of brain activity, which resembles that of the waking brain.
Not exact matches
It showed enhanced
activity in sections
of the
brain responsible
for willfulness and memory — much different
patterns than when people were merely fantasizing about a desired future.
The important point
for Schwartz here is not simply that modified thoughts and behaviors permanently altered
patterns of brain activity, but that such modifications resulted from, as he calls it, «mindful attention» — conscious and purposive thoughts or actions in which the agent adopts the stance
of a detached observer.
For conceptual acts like Schwartz's «mindful attention» to permanently alter
patterns of brain activity that otherwise would remain stuck is therefore exactly what one would expect if the mind transcends the
brain and yet is capable
of physical effects.
Only the series
of dominant occasions known as the soul is a separate society, i.e., a set
of personally ordered occasions which provide continuity in time
for the
patterns already generated in large part by nexus
of living occasions within the field
of activity proper to the
brain.
For example, the intensities and
patterns of the
brain waves in different areas
of the cortex change according to the kind
of mental
activity that is going on.
For instance, suppose that experiment after experiment showed that
brain wave
patterns deviate most from
patterns of neural
activity when people are making what look like free choices.
People at risk
for Alzheimer's disease who do more moderate - intensity physical
activity, but not light - intensity physical
activity, are more likely to have healthy
patterns of glucose metabolism in their
brain, according to a new UW - Madison study.
Yeshurun concludes that the
brain reserves a special
pattern of activity for memories that represent the first time we have associated a smell with a particular thing — and that such pairings are most likely to be laid down in childhood.
When a small subset dies, the
pattern of activity that the olfactory processing regions in the
brain receives
for a specific smell doesn't change very much.
Some research,
for example, shows that
patterns of brain activity can predict our choices or actions before we become consciously aware
of having made a decision, and it may be hard to reconcile this evidence with the notion
of free will.
A new study published in PLOS Computational Biology investigates how temporal acoustic
patterns can be represented by neural
activity within auditory cortex, a major hub within the
brain for the perception
of sound.
When the researchers analysed the
activity in an area
of the
brain that is important
for the production
of song — an area known as nucleus RA — they found a clear correlation between its
activity pattern and the occurrence
of the «stack» call.
Beyond mapping the precise locations
of the
brain areas controlling these movements
for the first time, Chang and colleagues also recorded and analyzed
patterns of neuron
activity in those areas.
Before making decisions about which way to turn,
for example, rats pause to retrace their steps by reactivating
patterns of brain activity established in previous explorations.
Brain Signal
For Awareness: Minimally conscious and vegetative patients show different
patterns of neural
activity.
Jerzy Szaflarski, M.D., Ph.D., professor in the Department
of Neurology and director
of the UAB Epilepsy Center, says the RNS system can be customized
for each individual patient so that it learns which
patterns of brain activity lead to seizures in that patient.
«In pursuit
of pleasure,
brain learns to hit the repeat button: New study in mice shows how the
brain learns to reproduce
patterns of brain activity that lead to reward; provides insights
for treating addiction and obsessive - compulsive disorder.»
«At the heart
of these methods is the ability to test if
patterns of brain activity are more alike
for two similar styles
of music compared to different styles.
Children with the lowest scores on the social cognition tests showed atypical responses to the unknown words — no response at all,
for example, or
activity in a different part
of the
brain, while those with the higher scores showed a more typical
pattern of brain activation in the left hemisphere, the authors report online today in PLOS ONE.
Epilepsy researchers around the world have been working
for decades to identify
patterns of electrical
activity in the
brain that signal an oncoming seizure, but with limited success.
When we move our eyes in REM sleep, according to the study, specific
brain regions show sudden surges
of activity that resemble the
pattern that occurs when we are introduced to a new image — suggesting that eye movements during REM sleep are responsible
for resetting our dream «snapshots.»
For the last decade, neuroscientists have been using the non-invasive
brain - mapping technique functional called magnetic resonance imaging or fMRI to examine
activity patterns in human and animal
brains in the resting state in order to figure out how different parts
of the
brain are connected and to identify the changes that occur in neurological and psychiatric diseases.
They give animals a specific stimulus — a
pattern of stripes, say, or a specific chemical odor — and simultaneously measure the
brain's «code»
for that stimulus: i.e., how neural
activity depends upon the stimulus.
The findings may even have implications
for studying glioblastoma, a common
brain cancer whose ability to grow, migrate and hack into the
brain's blood supply appears to rely on a
pattern of gene
activity similar to that now identified in these neural stem cells.
The
brain's inhibitory systems are essential
for controlling the
pattern of activity in the cortex, which has important implications
for the mechanisms
of cortical operation, according to a Yale School
of Medicine study in Neuron.
(23) Engaging in moderate - intensity physical
activity promotes healthier
patterns of glucose metabolism in the
brain and represents a useful strategy
for preventing glycotoxic Alzheimer's disease.
We already know that there are different kinds
of brain waves
for different
activities, and that the
pattern looks different if you're sleeping versus really concentrating.
