Neurology: Not only "indifferent"-indifference may mean a disease in the brain!
Neurology: Not only "indifferent"-indifference may mean a disease in the brain! 1,
In order to explore whether the interruption of the white matter network in CSVD is the cause of indifference (rather than depression), professors from the Department of Clinical Neuroscience at the University of Cambridge in the United Kingdom used diffusion tensor fiber imaging (DTI) to reconstruct the white matter pathways of patients with CSVD and then Network analysis for analysis
.
Researchers completed measurements of apathy and depression on 331 CSVD patients, and performed structural MRI tests
.
The results show that apathy is related to depression, cognition, education, WMH, LIs, and brain network measurements, and all network measurements are highly correlated (r> 0.

Science: Crack the mystery of "face blindness"! Discover a class of brain cells that specifically recognize familiar faces
Science: Crack the mystery of "face blindness"! Found a class of brain cells that specifically recognize familiar faces2 ,
Researchers from Rockefeller University in the United States published a research paper titled: A fast link between face perception and memory in the temporal pole in the Science journal
.
This new study reveals the mechanism of human face recognition: There are a class of neurons in the temporal poles of the brain that can link face perception with long-term memory
The research team discovered that a small area of the temporal polar region (TP) of the brain may be involved in facial recognition
.
The research team did the following experiment in rhesus monkeys: When rhesus monkeys saw images of familiar faces (which they saw with their own eyes) and unfamiliar faces (which they just saw virtually on the screen), the researchers used Functional magnetic resonance imaging magnified the temporal poles of the brains of two rhesus monkeys and recorded the electrical signals of TP neurons
At the same time, the neurons in the TP area are highly selective.
In rhesus monkeys, the specific performance is: After seeing the image, the TP neurons can quickly distinguish between known and unknown faces, and react to familiar faces than unfamiliar ones.
The face is stronger
.
After quantitatively comparing the specific data, the researchers found that TP neurons responded to familiar faces three times as much as unfamiliar faces! Although the subject actually saw unfamiliar faces on the screen many times
After seeing the image, TP neurons can quickly distinguish between known and unknown faces, and the reaction to familiar faces is stronger than that of unfamiliar faces

Science: Scientists have discovered a new type of memory cells in the brain 3,
Recently, a new study published in the journal Science showed that there is a type of neurons in the temporal poles of the brain that connect facial perception with long-term memory
.
This is not exactly the legendary grandmother neuron-it is not a single cell, but a group of cells that collectively remember the face of the grandmother

.
This is not exactly the legendary grandmother neuron-it is not a single cell, but a group of cells that collectively remember the face of the grandmother
.
This discovery explains for the first time how our brains instill the faces of people we cherish
The research team found that neurons in the TP area are highly selective, and respond more strongly to faces that subjects have seen before than to unfamiliar faces
.
And the speed of these neurons is very fast-it immediately distinguishes between known and unknown faces when processing images

.
These findings constitute the first evidence of mixed brain cells, unlike the legendary grandmother neurons
.
The cells in the TP area behave like sensory cells and have a reliable and rapid response to visual stimuli
.
But they are also like memory cells, only responding to stimuli (familiar faces) that the brain has seen before, reflecting changes in the brain due to past experiences

The study analyzed brain imaging data
from nearly 6,000 9- and 10-year-old children .
Studies have found that physical activity is related to a more organized, robust and flexible brain network
.
The more physical activity, the more the brain is good
.
Being active for at least 60 minutes multiple times a week has a wide range of positive effects on brain circuits
.
Children who engage in high-level physical activities have shown beneficial effects on brain circuits in multiple areas that are essential for learning and reasoning
.
These include attention, sensory and motor processing, memory, decision-making, and executive control (the ability to plan, coordinate, and control actions and behaviors)

Before puberty, many brain functions are still developing, and they can be altered by many risk factors
.
The results show that physical activity has a positive protective effect on brain regions
.
In contrast, increased BMI tends to adversely affect the same brain circuits
.
However, regular physical activity reduces these negative effects

Nat Commun: Born in sorrow and dying in comfort, a stimulating environment will keep the brain young
Nat Commun: Born in sorrow, dying in comfort, and stimulating environment will keep the brain young 5, 5,
Recently, researchers from the Regenerative Therapy Center of the Technical University of Dresden, Germany, published a study in the journal Nature Communications, a subsidiary of Nature
.
Through single-nucleotide resolution whole-genome DNA methylation sequencing, it is proved that the high stimulation environment can also restore a large number of age-related DNA methylation changes in the brain hippocampus, indicating that the high stimulation environment can make the brain's memory control center hippocampus Keep your body young
.
This also explains why an active, diverse life helps maintain mental health in old age
.
.
The research team conducted research in mice.
They let two groups of mice grow up in different environments.
One group grew up in a stimulating environment with various toys and tunnel tubes, while the other group did not
.
It was found that those mice that grew up in a stimulating environment had less decline in their DNA methylation levels as they got older
.
In mice that grew up in a low-stimulus environment, their DNA methylation levels decreased more significantly
.
These changes in DNA methylation levels will not affect genetic information, but they will affect whether a gene is activated or the level of activation
.
.
In mice that grew up in a low-stimulus environment, their DNA methylation levels decreased more significantly
.
These findings provide a potential mechanism: positive interaction with the environment can support and promote brain function throughout the magical cycle
