Researchers report that #hearing_impairment is associated with accelerated #cognitive decline with #age, though the impact of mild hearing loss may be lessened by higher education.
#Exercise training alters #brain blood flow and improves cognitive performance. A study showed that exercise was associated with improved brain function in a group of adults diagnosed with mild #cognitive impairment and a decrease in the blood flow in key brain regions
High levels of a satiety hormone could decrease a person's chance of developing #Alzheimer's disease. For individuals who have higher levels of the hormone, their chance of having mild cognitive impairment or Alzheimer's disease decreased by 65%
Human beings, like other animals, possess an enormous #learning_capacity that allows for the apprehension of new #sensory_information to master new skills or to adapt to an ever-changing environment.
Researchers have developed a new combination of technologies that allows them to identify the functional properties of individual #synapses that link the two #hemispheres and determine how they are arranged within a neuron's dendritic field.
Researchers have shown that cells from mice that have been induced to grow into #nerve_cells using a previously published method have #molecular_signatures matching neurons that developed naturally in the #brain.
If mice lose their #vision immediately after birth due to a genetic defect, this has a considerable impact, both on the #organization of the cerebral cortex and on #memory_ability.
Using a common type of #brain_scan, researchers programmed a machine-learning algorithm to diagnose early-stage #Alzheimer's disease about six years before a clinical diagnosis is made– potentially giving doctors a chance to intervene with treatment.
Researchers have shown in mice that #obesity increases the level of '#zombie' or senescent cells in brain, and that those cells, in turn, are linked to #anxiety. When #senolytic drugs are used to clear those cells, the anxious behaviors in the mice dissipate.
A new study reports the neurons that focus on coarse visual details could change to prefer finer details under different conditions. The findings shed new light on the neural mechanism that helps shape our perception of the world.
#Spatiotemporal propagation of frontal activity supports #memory formation in children as young as 6 years of age, and show how adjacent frontal sub-regions follow dissociable developmental trajectories.
Minimally invasive intravascular electrodes chronically implanted via the superior sagittal sinus can stimulate the motor cortex of sheep, and elicit muscular activity.
On increasing the excitability of a subpopulation of hippocampal inhibitory neurons, certain behavioral symptoms associated with schizophrenia can be suppressed.
Researchers have found that young adults who experienced repetitive mild traumatic brain injury (#mTBI), or concussions, can experience persistent cognitive changes as well as altered brain activity.
A non-invasive technology that detects when nerve cells fire, based on changes in shape, can be used to observe nerve activity in light-accessible parts of body such as eye, which would allow physicians to quantitatively monitor visual function at cellular level
New research has identified #neurons that play a role in how people recognize errors they make, a discovery that may have implications for the treatment of conditions including #obsessive_compulsive_disorder and #schizophrenia.
