Smarter training of neural networks
Researchers report artificial neural networks contain subnetworks that are considerably smaller, yet capable of being trained to make equally accurate predictions. Many subnetworks can learn to make accurate predictions much faster than the original networks.... Read More...
Why visual stimulation may work in fight against Alzheimer’s: Mouse study
Inducing gamma oscillations with visual stimulation via a process known as gamma entrainment using sensory stimuli, or GENUS, was shown to reduce amyloid plaques and phosphorylated tau in mouse models of dementia. Providing GENUS daily during the early stages of neurodegeneration helps preserve neural and synaptic density across multiple brain areas and improves cognitive performance for learning and spatial memory tasks....

Artificial neural networks can be used to drive brain activity
Current deep learning models are able to create images strongly enough to activate specific neurons in the visual cortex. However, researchers say more accurate artificial neural network models should be developed to help produce more accurate control.... Read More...
A comprehensive map of how Alzheimer’s affects the brain
Axon myelination is significantly disrupted in patients with Alzheimer's disease. Researchers also found brain cells of men and women vary significantly in how their genes respond to the neurodegenerative disease.... Read More...
Brain Wave Stimulation May Improve Alzheimer’s Symptoms
Multisensory gamma wave stimulation improves recognition and spatial memory, in addition to reducing amyloid in the auditory cortex and hippocampal CA1 areas of mice. Findings suggest such sensory stimulation boosts hippocampal function and reduces Alzheimer's linked pathologies throughout the neocortex.... Read More...
New MRI Sensor Can Image Activity Deep Within the Brain
Researchers at MIT have developed a new neuroimaging technique that can track signaling processes inside neurons. The MRI sensor will enable researchers to identify the roles neurons play in different types of behavior.... Read More...

Specific Gene Variants May Increase Bipolar Risk
According to researchers, CPG2 is significantly less abundant in the brains of those with bipolar disorder. The findings could help develop new diagnostics and treatment for bipolar disorder.... Read More...
Mapping the Brain at High Resolution
Researchers report a newly developed 3D imaging technique can reveal, more quickly and in greater detail, how neurons connect throughout the brain.... Read More...
The Circuits That Help You Keep Your Cool
Researchers reveal how connections from around the mammalian brain stimulate two key cell types in the locus coeruleus to moderate arousal in two different ways. ... Read More...
Specific Gene Variants May Raise Bipolar Disorder Risk
Researchers report the CPG2 protein is significantly decreased in the brains of people with bipolar disorder and mutations in the SYNE1 gene undermines the expression of CPG2. The study shows how a set of genetic differences in those with bipolar disorder can lead to specific psychological dysfunction in synapses in the brain. The findings could help improve diagnosis of the disorder and help develop new treatments for BD.... Read More...
