Golden Ratio Observed In Human Skulls
The Golden Ratio was noted in the human skull dimensions, but not in other mammals. The findings may have important anthropological and evolutionary implications.... Read More...

Transplanted brain stem cells survive without anti-rejection drugs
Researchers have developed a new method to transplant neural stem cells into mice without the need for lifelong anti-rejection medications.... Read More...
High fat diet during pregnancy slows learning in offspring
Maternal exposure to a high-fat diet during pregnancy and lactation can have a lasting, detrimental effect on the cognitive ability and behaviors of their offspring. ... Read More...

Low-carb ‘keto’ or ‘Atkins-style’ diet may modestly improve cognition in older adults
A small scale pilot study reveals adults with mild cognitive impairment may have improved brain function and memory when they switch to a high-fat, low-carb diet.... Read More...
New research shows Parkinson’s disease origins in the gut
A new study adds to the growing body of evidence that Parkinson's disease may start in the gut. Researchers found gut-to-brain propagation of alpha-synuclein spread via the vagus nerve. The study provides a more accurate model of Parkinson's progression and could lead to new treatments to halt or prevent this neurodegenerative disease.... Read More...
Education and intelligence may protect cognition’ but don’t prevent Alzheimer’s disease
Intelligence, education and participating in cognitively challenging tasks may stave off the effects of dementia for longer, but can not protect against the inevitable Alzheimer's pathology in those at risk.... Read More...
Brain changes linked with Alzheimer’s up to 30 years before symptoms appear
Researchers have identified average levels of biological and anatomical brain changes associated with Alzheimer's disease over thirty years before symptoms appear. In those with genetic risk factors for Alzheimer's, researchers found changes in cognitive performance up to 15 years before becoming symptomatic. Changes in Tau levels in the cerebral spinal fluid appeared up to 34 years before dementia symptoms occurred, and physical changes to the medial temporal lobe were apparent up to 9 years before cognitive impairment was apparent....

Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia
Sulforaphane, a compound derived from broccoli sprouts, may be a useful new treatment for those suffering from schizophrenia. In a recent set of animal and human studies, researchers characterized novel chemical imbalances in the brain related to glutamate. Levels of glutamate, they discovered, can be altered by administering sulforaphane.... Read More...
Restoring brain function in mice with symptoms of Alzheimer’s disease
Senolytic drugs administered to mice reduced senescent cells around amyloid plaques by more than 90% and decreased neuroinflammation by 50%. Mice treated with the drug combination also showed improvements in spatial memory, compared to other Alzheimer's model mice who received no treatment. The findings could have positive implications for the treatment of Alzheimer's disease in people with the condition.... Read More...
Study suggests overdiagnosis of schizophrenia
Researchers provide evidence schizophrenia may be overdiangosed in patients experiencing anxiety and other mood disorders. ... Read More...
Psychedelic drug MDMA may reawaken ‘critical period’ in brain to help treat PTSD
MDMA, a psychedelic drug, has successfully been used to reopen the 'critical period' of learning the reward values of social behaviors. Researchers report, in mature mice given MDMA, oxytocin triggers signaling in synapses that help encode social learning and memory, a process that does not usually occur in older animals. The findings could help in the development of treatments for PTSD and other disorders.... Read More...
