(Medical Xpress) — A group of Australian neuroscientists have been reviewing the results of many studies done over the years regarding the parts of the brain that are thought to be used in different real world scenarios and have found that many of them appear to be involved when people go into what is called a default network – more commonly known as daydreaming, or running on auto-pilot. Their findings suggest, as they write in their paper published in Nature Reviews Neurology, that the default network is tied very closely with the same areas of the brain generally thought of as those used for social skills.
fMRI brain imaging illuminates magic mushrooms’ psychedelic effects
Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two studies being published in scientific journals this week identify areas of the brain where activity is suppressed by psilocybin and suggest that it helps people to experience memories more vividly.
Transcriptional barcoding of retinal cells identifies disease target cells
(Medical Xpress) — By developing a large scale gene expression map for retinal cell types, FMI Neurobiologists have been able to identify the cells in the retina, where the genes causing retinal diseases specifically act. This narrows down the search for a better understanding of the diseases and opens up new avenues for therapeutic approaches.
Study shows how neurons interact, could lead to new treatment for addiction
Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.
Blocking metabolic protein improves movement in animals with amyotrophic lateral sclerosis
Turning off a protein that helps cells balance energy increases animal mobility and reduces the death of nerve cells that control movement in animal models of amyotrophic lateral sclerosis (ALS), according to a study in the January 18 issue of The Journal of Neuroscience. The findings may one day guide new directions for the treatment of the progressive neurodegenerative disorder, for which there is currently no cure.
