Short bout of exercise enhances brain function
Short bursts of exercise, equivalent to a pick-up game of basketball, boosts the function of a gene that increases dendritic spines in the hippocampus, helping to improve memory and learning.... Read More...
Stem cells reprogrammed into neurons could reveal drugs harmful to pregnancy
A new experimental system which uses embryonic stem cells reprogrammed into neurons has the potential to assess the pathogenic effects of a drug on brain development.... Read More...
Neurons’ “antennae” are unexpectedly active in neural computation
When the soma of specific neurons is active, the dendrites of the same neuron are also active, even when animals are not engaged in a cognitively demanding task. ... Read More...
New research offers insight into the proteins in the brain that detect cannabis
The secretory pathway delivery of cannabinoid type 1 receptor is axonally based, and surface expressed CB1R is more stable in axons than dendrites.... Read More...
Vitamin D study sheds light on immune system effects
Vitamin D causes dendritic cells to produce more CD31, hindering the activation of T cells. The study sheds light on how vitamin D deficiency regulates the immune system and can lead to autoimmune diseases, like multiple sclerosis.... Read More...
Ketamine reverses neural changes underlying depression-related behaviors: Mouse study
The formation of prefrontal cortex dendritic spine formation sustains the remission of depressive related symptoms and behaviors following ketamine treatment by restoring lost spines. ... Read More...
Unexpected Place for Learning and Memory in the Brain
A new study reveals the somatosensory cortex plays a complex role in memory and reward learning. ... Read More...
Synaptic Logic for Connections Between Two Brain Hemispheres Discovered
Researchers have developed a new technique that helps identify the functional properties of individual synapses that link the two hemispheres of the brain.... Read More...
Cannabis Exposure and Stress in Adolescence Can Lead to Anxiety Disorders in Adults
A new study reports exposure to cannabis and stress during the teenage years may result in an increased risk of developing anxiety disorders later in life. ... Read More...
How the Brain Enables Us to Rapidly Focus Attention
Researchers have identified a mechanism within the cholinergic system that underlies our ability to rapidly focus attention.... Read More...
Developing Brains of Preterm Babies Benefit From Caffeine Therapy
A new study reveals caffeine therapy appears to have benefits for healthy brain development in children born prematurely. Researchers report preterm babies given caffeine therapy had better cognitive scores, reduced odds of cerebral palsy and less hearing impairments as toddlers. ... Read More...
