Study identifies a pathway involving astrocytes that help explain why some with multiple sclerosis experience seizures.
The meaning of "happiness" varies greatly, depending on where in the world a person lives.
Study finds olfaction plays a significant role in the motivation to exercise. Mice who were "high runners" developed genetic differences in their olfactory systems that caused them to perceive smells differently than more sedentary mice.
PBDEs, common flame retardants found on household furniture, caused an increased risk of diabetes in mice only exposed to the chemicals through their mother's milk. In addition to increased glucose intolerance, researchers also noted higher levels of endocannabinoid in the livers of the offspring of mice exposed to PBDEs.
Alterations in the excitation and inhibition balance is regulated in the developing brain by astrocytes via the ephrin-B1 protein. The loss of astrocytic ephrin-B1 alters the E/I balance by reducing inhibition, resulting in hyperactivity of neural circuits. The hyperactivity results in reduced sociability in mice.
Twin study reveals how we adapt to aging may be genetically influenced. Individual differences in blood DNA methylation are partly heritable later in life and longitudinally across a decade, researchers report.
Researchers have identified a mechanism triggered at neuron birth to intrinsically decrease apoptosis. When the genetic regulation is halted, continuous neuronal survival is disrupted, leading to a decrease in animal survival.
Mouse study pinpoints the precise location in the brain where distracting stimuli are blocked, allowing for concentration on specific tasks. The findings could have implications for the treatment of ADHD and schizophrenia.
Study finds the world is a much more similar and unified place than we thought.
Suppressing TLR4 activity following a traumatic brain injury, such as concussion, reduces excitability, and improves working memory performance up-to a month later.
