Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct ‘fight or flight’ and ‘rest and digest’ circuits. These results explain how mental states can affect the gut, and present new ways to treat gastrointestinal problems.
Response of dozens of pain-promotion centers is dampened by single OFF switch.
Researchers also found preliminary evidence that ovarian hormones may modulate the differential response in women and may be related to different levels of estrogen.
Veteran players of ‘Mozak’ are pitted against Allen Institute researchers — well-versed in neuroscience but new to the online game — in a work-and-game-at-home challenge.
Switch in chemical messaging is key prelude to motor skill acquisition according to research
New research has found that a subset of retinal neurons sends inhibitory signals to the brain. Before, researchers believed the eye only sends excitatory signals.
A key target for treating stress-related disorders such as panic disorder and PTSD is what this neural circuit could become.
Study finds involuntary movements caused by dopamine replacement therapy can be alleviated through suppression of RasGRP1.
Neurobiologists at KU Leuven have discovered how the signalling molecule Neuromedin U plays a crucial role in our learning process. The protein allows the brain to recall negative memories and, as such, learn from the past. The findings of their study on roundworms have been published in the journal Nature Communications.
Compared to others, different personality traits exist in individuals with social anxiety disorder. According to a new study from Uppsala University, Emotional instability and introversion are hallmarks.
Brain and heart constantly communicate. For example, signals from the brain make sure that the heart beats faster when we encounter a dangerous situation. The heart slows down when we relax. Interestingly, vice versa – even though the underlying mechanisms are unclear, the heartbeat also affects the brain. It has now been identified by researchers at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig and Berlin School of Mind & Brain that two mechanisms underpinning how the heart influences our perception, the brain, and how these mechanisms differ between individuals.
The function of a special group of nerve cells which are found in the eye and which sense visual movement have been discovered by researchers from Aarhus University. A completely new understanding of how conscious sensory impressions occur in the brain has been acquired through the study. The development of targeted and specific forms of treatment in the future for diseases which impact the nervous system and its sensory apparatus, such as dementia and schizophrenia, needs this kind of insight.
Using a mouse model, adult neurons in corticospinal injuries begin a natural regeneration process by reverting back to an embryonic state and that regeneration is sustained by a surprising gene.
A Novel Role for Dopamine That Impacts Gene Expression Related to Cocaine Abuse Is Discovered By Mount Sinai Researchers
A new role for the brain chemical dopamine that is independent of classic neurotransmission has been discovered by scientists. The new role seems to be vital to changes in gene expression connected to chronic exposure to, or abuse of, cocaine.
Research has shown how stress changes the structure of the brain and reveals a potential therapeutic target to the prevent or reverse it. Led by Si-Qiong June Liu, MD, PhD, Professor of Cell Biology and Anatomy at LSU Health New Orleans School of Medicine, the findings are published in JNeurosci.
Why Parkinson’s disease and other neurological disorders impact one side of the body before the other is explained in recent findings.
Creativity is one of humanity’s most distinctive abilities and enduring mysteries. Innovative ideas and solutions have enabled our species to survive existential threats and thrive. Yet, creativity cannot be necessary for survival because many species that do not possess it have managed to flourish far longer than humans. So what drove the evolutionary development of creativity?
