Researchers identify distinctive brain patterns associated with general anesthesia drug

Since the mid-1800s, doctors have used drugs to induce general anesthesia in patients undergoing surgery.

Scientists discover how to detect abnormal brain rhythms associated with Parkinson's

A team of scientists and clinicians at UC San Francisco has discovered how to detect abnormal brain rhythms associated with Parkinson's by implanting electrodes within the brains of people with the disease.

Brown University develops new implantable and rechargeable wireless brain sensor

A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects.

Brain functional connectivity differs between unipolar and bipolar depression

Patients with bipolar depression differ from their peers with unipolar depression in having stronger functional connectivity in the right posterior cingulate cortex, US study findings indicate.

Researchers discover novel way to image the entire brain's glymphatic pathway

A novel way to image the entire brain's glymphatic pathway, a dynamic process that clears waste and solutes from the brain that otherwise might build-up and contribute to the development of Alzheimer's disease, may provide the basis for a new strategy to evaluate disease susceptibility, according to a research paper published online in The Journal of Clinical Investigation.

Individuals with psychogenic disease do have brains that function differently

Psychogenic diseases, formerly known as 'hysterical' illnesses, can have many severe symptoms such as painful cramps or paralysis but without any physical explanation. However, new research from the University of Cambridge and UCL (University College London) suggests that individuals with psychogenic disease, that is to say physical illness that stems from emotional or mental stresses, do have brains that function differently.

Evidence could prove that humans have unique cortical brain networks

Our ancestors evolutionarily split from those of rhesus monkeys about 25 million years ago. Since then, brain areas have been added, have disappeared or have changed in function. This raises the question, 'Has evolution given humans unique brain structures?'. Scientists have entertained the idea before but conclusive evidence was lacking. By combining different research methods, we now have a first piece of evidence that could prove that humans have unique cortical brain networks.

CB2 receptors might serve as potential therapeutic targets for cerebral ischemia

A new study published in the March issue of The American Journal of Pathology suggests that cortical type 2 cannabinoid (CB2) receptors might serve as potential therapeutic targets for cerebral ischemia.

Researchers uncover neurological basis of speech motor control

A team of researchers at UC San Francisco has uncovered the neurological basis of speech motor control, the complex coordinated activity of tiny brain regions that controls our lips, jaw, tongue and larynx as we speak.

Researchers succeed in developing artificial neuronal network

This technological prowess was made possible by the development of a "simplified artificial brain" that reproduces certain types of so-called "recurrent" connections observed in the human brain.

Brain damage can persist for decades after original head trauma

As the National Football League braces for lawsuits by 4000 former players alleging the league failed to protect them from the long-term consequences of concussions, game-changing research by a leading Canadian researcher shows damage to the brain can persist for decades after the original head trauma.

Infrared signaling could create sense of touch in artificial limbs

Rats can't usually see infrared light, but they have "touched" it in a Duke University lab. The rats sensed the light as a sensation of touch after Duke neurobiologist Miguel Nicolelis and his team fitted the animals with an infrared detector wired to electrodes implanted in the part of the mammalian brain that processes information related to the sense of touch.

'Primitive' reflexes may involve more sophisticated brain function than previously thought

Supposedly 'primitive' reflexes may involve more sophisticated brain function than previously thought, according to researchers at Imperial College London.

Mindfulness practitioners gain enhanced control over sensory cortical alpha rhythms

Why does training in mindfulness meditation help patients manage chronic pain and depression? In a newly published neurophysiological review, Brown University scientists propose that mindfulness practitioners gain enhanced control over sensory cortical alpha rhythms that help regulate how the brain processes and filters sensations, including pain, and memories such as depressive cognitions.

Menopausal brain changes support estrogen’s protective role in schizophrenia

Researchers have found morphological differences between pre- and postmenopausal women with schizophrenia that support a protective role for estrogen in the psychiatric disorder.

Study shows effects of maternal obesity on fetuses

In a study to be presented on February 15 between 8 a.m. and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, California, researchers from Tufts Medical Center will present findings showing the effects of maternal obesity on a fetus, specifically in the development of the brain.

Study finds reason why patients with chronic pain often suffer from impaired short -term memory

A group of Portuguese researchers from IBMC and FMUP at the University of Porto has found the reason why patients with chronic pain often suffer from impaired short -term memory.

Familial psychosis risk linked to prefrontal dopamine dysfunction

People at familial risk for psychosis have attenuated dopamine stress modulation in the ventromedial prefrontal cortex, according to a recent in vivo imaging study.

Researchers identify an exceptional mouse model of schizophrenia

Researchers at the Institute for Comprehensive Medical Science, Fujita Health University and the National Institute for Physiological Sciences, Japan, along with colleagues from 9 other institutions, have identified an exceptional mouse model of schizophrenia.

Study findings suggest physical and pharmacological solutions for human stroke victims

Johns Hopkins researchers have found that mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body, if the rodents are quickly subjected to physical conditioning that rapidly "rewires" a different part of the brain to take over lost function.
