Thalamus News and Research

RSS

The Thalamus is an area of the brain that helps process information from the senses and transmit it to other parts of the brain.

The head plays key role in tiring endurance performances

Researchers from the University of Zurich have now studied in detail what sportsmen and women know from experience: The head plays a key role in tiring endurance performances.

Scientists seek to prove beta oscillations of the cortex

Before she could seek to convince the world that her computer model of a key brain circuit explains a fundamental, 80-year-old mystery of neuroscience with potential relevance to Parkinson's disease, Stephanie Jones sought to convince Christopher Moore.

Study uses fMRI to assess changes in brain after exercise intervention

Areas of the brain responsible for pain processing and cognitive performance changed in fibromyalgia patients who exercised following a medication holiday, say researchers from Georgetown University Medical Center. They say the changes indicate brain functioning is more streamlined after an exercise intervention because less of the brain-s resources is devoted to processing bothersome fibromyalgia perceptions such as pain.

Pitt mathematicians to target symptoms of Parkinson's disease

University of Pittsburgh mathematicians have been collaborating with Pitt's School of Medicine to find ways to stop the symptoms of Parkinson's disease, thanks in part to a four-year, $1.86 million grant from the National Science Foundation (NSF) and a five-year $1.2 million grant from the National Institutes of Health.

AiC: Health Research receives U.S. Army grant for neuroimaging studies of human performance

The Arlington Innovation Center: Health Research (AiC: Health Research), of Virginia Tech's National Capital Region, has been awarded a $1.5 million cooperative research and development agreement from the U.S. Army for neuroimaging studies of human performance.

MR-guided focused ultrasound may effectively control essential tremor

In a presentation at the Congress of Neurological Surgeons today, University of Virginia neurosurgeon W. Jeffrey Elias, MD reported that preliminary results of a pilot clinical trial indicate that MR-guided focused ultrasound has the potential to safely and effectively control essential tremor (ET), a common neurological condition that affects 10 million Americans.

Scientists discover two opposing neuronal regulatory circuits for generation, elimination of fear

Emotional balance is regulated by molecular factors behind stress response. When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety.

Scientists identify brain-circuit defect that triggers absence seizures

Researchers at the Stanford University School of Medicine have identified a brain-circuit defect that triggers absence seizures, the most common form of childhood epilepsy.

Patients with MTBI exhibit abnormal functional connectivity in the thalamus

A new study has found that patients with mild traumatic brain injury (MTBI) exhibit abnormal functional connectivity in the thalamus, a centrally located relay station for transmitting information throughout the brain.

MR-guided focused ultrasound effective for treating essential tremor

The last ten years have been challenging for Billy R. Williams of Fort Valley, Virginia. The former Pentagon employee, who survived the 9/11 terrorist attack, has suffered from essential tremor, a progressive and debilitating neurological disorder.

Scientists discover how odors are detected and processed by brain

Researchers seeking to unravel the most ancient yet least understood of the five senses - smell - have discovered a previously unknown step in how odors are detected and processed by the brain.

Noninvasive MR-guided focused ultrasound successfully treats essential tremor

A new chapter in medical history opened days ago when noninvasive MR-guided focused ultrasound was used to successfully treat a patient with essential tremor (ET), a progressive neurological disorder that affects millions of people worldwide and causes involuntary shaking of the hands, head, face, eyelids, voice or other muscles.

Sanfilippo syndrome compromises blood-brain barrier, leads to brain damage

A study into the effects of Sanfilippo Syndrome type B (MPS III B) has found that the barrier responsible for protecting the brain from the entry of harmful blood-borne substances is structurally and functionally damaged by the devastating disease. University of South Florida researchers identified damage in specific brain structures involved in the pathology of MPS III B, one of four Sanfilippo syndromes, all of which are inherited diseases of metabolism.

New study provides insight into brain activity of depressed women responding to crying infants

Mothers who are depressed respond differently to their crying babies than do non-depressed moms. In fact, their reaction, according to brain scans at the University of Oregon, is much more muted than the robust brain activity in non-depressed moms.

Deep brain stimulation therapy promising against severe OCD

When obsessive-compulsive disorder is of crippling severity and drugs and behavior therapy can't help, there has been for just over a year a thread - or rather a wire - of hope. By inserting a thin electrode deep into the brain, doctors can precisely deliver an electrical current to a cord of the brain's wiring and soften the severity of the symptoms. "Deep brain stimulation" therapy for OCD won Food and Drug Administration approval in 2009 for extreme cases under its humanitarian device exemption.

Mg significantly reduces neonatal brain injury linked with maternal inflammation, infection

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, researchers will present findings that showed that in rats, the use of magnesium sulfate significantly reduced the neonatal brain injury associated with maternal inflammation or maternal infection.

General anaesthesia brings reversible coma and not sleep: Study

Anaesthesia has been one of the greatest gifts of science and use of general anaesthesia is a routine part of surgical operations at hospitals and medical facilities around the world. However precise biological mechanisms of the drugs’ effects on the brain are only now being analyzed. In a review article published this week in the New England Journal of Medicine, scientists have tried to analyze a range of disciplines, including neuroscience and sleep medicine to understand how anaesthesia actually works.

General anesthesia's similarities with and differences from sleep and coma

The use of general anesthesia is a routine part of surgical operations at hospitals and medical facilities around the world, but the precise biological mechanisms that underlie anesthetic drugs' effects on the brain and the body are only beginning to be understood. A review article in the December 30 New England Journal of Medicine brings together for the first time information from a range of disciplines, including neuroscience and sleep medicine, to lay the groundwork for more comprehensive investigations of processes underlying general anesthesia.

Neuroscientists say that general anesthesia is a reversible coma

The brain under general anesthesia isn't "asleep" as surgery patients are often told -- it is placed into a state that is a reversible coma, according to three neuroscientists who have published an extensive review of general anesthesia, sleep and coma, in the Dec. 30 issue of The New England Journal of Medicine.

Closer to restoring vision loss due to optic nerve damage

Damage to the optic nerve, connecting the eye with the brain, is a major cause of blindness. The most common culprit is glaucoma, estimated to affect more than 4 million Americans. There is currently no way to restore the lost vision, because the optic nerve, like other nerves in the mature central nervous system (CNS), cannot regenerate. Now, scientists at Children's Hospital Boston report achieving the greatest regeneration to date in the mammalian optic nerve.
