Novel method to measure neuron response to transcranial magnetic stimulation of the brain

Novel method to measure neuron response to transcranial magnetic stimulation of the brain

Engineers and neuroscientists at Duke University have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS -- a procedure used to treat psychiatric disorders -- and optimize its use as a therapeutic treatment. [More]
Light-sensitive molecule enables noninvasive silencing of neurons

Light-sensitive molecule enables noninvasive silencing of neurons

Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled. [More]

Increasing clearance of ALS misfolded protein from neurons improves their survival

In work supported by The ALS Association, researchers have shown that increasing the clearance of misfolded protein from neurons improves their survival. The study was published today in the journal Nature Chemical Biology. [More]
Researchers give new, unprecedented 3-D view of most important brain receptors

Researchers give new, unprecedented 3-D view of most important brain receptors

Researchers with Oregon Health & Science University's Vollum Institute have given science a new and unprecedented 3-D view of one of the most important receptors in the brain - a receptor that allows us to learn and remember, and whose dysfunction is involved in a wide range of neurological diseases and conditions, including Alzheimer's, Parkinson's, schizophrenia and depression.

Neuroscientists can control muscle movement by applying optogenetics

For the first time, MIT neuroscientists have shown they can control muscle movement by applying optogenetics - a technique that allows scientists to control neurons' electrical impulses with light - to the spinal cords of animals that are awake and alert. [More]

Agricultural pesticides raise risk of autism in unborn children

Agricultural pesticides raise risk of autism in unborn children

Pregnant women who lived in close proximity to fields and farms where chemical pesticides were applied experienced a two-thirds increased risk of having a child with autism spectrum disorder or other developmental delay, a study by researchers with the UC Davis MIND Institute has found. The associations were stronger when the exposures occurred during the second and third trimesters of the women's pregnancies. [More]
Researchers explore genetic and cellular mechanisms of retinal development

Researchers explore genetic and cellular mechanisms of retinal development

The circuitry of the central nervous system is immensely complex and, as a result, sometimes confounding. When scientists conduct research to unravel the inner workings at a cellular level, they are sometimes surprised by what they find. [More]
Researchers explore how neurons establish spatial polarity and direction in tissues, organs

Researchers explore how neurons establish spatial polarity and direction in tissues, organs

The question of how neurons and their axons establish spatial polarity and direction in tissues and organs is a fundamental question of any organism or biological system. [More]
Weizmann Institute scientists 'fingerprint' a culprit in depression and anxiety disorders

Weizmann Institute scientists 'fingerprint' a culprit in depression and anxiety disorders

According the World Health Organization, such mood disorders as depression affect some 10% of the world's population and are associated with a heavy burden of disease. That is why numerous scientists around the world have invested a great deal of effort in understanding these diseases. Yet the molecular and cellular mechanisms that underlie these problems are still only partly understood. [More]

Researchers develop new model of neural network

A newly-developed, highly accurate representation of the way in which neurons behave when performing movements such as reaching could not only enhance understanding of the complex dynamics at work in the brain, but aid in the development of robotic limbs which are capable of more complex and natural movements.

New study on transmitophagy process may help treat diverse disorders

New study on transmitophagy process may help treat diverse disorders

It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria - the tiny power plants inside cells - to supporting glial cells called astrocytes for disposal.

New hope for people suffering from depression

New hope for people suffering from depression

There is new hope for people suffering from depression. Researchers have identified a compound, hydroxynorketamine (HNK), that may treat symptoms of depression just as effectively and rapidly as ketamine, without the unwanted side effects associated with the psychoactive drug, according to a study in the July issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists- (ASA-).

Human mind can rapidly absorb new information by synchronization of brain waves

The human mind can rapidly absorb and analyze new information as it flits from thought to thought. These quickly changing brain states may be encoded by synchronization of brain waves across different brain regions, according to a new study from MIT neuroscientists. [More]

New mechanism explains novel aspects of how wiring of neurons in brain works

How neurons are created and integrate with each other is one of biology's greatest riddles. Researcher Dietmar Schmucker from VIB-KU Leuven unravels a part of the mystery in Science magazine. [More]
Chronic sleep loss can cause certain neurotoxic molecules to permeate into brain tissue

Chronic sleep loss can cause certain neurotoxic molecules to permeate into brain tissue

The longer the insomnia, junctions of cerebral blood vessels begin to degrade. In search of the answer to why do we sleep, research conducted at the Mexican Metropolitan Autonomous University (UAM) revealed that chronic sleep loss can cause certain neurotoxic molecules, which normally circulate in the blood, to be transported to the central nervous system and interfere with the function of neurons.
