The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Table-top solid-state laser system cuts brain tissue with unprecedented precision

Researchers from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) were involved in the development of a table-top solid-state laser system that could cut brain tissue with unprecedented precision. The achievement is a result of an interdisciplinary EU project that involved partners from seven European countries.

Thioridazine drug successfully kills human cancer stem cells

A team of scientists at McMaster University has discovered a drug, thioridazine, successfully kills cancer stem cells in the human while avoiding the toxic side-effects of conventional cancer treatments.

Fever during pregnancy associated with autism or developmental delay

A team of UC Davis researchers has found that mothers who had fevers during their pregnancies were more than twice as likely to have a child with autism or developmental delay than were mothers of typically developing children, and that taking medication to treat fever countered its effect.

New diagnostic approach for Lyme disease

George Mason University researchers can find out if a tick bite means Lyme disease well before the bite victim begins to show symptoms.

UCSF receives $20M Sandler Foundation gift for neuroscience research and care

UCSF has received a challenge gift of $20 million from the Sandler Foundation that will provide major support for the university's groundbreaking research and clinical care efforts regarding neurological diseases.

UCSF scientists aim to use embryonic stem cells for treatment of neuropathic pain

Chronic pain, by definition, is difficult to manage, but a new study by UCSF scientists shows how a cell therapy might one day be used not only to quell some common types of persistent and difficult-to-treat pain, but also to cure the conditions that give rise to them.

Changes in sensory experience can cause massive rewiring of the brain

Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition.

Experiencing strong emotions synchronises brain activity across individuals

Experiencing strong emotions synchronises brain activity across individuals, research team at Aalto University and Turku PET Centre in Finland has revealed.

PERK protein necessary to maintain behavioral flexibility

Researchers have identified a protein necessary to maintain behavioral flexibility, which allows us to modify our behaviors to adjust to circumstances that are similar, but not identical, to previous experiences. Their findings, which appear in the journal Cell Reports, may offer new insights into addressing autism and schizophrenia—afflictions marked by impaired behavioral flexibility.

UofL receives Helmsley Charitable Trust grant to develop technology for paralyzed people

The University of Louisville has received $6.3 million from the Leona M. and Harry B. Helmsley Charitable Trust to support research in the Department of Neurological Surgery and the Kentucky Spinal Cord Injury Research Center at UofL developing the next generation of technology to help paralyzed people regain movement in their limbs and enhance their quality of life.

New method can screen for bacterial genes that are expressed during meningitis

Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromised patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world.

Human olfactory bulb differs from that of other mammals

Research from Karolinska Institutet in Sweden shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals.

Scientists discover how microglia detect the site of injury

Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered exactly how microglia detect the site of injury, thanks to a relay of molecular signals.

Personality traits may also be part of the longevity genes mix

"It's in their genes" is a common refrain from scientists when asked about factors that allow centenarians to reach age 100 and beyond. Up until now, research has focused on genetic variations that offer a physiological advantage such as high levels of HDL cholesterol. But researchers at Albert Einstein College of Medicine and Ferkauf Graduate School of Psychology of Yeshiva University have found that personality traits like being outgoing, optimistic, easygoing, and enjoying laughter as well as staying engaged in activities may also be part of the longevity genes mix.

Alpha-2 agonists decrease postoperative consumption of opioid drugs

A study from researchers at Geneva University Hospital, Geneva, Switzerland, provides evidence that use of alpha-2 agonists alongside opioids in surgical patients decreased opioid use by 25-30 percent. Even though opioid use was less, these patients reported slightly less pain after surgery.

Study sheds light on role of microglia in the normal brain

Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change.

Optogenetic Therapies for Vision workshop to be held on June 1

The Foundation Fighting Blindness and Massachusetts Eye and Ear will host the Optogenetic Therapies for Vision workshop on Friday, June 1, from 8 a.m.-6 p.m., in Boston.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

Omega-3 fatty acids may provide more benefits for elderly people with Alzheimer's

According to a recent study published online in Neurology, Omega-3 fatty acids, like those found in Omega XL fish oil extract containing DHA and EPA from the New Zealand green-lipped mussel, may provide more benefits for elderly people suffering from Alzheimer's.
