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.

Antibiotics: do they affect contraceptives?

NPS MedicineWise has released information for consumers about taking antibiotics when also using hormonal contraceptives, explaining that there are only two antibiotics that affect how hormonal contraceptives work.

Neuroscientists try to decipher precisely how human brain constructs our sense of self

Ancient Greek philosophers considered the ability to "know thyself" as the pinnacle of humanity. Now, thousands of years later, neuroscientists are trying to decipher precisely how the human brain constructs our sense of self.

Viewpoints: Medicare as a 401(K) plan; Health doublespeak

Older adults are understandably anxious about the political sniping over the future financing of Medicare. That is precisely the intention of the presidential campaigns. Yet the cross-fire over who will cut Medicare by how much sidesteps a critical issue about the future of our medical care: If we must ration our care to hold down costs in the future, how can we do it in a fair, efficient and transparent way?

Signs of epilepsy in childhood

When parents hear the word "epilepsy," it typically triggers images of severe seizures – the ones that are easy to identify, involving a child falling, getting stiff and shaking all over. But the truth is, there are over 300,000 children and teens in the U.S. with epilepsy, and not all of them display such obvious signs of their medical condition.

New imaging technique reveals the brain's continuous renovation

Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell.

Preemptive cognitive training can help the brain function normally later in life

Preemptive cognitive training—an early intervention to address neuropsychiatric deficiencies—can help the brain function normally later in life, a team of researchers has found through a series of experiments on laboratory rats.

Study might help solve the biggest mystery of Parkinson’s

The recent discoveries that α-Synuclein(α-Syn) protein, a central player in Parkinson´s disease (PD) brain destruction, could not only pass from one neuron to another but also exist outside neuronal cells has led to major rethink on the disease.

Two Penn Medicine hospitals receive Primary Stroke Center certification from The Joint Commission

Two Penn Medicine hospitals have received Primary Stroke Center certification from The Joint Commission for efforts to achieve long-term success in improving outcomes for stroke patients.

New study: Reasoning training does alter brain connections

Intensive preparation for the Law School Admission Test (LSAT) actually changes the microscopic structure of the brain, physically bolstering the connections between areas of the brain important for reasoning, according to neuroscientists at the University of California, Berkeley.

Simple eye tracking test could hold key to early Alzheimer's diagnosis

A simple eye tracking test could hold the key to earlier Alzheimer's diagnosis, according to new research published today in the Journal of the American Aging Association.

Alcohol can cause more than one pattern of birth defects

A collaborative research effort by scientists at the University of North Carolina School of Medicine, Duke University, and University College of London in the UK, sheds new light on alcohol-related birth defects.

New medical technology improves image quality and reduces radiation

Particle physicists have developed a new medical technology that combines PET and MRI in one. Benefit: Improved image quality and less radiation.

Researchers report how Alzheimer's protein deposits disrupt signalling between nerve cells

How abnormal protein deposits in the brains of Alzheimer's patients disrupt the signalling between nerve cells has now been reported by researchers in Bochum and Munich, led by Dr. Thorsten M-ller from the Medizinisches Proteom-Center of the Ruhr-Universit-t, in the journal Molecular and Cellular Proteomics. They varied the amount of APP protein and related proteins associated with Alzheimer's disease in cell cultures, and then analysed how this manipulation affected other proteins in the cell.

Musical memory organized at least partially independent of the hippocampus

Together with his team, Prof. Christoph Ploner, director of the Department of Neurology at the Virchow campus, examined a professional cellist who suffered from encephalitis caused by a herpes virus. As a result of the inflammation, the patient developed serious disturbances in memory. Both his memory for the past (retrograde amnesia), as well as the acquisition of new information (anterograde amnesia) were affected.

OBI’s Oxycyte improves imaging of penumbra following acute ischemic stroke

Oxygen Biotherapeutics, Inc., announced today that recent research conducted by its partner, Aurum Biosciences, Glasgow, Scotland, has shown that Oxycyte, OBI's proprietary perfluorocarbon-based intravenous emulsion, improves imaging of the penumbra following acute ischemic stroke in a rat model.

Reasoning and behavioral control dependent on different regions of frontal lobes

The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes-which are located just behind and above the eyes-can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech) recently teamed up with researchers at the world's largest registry of brain-lesion patients.

Working memory capacity in patients with Parkinson's can be improved with sleep

People with Parkinson's disease performed markedly better on a test of working memory after a night's sleep, and sleep disorders can interfere with that benefit, researchers have shown.

Scientists unravel how brain cells encode pronunciation of individual vowels in speech

Diagnosed with Lou Gehrig's disease at 21, British physicist Stephen Hawking, now 70, relies on a computerized device to speak. Engineers are investigating the use of brainwaves to create a new form of communication for Hawking and other people suffering from paralysis. -Daily Mail

Interhemispheric coordination reduced in schizophrenia

Results from a US study show that patients with schizophrenia have significantly decreased interhemispheric coordination compared with mentally healthy individuals.

Neurally-interfaced hand prosthesis re-establishes communication between nervous systems

Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.
