Researchers have identified the brain circuits involved in hunger that are influenced by the hormone leptin, the signaling molecule produced by fat cells.
A guideline developed by the American Academy of Neurology recommends immediate brain CT scans to screen certain emergency room patients with seizures.
An overwhelming majority of Americans with memory concerns had not discussed this issue with their doctors despite recent visits.
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells - a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration.
Results of a new study may one day help scientists learn how to enhance a naturally occurring mechanism in the brain that promotes resilience to psychological stress. Researchers funded by the National Institutes of Health's National Institute of Mental Health (NIMH) found that, in a mouse model, the ability to adapt to stress is driven by a distinctly different molecular mechanism than is the tendency to be overwhelmed by stress. The researchers mapped out the mechanisms - components of which also are present in the human brain - that govern both kinds of responses.
Deep brain stimulation (DBS) of the subthalamic nucleus dramatically improves the motor symptoms of Parkinson's disease, but causes cognitive side effects such as impulsivity.
The epilepsy drug lamotrigine is effective in controlling partial seizures when taken once a day as an added therapy.

Mayo Clinic has clarified the methods of diagnosis and optimal management of a rare and little-understood blood vessel disease of the brain and spinal cord.
Extensive neurological research shows that through intensive, repetitive training the brain can change and adapt to a new skill or technique, which is called brain plasticity.
This new brain study constitutes a considerable step forward towards deciphering intentions to perform movements by persons who are paralyzed or are amputees, thus paving the way for creation of better instruments for converting brain activity into actual movements.
The evidence linking amateur boxing and chronic traumatic brain injury is not strong.
A molecular 'recycling plant' permits nerve cells in the brain to carry out two seemingly contradictory functions - changeable enough to record new experiences, yet permanent enough to maintain these memories over time.
Brain imaging is used to describe neural circuits contributing to pedophilia.
New region of brain is responsible for a key auditory process - perceiving "sound space," the location of sounds, even when the listener is not concentrating on those sounds.
Researchers at Dana-Farber Cancer Institute have shown that several cell-growth switches are simultaneously overactive in many brain tumors and other solid tumors.
Frequent mobile phone users demonstrated slowed Brain function.
Recent data from a Phase II study of Accera's lead compound Ketasyn (AC- 1202) in age-associated memory impairment showed that Ketasyn has a positive and clinically meaningful effect on memory in older adults.
People with epilepsy who experience multiple auras, sensations such as a cold breeze or bright light before they have a seizure, may be good candidates for epilepsy surgery.
We could soon be able to diagnose the onset of many brain diseases by analysing the tiny magnetic fields produced by neuron activity in the brain.
Deep-brain stimulation delivers electrical pulses directly to brain tissue that controls movement, reducing tremors or problems of rigidity in patients with Parkinson
Putting two specific types of neural cells directly into an aging brain can kick-start creation of brain cells linked to learning and memory.
Information travels between brain cells along hairlike extensions called axons. Researchers have found that axons don't just transmit information - they can turn the signal up or down with the right stimulation.
