Patients with epilepsy who underwent brain surgery soon after failing to respond to drug treatment, but who also continued to receive drug therapy, had a lower risk of seizures during the 2nd year of follow-up compared to patients who received drug treatment alone, according to a study in the March 7 issue of JAMA.

Neuroscientist group finds daydreaming uses same parts of the brain as social skills
(Medical Xpress) — A group of Australian neuroscientists have been reviewing the results of many studies done over the years regarding the parts of the brain that are thought to be used in different real world scenarios and have found that many of them appear to be involved when people go into what is called a default network – more commonly known as daydreaming, or running on auto-pilot. Their findings suggest, as they write in their paper published in Nature Reviews Neurology, that the default network is tied very closely with the same areas of the brain generally thought of as those used for social skills.
Nose spray for panic attacks?
(Medical Xpress) — Max Planck researchers have succeeded in showing in experiments on mice that the anxiolytic substance neuropeptide S (NPS) can be absorbed through the nasal mucosa and unfold its effect in the brain. Having bound to its receptors, the neuropeptide S reaches particular neurons in the brain in this way. Just four hours after the administration of the drug, the tested mice showed less anxiety. Altered neuronal activity was also measured directly in the hippocampus, an important brain structure for learning and memory. These findings confirm that neuropeptide S is a promising new drug for the treatment of patients suffering from anxiety disorders.
