Researchers Find Fewer Neurons in the Amygdala of Males with Autism

...ed that the brains of males with autism have fewer neurons in the amygdala//, a part of the brain involved in...ann counted and measured representative samples of neurons in the amygdala of nine postmortem brains of males who had autism and 10 postmortem brains of males ...

Discovery of Agile Molecular Motors Could Aid in Treating Motor Neuron Diseases

...ng, walking, breathing, and swallowing. When these neurons die, the muscle itself atrophies. A well-known motor neuron disease is amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig’s disease). Using a specially-constructed microscope that allows researchers to observe the action of one macro...

Serotonin the Answer for Anti-Obesity Treatment

... in the brain, found that serotonin activates some neurons and melanocortin-4 receptors, or MC4Rs, to curb appetite and at the same time blocks other neurons that normally act to increase appetite. The dual effect helps explain how such drugs, including Fe...

Fewer Neurons in Amygdala of Autistic Males

...unication skills as well as a diminished number of neurons in their amygdala, according to the findings// of ...ifornia, Davis conducted a survey on the number of neurons in the amygdala of nine autistic males and 10 nonautistic males ranging from ages 10 to 44. Their fi...

A boon to the paralyzed -Brain Gate Neural Interface System

...sten to firing patterns of ensembles of individual neurons in the human brain for extended periods of time. We hope the knowledge gained from this work will allow the development of systems that provide improved communication and environmental control for people with paralysis and someday, when combined with...

Study Suggests Links Between Diabetes And Multiple Sclerosis

...tients with diabetes, and the myelin sheath of the neurons in those suffering from MS. Dr. Nete M. Nielsen, from the Statens Serum Institut in Copenhagen, and colleagues, evaluated the emergence of MS in 6078 patients with type-1 diabetes with more than a decade of follow-up, and observed that patients w...

Genetic Variations In Detoxifying Genes Lead To Lou Gehrig's diseases

... a complex neurodegenerative disorder of the motor neurons that results in muscle weakness, difficulty speaking, swallowing, and breathing and eventual total paralysis and death generally within five years. In 1993 Siddique and collaborators determined that mutations in a gene known as SOD1 account for 20 ...

Cancer Causing Protein May Heal Alzheimers

...lays a surprising role in restoring the ability of neurons to regenerate // , making it an important target for addressing spinal cord damage or neurological diseases like Alzheimers. "The finding suggests that the same process this protein uses for proliferating cancer could also potentially be used to reg...

Using Mobile Phones For 45 Minutes Causes Excitation In The Brain

Stem Cells Help Paralyzed Mice Walk

... stem cells with the chemicals that turn them into neurons and then transplanted them into the spinal cords of the mice. Other rats received stem cells mixed with a growth factor called GDNF, injections of chemicals or substances to boost their survival chances. Only the rats, which received all of the abov...

Sound Separated into Sound Frequencies

... sound frequencies best activate certain groups of neurons in the auditory cortex. Scientists have used electrophysiological and anatomical studies to determine which areas of the brain are responsible for certain frequencies - but mainly in animals, like those of the macaque monkey. These kinds of studies...

Brain Septum Could Help In reducing Epileptic Seizures

...s that the septum keeps the electrical activity of neurons within certain areas of the brain working within normal ranges,” Colom said. “By keeping the neurons firing normally, the septum inhibits neuronal hyperexcitability, such as epilepsy, and hypoexcitabli...

'Microscopic Grains Used in Sun Block Creams may Cause Nerve Damage'

...ures of mice cells called microglia, which protect neurons in the brain from harm. They found the particles provoke the cells to manufacture chemicals that are protective in the short term but potentially damaging when released in the prolonged manner seen in the experiments. Gunter Oberdwrster, a specia...

Smell Decoding System In Brain –Research Find

...d mice to different odors and measured response of neurons across the olfactory bulb with intrinsic signal imaging. The imaging technique maps brain activity by detecting changes in reflected light from the brain with a sensitive camera. To start, the researchers separated and identified the volatile compo...

Animal Study Found Cure For Huntington Disease
