GABA Disinhibition Shows Promise For Depression Treatment

Drugs that target the neurotransmitter GABA could serve as rapidly acting and more effective antidepressants, suggest new tests in mice. Research team leader Bernhard Lüscher, professor of biology and of biochemistry and molecular biology at Penn State, said: “GABA is the major inhibitory neurotransmitter in the brain—it acts as the…Continue readingGABA Disinhibition Shows Promise For Depression Treatment

The Neural Switch That Turns Dreams Off And On

At the flip of a switch, University of California, Berkeley, neuroscientists can send a sleeping mouse into dreamland. The researchers inserted an optogenetic switch into a group of nerve cells located in the ancient part of the brain called the medulla, allowing them to activate or inactivate the neurons with…Continue readingThe Neural Switch That Turns Dreams Off And On

Brain Structure Generates Pockets Of Sleep Within The Brain

Sleep is usually considered an all-or-nothing state: The brain is either entirely awake or entirely asleep. However, MIT neuroscientists have discovered a brain circuit that can trigger small regions of the brain to fall asleep or become less alert, while the rest of the brain remains awake. This circuit originates…Continue readingBrain Structure Generates Pockets Of Sleep Within The Brain

Brain Chemical Aids Tic Control In Tourette Syndrome

A chemical in the brain could potentially be harnessed to help young people with Tourette Syndrome (TS) to overcome the physical and vocal tics associated with the neurological disorder, say researchers. Academics from The University of Nottingham reviewed recent evidence that the neurochemical known as Gamma Aminobutyric acid (GABA) is…Continue readingBrain Chemical Aids Tic Control In Tourette Syndrome

Oxytocin And Alcohol Have Similar Behavioural Effects

Oxytocin is a neuropeptide hormone produced in the hypothalamus and secreted by the posterior pituitary gland. It has long been established as playing a significant role in childbirth and maternal bonding. More recently it has been identified as a brain chemical with a key role in determining our social interactions…Continue readingOxytocin And Alcohol Have Similar Behavioural Effects

Brain Chemical Possible New Hope For Control Of Tourette Syndrome Tics

A chemical in the brain has a key role in controlling the involuntary movements and vocal tics seen in Tourette Syndrome (TS), a new study has shown. The research, from psychologists at The University of Nottingham, could offer a potential new target for the development of more effective treatments to…Continue readingBrain Chemical Possible New Hope For Control Of Tourette Syndrome Tics
