Optogenetic Research Shows Which Neurons Flip Fertility Master Switch

New Zealand scientists have achieved another milestone in their world-leading efforts to understand the neural mechanisms underlying the brain’s master control of fertility. Researchers at the University of Otago Centre for Neuroendocrinology have published the first direct evidence that it is kisspeptin neurons working in synchrony that generate the small, episodic hormone pulses that are […]

Cryo-electron Microscopy Structure Of The Slo2.2 Neural Ion Channel

Within the brain, some neurons fire off hundreds of signals per second, and after ramping up for such a barrage, they need to relax and reset. A particular type of ion channel helps bring them down, ensuring these cells don’t get overstimulated—a state that potentially can lead to severe epileptic seizures, among other problems. New […]

Why Glutamate Is An Essential Food For The Brain

Glutamate is an amino acid with very different functions. In the pancreas, it modulates the activity of the pancreatic ß-cells responsible for insulin production, whereas in the brain it is the main excitatory neurotransmitter. In recent years, it has been suspected to play an additional role in the functioning of the brain. By discovering how […]

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 responsible for dampening down the […]

High-fructose Diet Slows Recovery From Brain Injury

A diet high in processed fructose sabotages rat brains’ ability to heal after head trauma, UCLA neuroscientists report. Revealing a link between nutrition and brain health, the finding offers implications for the 5.3 million Americans living with a traumatic brain injury (TBI). According to the Centers for Disease Control and Prevention, an estimated 1.7 million […]
