New study shows that uneven accumulation of amyloid β is linked to olfactory dysfunction or partial loss of smell, an early symptom of Alzheimer’s disease

Researchers from the University of Tsukuba have discovered a group of neurons in the mouse brainstem that control muscle tone. Inhibiting these neuronal cells caused mice to move during REM sleep, reminiscent of REM sleep behavior disorders. These neurons were also responsible for episodes of cataplexy in a mouse model of narcolepsy; inhibiting them reduced the number of cataplexic bouts. These circuits could thus be a new target for treating these sleep disorders.

A new mechanism of action by which misfolded proteins cause indirect damage to neurons

DGIST scientists are learning more about the molecular processes involved in the formation of well-communicating nerve fibres.

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, show that it is possible to distinguish between left-handed and right-handed people by noninvasively monitoring just their brain activity during passive tactile stimulation. These results are key in haptic research (the study of sensory systems) and have various important implications for brain–computer interfaces, augmented reality, and even artificial intelligence.

Running is a fundamental mode of human movement that most of us perform effortlessly without conscious thought. Some may run regularly for exercise, or even undergo serious, professional training for completing marathons. This apparent ease of running belies the enormous biomechanical complexity of running, the coordinated control of which is accomplished by an intricate neuronal network in the brain and spinal cord.

Researchers at the University of Tsukuba and RIKEN in Japan spark a hibernation-like state in mice—a species that does not naturally hibernate

Researchers from University of Tsukuba and the University of Tokyo identify neurons responsible for memory consolidation during REM sleep

An implantable device has the potential to revolutionize how neuroscientists study the brain and treat diseases.

New findings could lead the way towards treatments for intellectual disability in Down syndrome.

Over 70% of rare disease patients and non-patients are aware of the patient registry but the participation rate accounted for less than 30%, according to a recent survey of the public’s acknowledgement of and participation in the rare disease patient registry.

The mistletoe fig reduces toxic oxidative stress in diabetic rat brains, while also keeping the cortex wrinkly and improving cognition.
