Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.

Researchers reveal the path of information received by the hippocampus. Using optogenetics during large-scale recordings of rat subiculum, they discovered that the subiculum distributes information from the hippocampus to 4 downstream regions of the brain. They observed that the theta and sharp-wave/ripples in the subiculum controlled information transmission with millisecond precision according to the target region. This provides the foundation for a comprehensive understanding of the hippocampal memory system.

Spinocerebellar ataxia type 3 (SCA3), also known as Machado-Joseph Disease (MJD), describes the most common form of dominantly inherited ataxia in many populations worldwide, including Hong Kong and mainland China. SCA3 or MJD patients often present problems with gait and balance, blurred vision, and speech difficulties. The symptoms are progressive, and patients may eventually decline into a bed-ridden state. To date, SCA3 or MJD remains an incurable disorder. Collaborating with the University of Oxford, Professor Ho Yin Edwin Chan’s research team from the School of Life Sciences of The Chinese University of Hong Kong (CUHK) recently unveiled the counteracting relationship between pre-mRNA-processing factor 19 (Prpf19) and exocyst complex component 7 (Exoc7) in controlling the degradation of disease protein and neurodegeneration of the rare hereditary ataxia. The research findings have been published in the prestigious scientific journal, Cell Death & 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.

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.

The Neuroscience Research Group is a multi-disciplinary team investigating the nervous system. They are focusing on animal behavioral models for memory in the laboratory. They are studying the effects of food, such as Habbatus Sauda/Black cumin (Nigella sativa) and honey, on brain microstructures and memory. They also compare Islamic and neuroscience perspectives on issues like learning and sleep for children with and without autism spectrum disorders.
