Zebrafish have become the animal model of choice for research in many areas. Now, researchers from Rice University trace roots of cancer development using genetically modified zebrafish. These fish produce fluorescent tags in migratory embryonic nerve precursor cells, enabling them to trace neuroblastoma and other forms of cancer.
Researchers from Arizona State University and the Icahn School of Medicine at Mount Sinai Indiana University made a large-scale analysis and used data from three different brain banks. They concluded that human herpes viruses are more abundant in the brains of Alzheimer’s patients and may play a role in regulatory genetic networks believed to be behind the onset of the disease. New possibilities for Alzheimer’s treatment, such as antiviral and immune therapy, are now open.
Researchers from UCLA successfully transplanted memories by transferring RNA from one sea snail into another. They are one step closer to solving the puzzle of the physical basis of memory. In the long run, these findings could lead to treatments of diseases such as Alzheimer’s or post-traumatic stress disorder (PTSD).
Researchers decoded specific signals the nervous system uses to communicate the body’s immune and inflammatory status to the brain. Understanding the “language” of the brain is a major step forward for bioelectronic medicine as it provides insight into diagnostic and therapeutic targets. The team hopes that future bioelectronic devices could replace drugs and reduce hamrful side effects.
An international clinical study demonstrated astounding recovery of patients with multiple sclerosis after a stem cell transplant. Scientists claim these transplants are dramatically better than standard drugs at halting the spread of multiple sclerosis and improving its symptoms.
New research reveals genetic mysteries behind synesthesia – a condition in which different senses seem to be crossed up in the brain, causing a person to “taste” words or even “feel” numbers. The phenomenon has been intriguing neuroscientists for years and this research could unlock new doors to understanding how our brains process sensory input.
US military financed research groups are finding new ways of treating severe mental illnesses that resist current therapies. They have developed a new single closed-loop system to detect patterns associated with mood disorders and presented the first map of how mood is encoded inside the brain.
Scientists from Stanford discovered that oxytocin is crucial for newly described brain circuitry involved in social interactions. The finding may offer clues to unlock treatment for social aversion, which could help people with depression, schizophrenia, and autism.
Consciousness has been defined as awareness, a person’s ability to experience and feel, an enigma that defies explanation. The nature of consciousness intrigued philosophers and psychologists for thousands of years. Modern neuroscience is giving some answers that could lighten the physical source of our consciousness and some promising fundamental theories are being established.
European researchers demonstrated that a low dose of delta-9-tetrahydrocannabinol (THC), the main active substance of cannabis, profoundly reduced age-related cognitive impairment in mice. The drug increased behavioural performance and rejuvenated the elderly brain, closely resembling that of young, untreated animals.
