Hereditary trauma: Inheritance of traumas and how they may be mediated

Extreme and traumatic events can change a person — and often, years later, even affect their children. Researchers of the University of Zurich and ETH Zurich have now unmasked a piece in the puzzle of how the inheritance of traumas may be mediated. The phenomenon has long been known in psychology: traumatic experiences can induce behavioural disorders that are passed down from one generation to the next Continue reading

Brain cell discovery could open doors to targeted cancer therapies

Brain cell discovery could open doors to targeted cancer therapies

Fresh insights into the processes that control brain cell production could pave the way for treatments for brain cancer and other brain-related disorders. Scientists have gained new understanding of the role played by a key molecule that controls how and when nerve and brain cells are formed — a process that allows the brain to develop and keeps it healthy Continue reading

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

The unconscious process by which human beings perceive the position of their body parts — known as proprioception — is a critical element of the body’s motor control system. Proprioceptive feedback plays a key role in rehabilitation following a brain injury. Continue reading

Online registry to drive brain disease research

Online registry to drive brain disease research

A new online project led by researchers at UC San Francisco promises to dramatically cut the time and cost of conducting clinical trials for brain diseases, while also helping scientists analyze and track the brain functions of thousands of volunteers over time. With easy online registration, the Brain Health Registry is designed to create a ready pool of research subjects for studies on neurological diseases, such as Alzheimer’s and Parkinson’s, as well as depression, post-traumatic stress disorder and many other brain ailments.

DNA modifications measured in blood signal related changes in the brain

DNA modifications measured in blood signal related changes in the brain

Johns Hopkins researchers say they have confirmed suspicions that DNA modifications found in the blood of mice exposed to high levels of stress hormone — and showing signs of anxiety — are directly related to changes found in their brain tissues. The proof-of-concept study, reported online ahead of print in the June issue of Psychoneuroendocrinology , offers what the research team calls the first evidence that epigenetic changes that alter the way genes function without changing their underlying DNA sequence — and are detectable in blood — mirror alterations in brain tissue linked to underlying psychiatric diseases. The new study reports only on so-called epigenetic changes to a single stress response gene called FKBP5, which has been implicated in depression, bipolar disorder and post-traumatic stress disorder Continue reading

Patients with paraplegia regain voluntary movement after spinal stimulation

Patients with paraplegia regain voluntary movement after spinal stimulation

Four people with paraplegia are able to voluntarily move previously paralyzed muscles as a result of a novel therapy that involves electrical stimulation of the spinal cord, according to a study funded in part by the National Institutes of Health and the Christopher & Dana Reeve Foundation.

Renal cancer cells thrive when put in right environment, supported by specific enzyme

Renal cancer cells thrive when put in right environment, supported by specific enzyme

Tumor cells are picky about where they live. In the wrong environment, they fail to reach their potential. Continue reading

Light-activated neurons from stem cells restore function to paralyzed muscles

Light-activated neurons from stem cells restore function to paralyzed muscles

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches Continue reading
