Brain power: Wirelessly supplying power to the brain

by Dr. Jekyll in Lunatic Laboratories

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

Why Ask for Directions? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

by Anna Schneider For the iconic monarch butterfly, the shorter days in fall mean it’s time to pack up and head south to a warmer climate! Just like clockwork, the Eastern population of monarch butterflies makes a 2000 mile journey to their winter paradise roosts in central Mexico. The journey in itself is one of the greatest migrations among all animals. But here’s the catch: none of these butterflies has made this trip before. Several generations of monarchs have come and gon........ Read more »

The molecular link between psychiatric disorders and type 2 diabetes

by Dr. Jekyll in Lunatic Laboratories

There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Brain plasticity assorted into functional networks

by Dr. Jekyll in Lunatic Laboratories

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

Do songbirds perceive melody different from humans?

by Henkjan Honing in Music Matters

Last week a fascinating study appeared in PNAS on melody cognition in sparrows (Sturnus vulgaris). It provides an alternative interpretation to the widespread believe that songbirds have a strong bias to rely on absolute pitch (AP) for the recognition of melodies (e.g. Hulse et al., 1992)....

Man-made underwater sound may have wider ecosystem effects

by Dr. Jekyll in Lunatic Laboratories

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

A sense of mystery results from the brain failing to shut down flights of fancy

by Tom Rees in Epiphenom

People who have a mystical experience might describe it as being “touched by some higher or greater truth or power“, or as “experiences felt or experienced beyond the realms of ordinary consciousness”. Psychologists define them as a breakdown in the usual sense of time or space, or of the difference between the self and the [Read More...]... Read more »

Investigating potential fetal exposure to antidepressants

by Dr. Jekyll in Lunatic Laboratories

Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.

Depressed or inflamed? Inflammation attacks brain’s reward center

by Dr. Jekyll in Lunatic Laboratories

Inflammation is a good thing, it helps the body fight disease, and without it we wouldn't survive. Unfortunately, when inflammation isn't kept under control it can wreak havoc on the body. From potentially causing alzheimer's to arthritis it seems that unchecked inflammation can cause all sorts of issues. In fact, a new study adds to the list of issues out of control inflammation causes in the body.

Schizophrenia, Hubris and Science

by Neuroskeptic in Neuroskeptic_Discover





A press-release from the Harvard-MIT Broad Institute reaches astonishing heights of hyperbole in announcing a new schizophrenia study (Sekar et al. 2016). Here's the release:
Genetic study provides first-ever insight into biological origin of schizophrenia

Landmark analysis reveals excessive "pruning" of connections between neurons in brain predisposes to schizophrenia

Blood pressure medicine may improve conversational skills of individuals with autism

by Dr. Jekyll in Lunatic Laboratories

An estimated 1 in 68 children in the United States has autism. The neurodevelopmental disorder, which impairs communication and social interaction skills, can be treated with medications and behavioral therapies, though there is no cure. Now, University of Missouri researchers have found that a medication commonly used to treat high blood pressure and irregular heartbeats may have the potential to improve some social functions of individuals with autism.

The brains of patients with schizophrenia vary depending on the type of schizophrenia

by Dr. Jekyll in Lunatic Laboratories

I have a friend who lost an eye to his brother. Yes, you read that correctly, his brother tried to kill him and in the process he lost his eye. I’ve told this story before, but whenever new schizophrenia research comes out I feel the need to tell it again. While he has forgiven his brother (partly because not long after, he was diagnosed as schizophrenic), he will not be able to see him again until he is released from prison. A tragedy that could’ve been avoided had he been diagnosed sooner......... Read more »

Coal tar, dyes, and the unlikely origins of psychotherapeutic drugs

by neurosci in Neuroscientifically Challenged










While it may be difficult to imagine in a day and age when psychiatric medicines are advertised as a way to treat nearly every mental disorder, only 65 years ago targeted and effective psychiatric medicines were still just an unrealized aspiration. In fact, until the middle of the 20th century, the efficacy and safety of many common approaches to treating mental illness were highly questionable. For example, one method of treating schizophrenia that was common in the 1940s........ Read more »

Neurological adaptations to the presence of toxic HIV protein

by Dr. Jekyll in Lunatic Laboratories

Nearly half of HIV infected patients suffer from impaired neurocognitive function. The HIV protein transactivator of transcription (Tat) is an important contributor to HIV neuropathogenesis because it is a potent neurotoxin that continues to be produced despite treatment with antiretroviral therapy.

The Automatic Neuroscientist

by Neuroskeptic in Neuroskeptic_Discover

We've learned this week that computers can play Go. But at least there's one human activity they will never master: neuroscience. A computer will never be a neuroscientist. Except... hang on. A new paper just out in Neuroimage describes something called The Automatic Neuroscientist. Oh.



So what is this new neuro-robot? According to its inventors, Romy Lorenz and colleagues of Imperial College London, it's a framework for using "real-time fMRI in combination with modern machine-learning te... Read more »

It’s complicated: Benefits and toxicity of anti-prion antibodies in the brain

by Dr. Jekyll in Lunatic Laboratories

Immunotherapy to ameliorate neurodegeneration by targeting brain protein aggregates with antibodies is an area of intense investigation. A new study examines seemingly contradictory earlier results of targeting the prion protein and proposes a cautionary way forward to further test related therapeutic approaches.
