Weekly Neuroscience Update

Melatonin is a hormone known to promote sleep, but its underlying mechanisms are unknown. Now, researchers have discovered how melatonin suppresses neurons in the brain that keeps you awake and alert. These findings could lead to new therapies for those who suffer from insomnia.

A new study shows how specific neurons can process sensory information about temperature and facilitate a change in behavior to adapt to the climate.

Researchers have identified electrical activity in the brain that is specific to the start of migraines. The new study reports spreading depolarization can be seen as a migraine begins, and an electrical current can be used to stop it in its tracks.

Adolescent drinking is associated with changes in the metabolite profile, a new study shows. 

Scientists are using big data and artificial intelligence to map neural networks in the brain. The new technology could help to better understand the progression of neurodegenerative diseases.

Sound and object motion can be used to change perceptions about body size, according to a new study.

Researchers report impairments in the neuroprotective communication between neural blood vessels, astrocytes and neurons may be an early factor in how high blood pressure may impair cognitive function.

A new study confirms a link between a number of autoimmune diseases and an increased risk of developing psychosis.

Autonomous Sensory Meridian Response (ASMR) – the relaxing ‘brain tingles’ experienced by some people in response to specific triggers, such as whispering, tapping and slow hand movements – may have benefits for both mental and physical health, according to new research.

Researchers have developed new neural implants that enable targeted delivery of drugs deep into brain structures.

A new study reports specific alterations in signaling circuits associated with memory can induce an abnormal response in neurons, which is linked to the aging process and cognitive decline.

Researchers say the combination of low muscle mass and strength in the context of high-fat mass, could be a predictor of cognitive function in older adults. 

Obstructive sleep apnoea (OSA) is associated with changes to the structure of the brain that are also seen in the early stages of dementia, according to a study published in the European Respiratory Journal.

Finally, this week, a new study reports a mother’s diet during pregnancy may have an effect on the composition of her child’s gut bacteria.

Researchers report the brain’s reward network could play an influential role in evaluating the opportunity to gain new information, just as it does to evaluate rewards such as food or financial gain.

Scientists are beginning to understand the neuroscience behind sensory processing disorder and are developing new therapies to help those with it.

A new study shows Alzheimer’s disease does not appear to affect the salience network. Researchers found, when listening to music, the salience network along with other networks, show higher functional connectivity in Alzheimer’s patients.

A new study reveals maternal diet during pregnancy can have implications for fetal brain development and can impact short-term memory in adults.

Scientists have uncovered dozens of genes that increase the risk of depression — a major finding that underscores the complexity of the disease and reveals why antidepressant therapies work well for some people but are utterly ineffective for others.

Researchers report the critical period of language learning may be longer than previously believed. A new study reveals children remain skilled at learning new languages until age 18.

Treatment for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population, according to a radical new model of emotion in the brain.

Finally this week, researchers report high sugar and fat based diets that lead to obesity, coupled with the normal aging process, may increase the risk of Alzheimer’s disease.

A new study sheds light on how the brain helps us to learn and make decisions in the real world.

Scientists have shown for the first time that non-invasive brain stimulation can be used like a scalpel, rather than like a hammer, to cause a specific improvement in precise memory.

Neurons in the subiculum appear to encode the current axis of travel, a new study reports.

A new study has shown for the first time that cognitive behaviour therapy (CBT) strengthens specific connections in the brains of people with psychosis, and that these stronger connections are associated with long-term reduction in symptoms and recovery eight years later.

Researchers have discovered a mechanism the brain uses to help compensate when noise obscures speech sounds.

An international team of researchers has found evidence that the specific type of protein clumps in a person’s brain might help identify different ‘types’ of Alzheimer’s disease.

A new technology that allows researchers to examine circulation in the brain could help to identify early signs of neurological problems.

A group of neurons in the forebrain release dopamine when activated by visual or tactile stimuli, a new study reports.

Finally this week, researchers report using neuroimaging to map the brains of preterm babies soon after their born could hold clues as to possible disabilities they may develop.

Granule cells connect with other cells via long projections (dendrites). The actual junctions (synapses) are located on thorn-like protuberances called “spines”. Spines are shown in green in the computer reconstruction Credit DZNE/Michaela Müller.

New findings on the link between nerve cells at the interface to the hippocampus may have an influence on learning and memory.

People choosing between two or more equally positive outcomes experience paradoxical feelings of pleasure and anxiety, feelings associated with activity in different regions of the brain, according to research at the Princeton Neuroscience Institute at Princeton University.

Latest findings on how stress hormones promote the brain’s building of negative memories.

Researchers have studied the changes in the brain that are associated with impulsiveness, a personality trait that causes difficulties in inhibiting a response in the face of a stimulus and leads to unplanned actions without considering the negative consequences. These patterns can serve as an indicator for predicting the risk of behavioural problems.

People taking dopamine for Parkinson’s disease sometimes begin to generate a lot of artwork. New research differentiates their expressiveness from obsessive or impulsive tendencies.

Researchers have uncovered more than 100 genetic markers linked to developing schizophrenia.

A type of immune cell widely believed to exacerbate chronic adult brain diseases, such as Alzheimer’s disease and multiple sclerosis (MS), can actually protect the brain from traumatic brain injury (TBI) and may slow the progression of neurodegenerative diseases, according to research published in the online journal Nature Communications.
