Study identifies brain regions that appear to play key role in supporting fluid intelligence

People with specific brain attributes are more likely than others to benefit from targeted cognitive interventions designed to enhance fluid intelligence, scientists report in a new study. Fluid intelligence is a measure of one's ability to adapt to new situations and solve never-before-seen problems.

Respiration key to oxygenation in the brain

Contrary to accepted knowledge, blood can bring more oxygen to mice brains when they exercise because the increased respiration packs more oxygen into the hemoglobin, according to an international team of researchers who believe that this holds true for all mammals.

Researchers identify brain networks that play key role in suicide risk

An international team of researchers has identified key networks within the brain they say interact to increase the risk that an individual will think about - or attempt - suicide.

Understanding brain areas responsible for perception of touch

An encouraging pat on the back or a soft sweater on the skin - even things that we do not actively explore with the hands, we perceive with our body perception. "Which brain areas are responsible for this perception of touch, however, is still largely unknown," says Privatdozent Dr. Burkhard Pleger, neurologist at the Berufsgenossenschaftlichen Kliniken Bergmannsheil in Bochum and co-author of the study.

Dreams can help us react better to frightening situations

Do bad dreams serve a real purpose? To answer this question, researchers from the University of Geneva and University Hospitals of Geneva, Switzerland, - working in collaboration with the University of Wisconsin (USA) - analyzed the dreams of a number of people and identified which areas of the brain were activated when they experienced fear in their dreams.

Meta-analysis reveals brain areas involved in decision-making for social punishment

Oksana Zinchenko, Research Fellow at the Institute of Cognitive Neuroscience, HSE University, has conducted meta-analysis of 17 articles to find out which areas of the brain are involved decision-making for rendering social punishment.

Transplanted human brain cells in a mouse brain provide insight into neural circuit formation

The brain cortex, the outside layer of our brain often referred to as grey matter, is one of the most complex structures found in living organisms. It gives us the advanced cognitive abilities that distinguish us from other animals.

Exploring the links between chronic stress, inflammation and depression

Chronic stress can inflame our brain, destroy the connections between our neurons and result in depression, scientists say.

Study of 'face blindness' provides clues to what goes wrong in the brain

People with prosopagnosia, or "face blindness," have trouble recognizing faces -- even those of close friends and family members.

Study shows how a potent psychedelic changes our waking brain waves

Scientists have peered inside the brain to show how taking DMT affects human consciousness by significantly altering the brain's electrical activity.

Study offers significant contribution for recovery of motor functions

Delivering a diversified electric message to the different fibres of the injured spinal cord through a new technology able to deliver it in a targeted and independent manner. What is the result? Greater efficiency in recovering the control of voluntary limb movements in the event of serious damage to the spinal cord.

Certain brain regions must be intact in stroke survivors with aphasia for successful speech entrainment

In an article in Brain, researchers at the Medical University of South Carolina (MUSC) and elsewhere report which brain regions must be intact in stroke survivors with aphasia if they are to perform well in a speech entrainment session, successfully following along with another speaker.

Hiccups in a newborn could mean their brains are developing say researchers

Newborn babies seem to hiccup a lot and there are myths and legends surrounding such behaviour. Now researchers have found that with each such hiccup in a new born, there is a trigger of brain signals that help the baby’s brain figure out breathing. The UCL scientists published the findings of their study in the latest issue of the journal Clinical Neurophysiology.

White noise background improves hearing, study shows

Noise is not the same as noise - and even a quiet environment does not have the same effect as white noise.

Understanding neural processes behind motor behaviours and learning

Researchers have provided new insight into the neural processes behind movement and learning behaviours, according to a study published today in eLife.

Study may shake up certain conventional theories on workings of sense of smell

Is a pair of brain structures called the olfactory bulbs, which are said to encode our sense of smell, necessary? That is, are they essential to the existence of this sense? Weizmann Institute of Science researchers recently showed that some humans can smell just fine, thank you, without olfactory bulbs.

Study explains the origin of brain mapping diversity for ocular dominance

The human visual brain devotes most of its neuronal resources to process the part of the visual scene that we see with both eyes.

Study sheds new light on the brain's spatial map

An important aspect of human memory is our ability to conjure specific moments from the vast array of experiences that have occurred in any given setting. For example, if asked to recommend a tourist itinerary for a city you have visited many times, your brain somehow enables you to selectively recall and distinguish specific memories from your different trips to provide an answer.
