For the greatest chance of survival, cancer screening needs to detect the disease before symptoms appear. Current cancer detection involves blood tests, urine tests, DNA tests, and/or medical imaging, however, … Continue Reading DNA computer can detect cancer on a single-cell basis.
In his famous experiment, Ivan Pavlov rang a bell each time he fed his dogs, which resulted in the animals drooling in anticipation every time they heard the bell, even … Continue Reading Study identifies the brain cells regulating the Pavlovian response.
Diseases related to tobacco smoking have been shown to kill approximately half of long-term smokers when compared to average mortality rates faced by non-smokers. Giving up smoking has huge benefits … Continue Reading Brain circuit that supports smoking cessation identified.
Genetically-coded brain circuits can switch feeding and drinking behaviours on and off in mice.
Various neuronal activity recording and stimulating devices enable cellular exploration to further understand AI, brain diseases, and work towards developing the ‘immortal download’. Brain functions are controlled by millions of … Continue Reading A small step towards the immortal download, new neurochip records long-term brain cell activity.
The decision to engage in food-seeking behaviour depends on homeostatic signals relating to energy balance and the presence of competing motivational drives, as well as learned brain cues signaling food … Continue Reading Neuroimaging shows the effect of hunger on the brain’s response to food cues.
The molecular intricacies of hunger and satiety, pivotal for understanding metabolic disorders and the problem of obesity, are not yet fully understood by scientists. How much a person eats and … Continue Reading Protein responsible for regulating feeding behaviour in the brain identified.
The immune system exercises constant vigilance to protect the body from external threats, including what the person eats and drinks. A careful balancing act plays out as digested food travels … Continue Reading Study finds neurons in gut regulate the immune system to control inflammation.
Homeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. The human body manages a multitude of highly complex … Continue Reading Neuroimaging identifies previously unknown circuitry in brain homeostasis.
Internet gaming disorder (IGD) is defined as a failure to control one’s impulses to excessively use online gaming. IGD results in serious negative outcomes, such as decreased physical and mental … Continue Reading Neuroimaging identifies brain differences in compulsive video game players.
Currently, more than 6 million children in the United States, or 11% of all children aged 4 to 17, have received attention-deficit hyperactivity disorder (ADHD) diagnoses. The disorder is characterized … Continue Reading Neuroimaging shows interactions in attention-based brain networks weaker in children with ADHD.
Cocaine is a strong central nervous system stimulant that increases levels of the neurotransmitter dopamine in brain circuits regulating pleasure and movement. Normally, dopamine is released by neurons in these … Continue Reading Researchers begin to map brain regions and circuits changed by cocaine-use.
Obesity is a significant risk factor for cardiovascular disease, diabetes, and cancer. Although obesity can stem from behavioural factors such as diet and physical inactivity, central nervous system changes can … Continue Reading Neuroimaging maps areas of the brain in obese children activated by food odours.
Scientists at The Scripps Research Institute (TSRI) have discovered that a brain protein has a key role in controlling binge drinking in animal models. They found that deleting the gene … Continue Reading Researchers identify brain protein responsible for controlling binge- drinking.
Researchers at the Max Planck Institute, VU University Amsterdam and Max Planck Florida Institute state that they have succeeded in reconstructing the neuronal networks that interconnect the elementary units of … Continue Reading New 3d neuronal labeling technique provides most comprehensive study of cortical circuitry to date.
The brain function of people addicted to cocaine is different from that of people who are not addicted and often linked to highly impulsive behavior, according to a new study … Continue Reading Neuroimaging study finds functional differences in brain communication in cocaine users.
