The links between cardiovascular disease and cognitive impairment begin years before the appearance of the first clinical symptoms of either condition. In a study carried out at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) in partnership with Santander Bank and neuroimaging experts at the Barcelonaβeta Brain Research Center (BBRC, the research center of the Fundación Pasqual Maragall), the investigators have identified a link between brain metabolism, cardiovascular risk, and atherosclerosis during middle age, years before the first appearance of symptoms.
The Neurology Behind Bad Food Experiences by Anjanee Sharma on February 14, 2021 at 4:25 PM
Researchers from Sussex, UK, believe that bad food experiences might be leading to a switch in our brain, thereby impacting our future eating habits. Using sugar-loving snails as models, They found this by using snails that love sugar as their models.
It is widely common that a negative experience with food usually leads to reluctance in eating that particular food again.
Snails like sugar and start feeding on it as soon as it is presented to them. Researchers altered this behavior using aversive training by tapping the snails gently on the head when sugar appeared. Due to this, the snails then refused to feed on the sugar, even when they were hungry.
Researchers investigate which stress tests trigger similar brain activation patterns
Scientists use many different tests to investigate what happens in the brain in people experiencing stress. It is unclear to what extent the various methods with which subjects are placed under stress are comparable to each other. In a meta-analysis, a biopsychology team from Ruhr-Universität Bochum compared 31 previous studies that had investigated stress using functional magnetic resonance imaging (fMRI).
The team worked out which regions of the brain are activated as standard during stress and which stress tests trigger similar activation patterns. They describe the results in the journal

Born and raised in Russia, in 2003 I graduated with Diploma (biology and chemistry teacher) from the Ulyanovsk Pedagogical University. During my undergraduate (1998-2003) and later MSc studies (2003-2005) at the Saint Petersburg State University, Russia, I was contributing to several research projects in the field of avian movement ecology and bird navigation under the supervision of the academic staff of the Biological station Rybachy with which I still collaborate. This research institution is remarkable for being the descendant of the world s first bird observatory Vogelwarte Rossitten (German: Bird Observatory Rossitten ) established in 1901 on the southeastern coast of the Baltic Sea - a hot spot for bird migration in Europe. Now it is a branch of the Zoological Institute of Russian Academy of Sciences and one of the leading centres studying bir
Does everyone see the same colour when they see red?
Neuroscientists tackling the age-old question are coming up with some interesting answers.
Is the red I see the same as the red you see?
At first, the question seems confusing. Colour is an inherent part of visual experience, as fundamental as gravity. So how could anyone see colour differently than you do?
To dispense with the seemingly silly question, you can point to different objects and ask, “What colour is that?” The initial consensus apparently settles the issue.
You are confronted with an unsettling possibility. Even if we agree on the label, maybe your experience of red is different from mine and – shudder – could it correspond to my experience of green? How would we know?
