Living with half a brain

Living with half a brain

Neurobiology

By José Ramón Alonso

Many people think of their brain as a computer full of microchips and wires, as a storehouse full of memories and learned things, as a clock with millions of mechanisms intimately intertwined with each other, so it is incredible to think that someone can live with much less than that, with only one brain hemisphere […]

Habituation and autism

Habituation and autism

Neurobiology

By José Ramón Alonso

Some people with autism do not get used to certain stimuli as normotypical people seem to do without problem. This would fit in with what in neuroscience, particularly in learning and memory issues, is called habituation. Habituation is a process by which, when faced with a repeated stimulus, the response is less and less intense […]

For a long time Alzheimer disease has been studied mostly as a neuronal disease. However, recently the role of the immune system is getting more attention and its involvement more clear. Recent research has shown that a subpopulation of T cells could be key to early Alzheimer’s detection. How were these T cells discovered? Firstly […]

NeurobiologyPsychology

The relationship between siblings is, for most people, the longest they will ever enjoy. It is fundamental for many of us, but especially for children, who live together regularly with their brother or sister, and where the fraternal relationship is part of daily life, of play and leisure, of learning basic skills, of emotional development […]

Families with members with autism spectrum disorders (ASD) are easy prey for scam artists who offer them magical solutions and therapies not backed by science. Many of these pseudotherapies are included in the so-called alternative medicine, a misnomer because they are not medical treatments and do not meet the same criteria required of a medicine: […]

“The brain is considered an isolated tissue from the rest of the body thanks to the blood-brain-barrier, which separates it at cellular level with a very strict control”. That was supposed in the past, at least until now… In 2019 a striking discovery led by the researcher Moreno-Jimenez demonstrated human neurogenesis is abundant and persists […]

Nature versus nurture: how modern science is rewriting it

EvolutionGeneticsNeurobiology

By Invited Researcher

The question of whether it is genes or environment that largely shapes human behaviour has been debated for centuries. During the second half of the 20th century, there were two camps of scientists – each believing that nature or nurture, respectively, was exclusively at play. This view is becoming increasingly rare, as research is demonstrating […]

Recognition of emotions by people with autism

Recognition of emotions by people with autism

Neurobiology

By José Ramón Alonso

Emotion recognition is the process of identifying human emotions. This is something that humans do automatically but computational methodologies have also been developed. Humans show universal consistency in recognizing emotions but also show a great deal of variability between individuals in their abilities. Whether persons with autism are able to recognize human emotions as well […]

EthologyNeurobiology

By José Ramón Alonso

Ladybugs are beautiful beetles and many present what is called an aposematic coloration, bright and striking colors that warn: do not eat me, I am dangerous. When they are disturbed, they defend themselves with legs and jaws, expel a poison and their brightly colored elytra with black dots are a warning to anyone who tries […]

Forming large groups (flocks, banks, swarms, herds, schools, …) is characteristic of many species. The generally accepted idea is that it is an adaptive process, in which the individual improves its chances of survival by being part of a numerous group. A shark does not know which fish to attack in a sardine bank and […]
