“The b rain 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 […]
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 […]
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 […]
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 […]
Cortical neurons often fire together as a group, rather than independently, and these coactive groups, also known as neuronal ensembles (or chains, assemblies, attractors, clicks, motifs, songs, bumps, etc.), could constitute emergent functional units of the brain, as modular building blocks of memories, thoughts, motor programs, computations, or perceptual or mental states. In order to […]
As one of those people who REALLY love to sleep -and doesn’t get close to enough of it- I am always interested to read on the topic. What I didn’t expect was to read about sleeping fish and how that relates to its origin . But let’s get down to the details, because if the […]
The cicadas are part of the soundtrack of summer. Their calls, especially if a large number of animals is gathered, can form an impressive concert. They are part of the hemiptera, the order of aphids and bedbugs, but they do not have the bad reputation of these others, although they are not beneficial either. The […]
Autism spectrum disorders (ASD) have among their diagnostic characteristics problems for communication and social interaction. The typical example is the difficulty to understand the facial expressions or the body language of other people, but in addition to these aspects mediated by the visual system there may be other senses affected and, in fact, it has […]
A preterm baby is one that is born prematurely, a minimum of three weeks before the expected date of delivery or, in other words, before the 37th week of pregnancy. Premature babies, especially extreme premature babies, have a high risk of suffering from nervous system problems, especially cerebral palsy, neurodevelopmental delays, and hearing and vision […]
