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 cerebral cortex is a limited resource. Evolution has employed some impressive tricks to increase the amount of cortex available, such as folding it, therefore getting more surface in the same volume, or putting different things in the left and right hemisphere instead of duplicating them, thus enlarging its capacity to accommodate specific functions such […]

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 […]

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 […]

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) includes sensory alterations as one of the four characteristics of restricted / repetitive behavior of people with autism spectrum disorder (ASD). It defines this symptom characteristic as a «hyper- or hyporeactivity to sensory inputs or an unusual interest for sensory aspects of the environment» […]

In 1873, the microscopist Ernst Abbe stipulated a physical limit for the maximum resolution of traditional optical microscopy: 0.2 micrometers, or 200 nanometers (the shortest wavelength for visible light, the extreme limit of violet). This meant that scientists could distinguish whole cells, as well as some parts of the cell called organelles. However, they would […]
