Nowadays we are more aware than ever about the relevance of eating a balanced and assorted diet. However, in the more industrialized countries obesity has become almost epidemic, and it is a condition that lies at the base of many different health issues, being the cardiovascular complications probably the most obvious. But also immunological and […]

As the Hungarian mathematician Alfréd Rényi famously put it (although usually misattributed to Paul Erdös), mathematicians are devices for turning coffee into theorems. Other people drink coffee for a variety of reasons, and considering that coffee is very far from being the only popular beverage containing caffeine, it is not difficult to believe that caffeine […]

Sensory competition (1): A clash of odors

Neurobiology

By Jorge Mejías

For any animal, the real world is an ever-changing environment. Continuously, even then they are just remaining in a peaceful, awake state, animals receive multiple sensory signals encoding different features of their surroundings, or even carrying information about their own internal state (orientation, body movement, or internal temperature, for example). Some of these signals might […]

The functioning of the human brain goes far beyond a bunch of cells packed together; each of them is able to produce, receive, and transform electrical signals into a concrete response that affects the neighboring cells, counted by hundreds. This image is already complex, but if we say that the electric signals are constituted by […]

Neurobiology

By Jorge Mejías

Our brain constitutes one of the finest pieces of natural machinery known, and it allows us to efficiently interact with our environment: searching for food, avoiding predators, communicating with other individuals, and even some more sophisticated stuff — like enjoying a well composed piece of classical (or rock) music. However, all this comes at a […]

Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass electrodes are widely used, but they are fragile and they have high impedance. An intracellular […]
