Scientists discover protective strategy against pesticide-linked Parkinson’s disease


Exposure to a group of common pesticides, called dithiocarbamates, has long been associated with an increased risk of Parkinson’s disease, although the mechanism by which the compounds exert their toxicity on the brain has not been completely understood. A new UCLA study sheds light on the toxicity of the compounds while also suggesting a strategy that may help protect against the disease. Leer Más

Exploring synapses with a gigantic advantage

How does memory occur? And what about movement, or thinking? One key element to understand all these brain functions are the synapses. A synapse is the contact point between two neurons, where a signal is transmitted one-way, from one neuron to another. Specifically, from the pre-synaptic part of one neuron, to the post-synaptic part of another neuron. This communication process involves many types of proteins, and allows us, for example, to memorize a friend’s name. Moreover, synapses do not just pass ‘messages’ from one neuron to another, but also keep the strength of transmitting such ‘messages’ for a short or a long period of time, thus playing a main role in memory formation.
