With only 100,000 neurons, the fruit fly Drosophila Melanogaster confirms that sleep is not only good for skin and mood, but also for memory. American researchers at Florida Campus of The Scripps Research Institute published in the journal Cell that remembering and forgetting are two processes closely related, dependent on the activation or inactivation of […]

A mouse model for type B tyrosine hydroxilase deficiency
Tyrosine Hydroxylase Deficiency (THD) is an inborn error of dopamine synthesis. Around 70 cases of THD have been identified so far, with manifestations ranging from mild movement disorder to encephalopathy with parkinsonism. Based on the clinical signs observed, two main forms have been described. Type A has a more attenuated phenotype and it is normally […]
Mitochondrial disorders: impaired neurotransmission and seizures
Seizure are frequent symptoms of inborn errors of metabolism. In particular, 26–60% of all mitochondrial disorders occur with epilepsy, and 169 genetic mutations affected mitochondrial function have been associated to seizures. Dr. Zsurka and Dr. S Kunz from Bonn University, Germany, proposed an accurate review, recently published in the journal Lancet Neurology, of the relationship […]
Can creativity be trained? Music and the brain
Creativity is defined by novelty and meaningfullness and the creative production involves the generation of new possibilities as well as the selection and combination of previously produced ones. Several areas in the brain have been related with creativity: dorsolateral prefrontal cortex, the anterior cingulate cortex, the presupplementary motor area, and the inferior frontal gyrus (see […]
A computer system that can simulate the brain
Scientists from Stanford University have generated a model capable of simulating brain activity (Benjamin BV et al). It’s capable of simulating a million neurons with billions of synaptic connections. The amount of power required is similar to that necessary for running a tablet computer. They’re calling the system Neurogrid. It’s composed of 16 Neurocore chips that […]
