Semantics, categories and the brain.

How the brain stores and manipulates categories of objects is a quite interesting scientific question – but a difficult one. Every noun in a language represents some sort of category. Oak trees, for instance, is a category that regroups every individual oak tree. Continue reading

The science behind Obama’s BRAIN project.

On April 2nd, 2013 President Obama announced the BRAIN initiative, a project aimed at understanding brain activities at a level of detail that is unprecedented. A lot has been said and written about the initiative but some people feel in the dark as to what are its precise aims. Continue reading

Microglia

New study identifies a role for microglia in the development of cortical neurons.

A recent study to be published in Nature Neuroscience has identified the role of a type of brain cells called microglia in the development of specific types of cortical neurons1. As you can see in the first image below, the cerebral cortex – the outer layer of the brain – comprises six separate layers. These layers can be identified under the microscope. Continue reading

Neuroscientists map the activity of sensorimotor cortex for speech articulation.

A new study published in Nature reveals some of the dynamics of neural activity when people articulate syllables commonly used in English1. The researchers have taken advantage of a therapy that patients were about to follow for epilepsy. In some cases of epilepsy, doctors need to locate the region of the brain that induces seizures. To do so they place a series of electrodes right on the surface of the brain, under the cranium. The technique is called Electrocorticography. Since the patients were to wear that device for some time, they were asked if they would be willing to make some articulation exercises while the electrical activity on the surface of their brain was recorded through this device. Continue reading
