How do neurons communicate to solve a cognitive task?

In a study published recently in the journal  PNAS the temporal interaction between the electrical activity of neurons of five cortical areas  of two primates has been quantified: the sensory cortical (S1 and S2), premotor (MPC, DPC) and motor (M1) areas, while the specimens performed a somatosensory discrimination task in which they had to indicate with the movement of the hand which stimulus received had the highest intensity.

In the resting state, the brain is constantly exploring its functions

Using techniques that measure brain activity according to oxygen consumption (BOLD fMRI), Adrián Ponce Álvarez, CBC researcher and Gustavo Deco, ICREA research professor and director of the CBC, together with a team of researchers from the USA, Italy, the UK and Switzerland have shown that the synchrony of the global phase evolves into a characteristic ultra-slow time scale (<0.01 Hz), and that the temporal variations observed reflect the transient formation-dissolution of multiple communities of synchronized brain regions.

A new method identifies changes in brain connectivity in psychiatric disorders

An international team of scientists comprising Gustavo Deco, ICREA research professor and CBC director and Joana Cabral, researchers CBC, have combined in their study the real functional connectivity obtained by advanced tractography with anatomical brain parcellation to identify the connectivity or "fingerprint" of the target points of deep brain stimulation (upf.news).

The brains of bilinguals and monolinguals differ when they speak their mother tongue

Albert Costa, ICREA research professor and SPB director, together with Kristof Strijkers, former SPB researcher, have participated in a study which has shown that when performing language tasks, bilinguals and monolinguals use the areas of the brain involved differently, even though the language studied is the native and dominant one (upf.news).

Functional connectivity dynamics, a new biomarker of some mental diseases

In a study published this January by a team of scientists including Gustavo Deco, ICREA research professor and director of the CBC, have shown that functional connectivity dynamics (FCD) of the neural networks of the cerebral cortex, are a good biomarker of neural activity in a state of rest of the brain, so that the study of disorders of the FCD can guide the diagnosis, prognosis and individual treatment of some of the more prevalent mental diseases, such as Alzheimer's disease or schizophrenia (upf.n

New ways open to preserve the memory and cognitive functions with age

The effects of neurobiological changes in aging are presented in a study published in the journal Neurology of Learning and Memory, by Gustavo Deco, ICREA research professor and director of the CBC, together with Edmund T. Rolls, a member of the Centre for Computational Neuroscience at Oxford and of the Department of Computational Sciences at the University of Warwick in the United Kingdom (upf.news).
