We study two-dimensional cellular automata, each cell takes three states: resting, excited and refractory. A resting cell excites if number of excited neighbours lies in a certain interval (excitation interval). An excited cell become refractory independently on states of its neighbours. A refractory cell returns to a resting state only if the number of excited neighbours belong to recovery int...

Complex neural modules with embedded neural development and synaptic plasticity features have been connected to form a hierarchical recurrent circuit. Virtual electrodes have been used to record a “neural” generated signal, called electrochipogram EChG, from each module. The EChG are processed by frequency domain methods to determine the modifications in functional connectivity by assessing qua...

We combined measures of resting-state functional magnetic resonance imaging and diffusion tensor imaging (DTI) to investigate alterations of function-structure relationships in patients with early-onset schizophrenia. DTI analysis revealed reduced fractional anisotropy in right frontal white matter. Corresponding gray matter regions showed reduced functional connectivity with other regions in t...

Recent studies of the structural and functional development of the human brain over the early years have highlighted the rapid development of brain structures and their interconnectivity. Some regional functional specializations emerge within the first months after birth, while others have a more protracted course of development spanning over the first decade or longer. While some anatomical ch...

Physical activity leads to a respiratory behaviour that is very different to a resting state and that influences speech production. How speech parameters are exactly affected by physical activity remains largely unknown. Hence, we investigated how several prosodic parameters change under influence of physical activity and focused on temporal and breathing characteristics which have not been add...

The transition from adolescence to adulthood is a critical stage in the human lifespan during which the brain still undergoes substantial structural and functional change. The changing frequency composition of the resting state EEG reflects maturation of brain function. This study investigated (post)adolescent brain maturation captured by two independently but simultaneously recorded neuronal s...

rent and slow sustained (L-type) current, the alteration in the high-NaCI group was attributable to the change in L-type current. The steady-state inactivation curve was not different between the high-NaCI and low-NaCI groups. In conclusion, L-type Ca2+ channels in resistance arteries of Dahl salt-sensitive rats became more available for opening near the resting potential after dietary salt-loa...
