What do you know about interneurons? Which processes do you think they regulate? How could dysfunction in interneurons and abnormal gabaergic transmission contribute to the pathophysiology of some neuropaediatric disorders? Interneurons were classically described as short-axon neurons with connections between “input” and “output” principal cells and were recognized for their role in modulating excitability via […]

Neurotransmisión colinérgica y cerebro en desarrollo
What do you know about acetylcholine? What about its role in the developing brain? Are there diseases of the central nervous system due to abnormal cholinergic transmission in paediatrics? Our current knowledge about disorders of neurotransmission in children is focused on transmitters such as dopamine, serotonin or GABA. By contrast little is known about the […]
Serotonina y arquitectura del córtex cerebral
The neurotransmitters sculpt the brain Serotonin is an abundant neurotransmitter in the brain. During development, serotonin regulates processes such as neuronal migration and dendrite differentiation through some particular 5HT receptors. Abnormal serotoninergic neurotransmission during early periods of life may disrupt the construction of cortical circuits and contribute to neurologic and neuropsychiatric disorders. The human […]
Nuevas perspectivas en el Conectoma Humano
La fMRI en resposo proporciona información muy valuosa de las conexiones neuronales a nivel celular individual 25 de junio 2013; por Elisenda Cortès-Saladelafont Durante la última década ha habido un incremento importante de publicaciones sobre que ponen de manifiesto el interés creciente en el conexoma humano, no sólo a nivel anatómico, si no también a nivel […]
Synaptic brain
En la pantalla Retina del iPad todo se ve a las mil maravillas. Los textos son supernítidos, los colores brillan con luz propia y las fotos y vídeos tienen una definición asombrosa. Todo gracias a sus 3,1 millones de píxeles, un millón más que en un televisor HD.
