Restauración de la conectividad talamocortical después de la recuperación del estado vegetativo persistente
Lancet (London, England)
|June 1, 2000
Resumen
La conectividad cerebral funcional entre los núcleos tálamicos y la corteza prefrontal se altera en un estado vegetativo. Esta conectividad se recupera después de que se restaura la conciencia, lo que indica su importancia para la conciencia.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- La neuroimagen es una técnica de neuroimagen.
- Neurología Clínica Neurología Clínica
Sus antecedentes:
- El estado vegetativo (VS) se caracteriza por una pérdida de conciencia a pesar de las funciones autónomas conservadas.
- Comprender los correlatos neuronales de la conciencia es crucial para diagnosticar y manejar los trastornos de la conciencia.

Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Neurogenesis and Regeneration of Nervous Tissue
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
