This type of recordings was obtained both in brain slices and in vivo and was used in combination with other techniques.

This work was performed in two cortical areas: Afasia, amnesia y otros trastornos cerebrales focales. View All Subscription Options.

Figura Caras externa arriba e interna abajo de los hemisferios cerebrales. This study also included a measurement of the speed of propagation of UP states, because prefrontal cortex was found to present a reduced Coefficient of Variation of UP state duration, compatible with being an area of wave generation.

Este tipo de registros se ha obtenido tanto en rodajas de cerebro como primariz vivo. From the work of this Thesis, we demonstrated some mechanistic aspects that control the emergence of rhythmic patterns from cortical circuits, with a striking role on the mechanisms which control excitability or cortical connectivity that underlies oscillations.

Please use this identifier to cite or link to this item: Here, we saw that blocking this current with phenytoin provoked the elongation of UP states and increased firing rate of the network, while the generation of new UP states was prevented.

In another study, we performed a comparison of the oscillatory activity along different cortical areas in vivo.

In our study in somatosensory cortex, thalamocortical evoked potentials showed increased cortical inhibition. Please enter User Name.

Here, prefrontal cortex showed special features compared to primary areas, including increased firing rate soomatosensorial gamma oscillations, and firing patterns of single units.

This unbalance between excitation and inhibition was later demonstrated at anatomical level, and may explain our findings of altered behavior in cognitive tasks that involved prefrontal cortex such as the puzzle box. A pesar de ello, la actividad oscilatoria no se vio alterada, sugiriendo la existencia de mecanismos compensatorios.

Single Unit recordings, primmaria evaluate the firing properties of a single neuron, were also obtained in combination of LFP in some of the studies. Please enter Password Forgot Username?

In the first study, we aimed to disclose the role of persistent sodium current in controlling cortical oscillatory activity, either in the generation and maintenance of UP states in slow oscillations and the control of fast beta-gamma oscillations.

Thus, we aimed to demonstrate a main pattern of propagation of slow waves from frontal areas to posterior areas, as previously described in humans.

These findings can all be understood within frame of altered balance between excitation and inhibition. Otherwise it is hidden from view. In our study of prefrontal priamria, TgDyrk1A mice presented alterations in oscillatory activity that were compatible with as more inhibited network, such as decreased firing rate, decreased gamma oscillations and a slower speed of propagation.
