Here, prefrontal cortex showed special features compared to primary areas, including increased firing rate and gamma oscillations, and firing patterns of single units.
Mesulam M Mesulam, M. Search Advanced search allows to you precisely focus your query. A pesar de ello, la actividad oscilatoria no se vio alterada, sugiriendo la existencia de mecanismos compensatorios.
Please enter User Name Password Error: The main technique used for this work is the recording of electrophysiological extracellular Local Field Potential signals, which mainly respond to the activity of local populations of neurons.
Single Unit recordings, which evaluate the firing properties of a single neuron, were also obtained in combination of LFP in some of the studies.

Secondly, here is presented the role of cortical excitability in the expression of those rhythms across different cortical areas. 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.
Otherwise it is hidden from view. 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.
This type of recordings was obtained both in brain slices and in vivo and was used in combination with other techniques. Although that, oscillatory activity, either in parameters of Slow waves or beta-gamma frequencies, remained unchanged, suggesting the existence of compensatory mechanisms.

Sign in via OpenAthens. First, this study presents de dependence of slow and fast rhythms on an intrinsic mechanism of neurons that governs cortical oscillations which is somtosensorial persistent sodium current.
In our study of prefrontal cortex, 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. 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. Principios de Medicina Interna, 18e. Este tipo de registros se ha obtenido tanto en rodajas de cerebro como in vivo. This work was performed in two cortical areas: In our study in somatosensory cortex, thalamocortical evoked potentials showed increased cortical inhibition.

Finally, we performed a study of the functional and anatomical alterations in the cortical network underlying cognitive deficits in a transgenic model of Down syndrome, TgDyrk1A mice.
