“…Selective attention, behavioral training, and electrical kindling can simultaneously increase synchronization and decrease receptive Weld size (Fries et al, 2001;Luck et al, 1997;Gassanov et al, 1985;Steinmetz et al, 2000;Vaadia et al, 1995;Schoenbaum et al, 2000;Sakurai, 1993;Schieber, 2002;Salazar et al, 2004;Valentine et al, 2004). Pairing NB stimulation with noise burst trains causes receptive Welds to increase but decreases the amount of synchrony between A1 recording sites (Bao et al, 2003).…”

Experience dependent plasticity alters cortical synchronization

Theories of temporal coding by cortical neurons are supported by observations that individual neurons can respond to sensory stimulation with millisecond precision and that activity in large populations is often highly correlated. Synchronization is highest between neurons with overlapping receptive fields and modulated by both sensory stimulation and behavioral state. It is not yet clear whether cortical synchronization is an epiphenomenon or a critical component of efficient information transmission. Experimental manipulations that generate receptive field plasticity can be used to test the relationship between synchronization and receptive fields. Here we demonstrate that increasing receptive field size in primary auditory cortex by repeatedly pairing a train of tones with nucleus basalis (NB) stimulation increases synchronization, and decreasing receptive field size by pairing different tone frequencies with NB stimulation decreases synchronization. These observations seem to support the conclusion that neural synchronization is simply an artifact caused by common inputs. However, pairing tone trains of different carrier frequencies with NB stimulation increases receptive field size without increasing synchronization, and environmental enrichment increases synchronization without increasing receptive field size. The observation that receptive fields and synchronization can be manipulated independently suggests that common inputs are only one of many factors shaping the strength and temporal precision of cortical synchronization and supports the hypothesis that precise neural synchronization contributes to sensory information processing.

“…Cytological and antidromic stimulation studies suggest that there should be direct interaction between distant neurones with delays of many tens of milliseconds, but these have been reported only occasionally in cross-correlation studies (e.g. Gassanov et al 1985). More powerful statistical methods, such as Abeles' triple correlation technique (Abeles 1982a, b), or methods for identifying favoured spike trains (Frostig et al 1990), are usually needed before these long-delay interactions can be revealed.…”

Much evidence suggests that the mammalian thalamus is not merely a set of nuclei relaying signals to the cerebral cortex, but is engaged in two-way interplay with it. Three important features constrain ideas about the nature of this interplay: (i) thalamic projection neurones lack local axon collaterals; (ii) most corticothalamic projections have very long axonal conduction time; (iii) in the waking state the membrane potential of thalamic projections cells appears to be poised just beneath threshold for firing. It is proposed that corticothalamo-cortical pathways represent connections between different cortical loci which have higher security than the direct cortico-cortical route. Thus each thalamo-cortical projection neurone can have a singular and pivotal role in the activation of one or more cortical neural assemblies. The long delays of cortico-thalamic conduction suggest that the cortico-thalamo-cortical loop also plays a crucial role in the operation of time-structured neural assemblies ('synfire chains'; Abeles), by providing a high-security link from one active node of the chain to nodes activated at a later time in the sequence. It is predicted that, in the waking animal, thalamic projection cells should have a response selectivity to complex percepts and concepts, conferred on them by the cortical assemblies in whose activation they participate.

“…The cooperative activity between single neurons can provide information about the computations and network properties of neuronal populations during the performance of cognitive tasks. Now the cooperative activity of motor, auditory, visual cortex, hippocampus, lateral hypothalamus, basolateral amygdala was made during different goal-directed behaviors at monkeys [6]- [9], cats [10]- [12] and rats [13], but without the paradigm "law of choice".…”

Cats placed in the situation of a choosing between a high-value time-delayed and a low-value immediate food rewards elected to wait for the preferred reward or to obtain the worse reward quickly. On the basis of the selected behavior strategy the cats were classified into three groupsself-control ones, choosing predominantly a delayed high-value food reward, impulsive, choosing predominantly an immediate low-value food reward, and ambivalent-with mixed types of reactions. The correlated firing between simultaneously recorded neurons in prefrontal cortex (PFC), n. accumbens (NAcb) and dorsomedial striatum (DMStr) during choice behavior task was studied. It was revealed that a total number of NAcb functional neuron interactions at cats show self-control reactions exceeded that observed at ambivalent and impulsive cats. The number of PFC and DMStr functional correlated firing at impulsive and ambivalent cats was more significant than that at cats capable to self-control. Observed correlated firing between PFC and NAcb neurons (fronto-accumbal interactions) progressively increased with the shift of behavior to impulsiveness and decreased with self-control behavior. Our results demonstrate that performance of impulsive and self-control behavior alters the correlation structure of neural firing in PFC, NAcb, DMStr and suggest the key role of local PFC, NAcb, DMStr networks in realization of choice behavior.
