“…In future, such dynamics should be discussed in the networks containing many neurons. Synchronization states and synchronization transitions have been experimentally shown to play very important roles in information processing in neuroscience and in the generation of complex rhythms in coupled cardiac myocytes [3,4,[7][8][9]19,20]. The relationships between the simulation and experimental results should be established in future studies.…”

“…Transitions between various synchronization states have been observed in experiments on cardiac myocytes, on oddball tasks, and in the cardiorespiratory system [3,[7][8][9]. Simulations of synchronization have had various results, such as spiking and bursting synchronizations and synchronization transition process [10][11][12][13][14][15][16][17][18].…”

As the value of a control parameter decreases, monostable bursting changes to monostable spiking via the coexistence of spiking and bursting in a Leech neuron model, and the attraction domain of the bursting decreases, while that of the coexisting spiking increases for coexisting behaviors. As the coupling strength increases, the two coupled Leech neurons with the coexisting spiking and bursting manifest transitions from non-synchronization to complete synchronization (CS) through a complex process, which is dependent of the values of the control parameter, cases of configurations (one neuron spiking and the other bursting, both bursting, and both spiking), and the initial values of the two neurons. The transition processes involve various spiking and bursting or chaos synchronization states for the first two cases given here, but contain only spiking patterns for the last case. Corresponding with the attraction domain, the probability of initial values that can lead to bursting patterns of CS decreases, but the probability of initial values that can induce spiking of CS increases for the former two cases, as the control parameter is decreased. This phenomenon can also be interpreted by the structure and volume of the attraction domain with which all initial values can only induce CS of spiking for case 3. The results may improve understanding of the synchronization dynamics of the coupled neurons with coexisting behaviors.

“…Synchronization states and synchronization transitions have been reported in the literature [55,56], which play very important roles in neuroscience [6][7][8][9][10]57]. In a recent paper, the synchronization transition processes of two coupled neurons have been simulated with co-existing spiking and bursting patterns lying between bursting and spiking.…”

“…For example, synchronization was detected experimentally in many nervous systems such as the mammalian visual cortex [6], human thalamocortical area [7] and stomatogastric ganglion of the spiny lobster [8]. Moreover, transitions between different synchronization states were discovered in visual sense and auditory sense in terms of difficulty degree in the oddball task [9,10] and evidenced in the human cardiorespiratory system [11]. These synchronization behaviors or synchronization transitions, experimentally observed in different functions, have been tightly related to the information transmission or processing in visual sense, learning, cognition, movement control and perception [6,[10][11][12][13].…”

“…Furthermore, effects of task set have been found in target detection experiments, where the task set implies the storage of a specific target template and subsequent matching of stimuli with this template. Several studies have found that GBA evoked by targets (simple geometric shapes) is larger than GBA evoked by standards (Busch et al, 2006b;Herrmann and Mecklinger, 2000;Kim et al, 2008). According to Engel et al (2001), attention that is directed towards specific features can synchronize subthreshold oscillations of feature-selective assemblies prior to stimulus presentation.…”

Cortical oscillatory activity in the gamma-band range (>30Hz) is a fundamental mechanism of neural coding that arises during a range of cognitive processes in both animals and humans. Since the first report on high frequency oscillatory synchrony between V1 neurons belonging to the same orientation column (Gray and Singer, 1989, PNAS, 86, 1698-1702), the role of such oscillations in visual perception has been extensively researched. Visual stimuli elicit an early, evoked gamma-band response and a later, induced (neither time nor phase-locked) response. An abundance of experimental evidence now links both evoked and induced high frequency oscillations to a range of visual stimulus properties. On the basis of early studies into gamma-band oscillations in vision, induced high frequency oscillatory activity has been proposed as a putative cortical mechanism of coherent percept formation and object representation while evoked high frequency activity was related to the processing of image features. Recent studies demonstrate that both evoked and induced gamma-band activity are correlated with the speed and accuracy of visual detection and discrimination. Furthermore, induced gamma-band oscillations in the visual cortex are also correlated with fixational eye movement patterns. These direct relations between gamma-band activity and the efficacy of visual perception strongly suggest that cortical high frequency synchronisations constitute a neural mechanism that subserves processes essential for the organised intake and analysis of visual information.
