The Contextual Effect On Value Learning Procedure

IPM SCS Webinar

Abstract:


Numerous surveys and surveys over the past two decades show that 60 to 80% of companies do not achieve their strategic goals. When we talk about strategic management, we consider the three stages of strategy development, implementation, and evaluation as the main stages, and we consider strategic management as a technical process, step by step and stages that from the development of orientation pillars begins with environmental analysis and surveys and the development of strategies continues and ends with specific operational measures. In recent years, many strategic plans have been developed with the same approach in organizations, but as stated and research shows that many of these plans in practice and especially in achieving goals and influencing Key performance variables of the organization have failed. The success of organizations in dynamic and uncertain market conditions requires managers who have special capabilities to create value creation methods and modify previous ways and methods and have a deep understanding of the complexity of cause-and-effect relationships between market variables and components. Branches and disciplines such as behavioral strategy and cognitive psychology refer to these competencies as managers 'cognitive competence and strategic management thinkers consider managers' cognitive competence as the basis of the organization's dynamic capabilities. Having a behavioral view of strategy paves the way for improving the effectiveness of strategies in the field of operations. We have to accept that the strategic management process is not just a technical process, and the cognitive abilities of managers in this area can play an effective role in promoting the effectiveness of strategic plans. This webinar seeks to provide a model and framework to explain the role of managers' cognitive abilities in implementing strategies.

Abstract:


Modern multi-channel recording devices offer the opportunity to untangle the coordination mechanisms of neural activity at a mesoscopic level. However, this requires novel multivariate analysis techniques that link the high-dimensional data with biophysically realistic models of network activity. We develop a methodology to generalize the analysis of spike-field coupling (SFC) to the multi-channel setting, while allowing interpretability of such coupling based on neural field models of network activity. SFC characterizes the relation between the spiking activity of individual neurons and field activity, reflecting mesoscopic network dynamics, and typically measured by Local Field Potentials (LFP). Although SFC approaches have been extensively applied, they were focused on quantifying coupling one pair at a time (between one unit and one LFP channel), thereby remaining largely blind to the population-level interactions that generate them. As a consequence, the rich spatiotemporal patterns of spikes and LFPs remained largely under-exploited, despite the insights into the underlying circuit dynamics they may provide.



We introduce "Generalized Phase Locking Analysis (GPLA)" that summarizes the spike-field coupling from multi-channel data by three interpretable quantities: LFP and spike vectors represent the dominant spatial distribution and relative phase shifts of neuronal ensemble and field activity in the recorded structure, while the generalized Phase Locking Value quantifies the strength of the coupling between these patterns.



Furthermore, we demonstrate the capability and interpretability of GPLA with various simulated and experimental datasets. First, GPLA’s performance is superior to univariate measures in the presence of large amounts of noise. Next, the application of GPLA on simulations of hippocampal sharp-wave-ripples (SWR) reveals various characteristics of hippocampal circuitry (e.g. communication flow from CA3 to CA1 during the SWR) with minimal prior knowledge. Finally, combining neural field simulations and GPLA applied on Utah array data recorded from anesthetized macaque reveals synchronized clusters of sites/neurons. This global pattern of synchronization PFC supports long-range excitatory horizontal connections and strong local recurrent inhibition as a plausible connectivity scheme of the recorded structure (ventrolateral Prefrontal Cortex), that has been partially verified experimentally.



Lastly, we address one of the challenges of statistical analysis of parallel spike trains by taking a step beyond bootstrapping methods. We exploit novel statistical frameworks, namely the random matrix theory, and provide an analytical significance test. This is of paramount importance given the increasing dimensionality of modern recording techniques, such as Neuropixel, that need computationally efficient statistical tests.



In summary, with GPLA, we can quantify, characterize, and statistically assess the interactions between population spiking activity and mesoscopic network dynamics.

Abstract:


In the natural environment, organisms are constantly exposed to a continuous stream of sensory input. The dynamics of sensory input changes with organisms behaviour and environmental context. The contextual variations may induce textgreater 100 fold change in the parameters of the stimulation an animal experiences. Thus, it is vital for the organism to adapt to the new diet of stimulation. The response properties of neurons, in turn, dynamically adjust to the prevailing properties of sensory stimulation, a process known as ‘neuronal adaptation’. Neuronal adaptation is an ubiquitous phenomenon across all sensory modalities and occurs at different stages of processing from periphery to cortex. Here, I will discuss the recent finding about the neuronal adaptation in the rodent whisker-mediated touch system and further summarise the functional effect of neuronal adaptation on the response dynamics and encoding efficiency of neurons at single cell and population level along the whisker-mediated touch system in rodents.
