<p style = "font-size:15px"> Electrophysiological recordings are highly non - stationary signals and therefore, difficult to model. We present a generative model that captures
the dynamics of these recordings with high – time resolution. Our representation allows for inferences beyond the scope of standard time-frequency based models.</p>

<img src="Picture3.jpg" alt="WM">
<p style = "text-align:justify; text-justify: inter-word; font-size: 15px"> Working memory is a complex cognitive process involved in encoding, storing and retrieving
sensory information. The process can be divided into 3 sub-phases: memory creation, maintenance and retrieval. Neurons in the prefrontal cortex (PFC) have been shown to maintain transiently elevated activity during delay period
in cued choice memory guided tasks. However, another school of thought supports, additionally, the involvement of population activity that
are exemplified in the complex dynamics underlying the field potentials. These dynamics correspond to oscillatory bursts (i.e., neuromodulations)
in the gamma and beta frequency bands. </p>
<p style = "text-align:justify; text-justify: inter-word; font-size: 15px"> Through this study, we aim to summarize the involvement of oscillatory dynamics
as the brain transitions between the different WM states during task execution. We sought to validate our hypothesis that neuromodulatory events
indicate the emergence of task variables, are representative of the stimulus, as well as encode correlates of executive control;
and therefore, they may be predictive of behavior. Simultaneously, we asked two critical questions: 1) what is the nature of encoding of neuromodulations?
and 2) how important is time - resolution for abstracting relevant information from field potentials? </p>

<p style = "font-size:15px"> Stage II of Non - Rapid Eye Movement (NREM) sleep is marked by stereotypical high frequency spike clusters known as sleep spindles, observable in the cortical electroencephalograms.
The identification of sleep spindles is usually carried out by visual inspection of signals obtained from polysomnography studies which both tedious and prone to errors.
In this study, we demonstrate the applicability of our model as a generalized sleep spindle detector. </p>
