A low-frequency oscillatory neural signal in humans encodes a developing decision variable
We often make decisions based on sensory evidence that is accumulated over a period of time. How the evidence for such decisions is represented in the brain and how such a neural representation is used to guide a subsequent action are questions of considerable interest to decision sciences. The neural correlates of developing perceptual decisions have been thoroughly investigated in the oculomo...
متن کاملCollateral as Signal Variable in a Business Partnership Contract: A Case Study of Refah Kargaran Bank
There is no convergence in the results of the credit relationship between the financial contracting parties (banks and customers) due to the different importance of the contract variables. Therefore, while examining the impact of the empirical relationship between the variables commercial profit-loss sharing contracts, the dual role of the collateral variable (screening and motivation) is in...
متن کاملUnsteady free convection oscillatory couette flow through a variable porous medium with concentration profile
In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...
متن کاملA Time-Frequency approach for EEG signal segmentation
The record of human brain neural activities, namely electroencephalogram (EEG), is generally known as a non-stationary and nonlinear signal. In many applications, it is useful to divide the EEGs into segments within which the signals can be considered stationary. Combination of empirical mode decomposition (EMD) and Hilbert transform, called Hilbert-Huang transform (HHT), is a new and powerful ...
متن کاملFrequency-dependent oscillatory neural profiles during imitation
Imitation is a complex process that includes higher-order cognitive and motor function. This process requires an observation-execution matching system that transforms an observed action into an identical movement. Although the low-gamma band is thought to reflect higher cognitive processes, no studies have focused on it. Here, we used magnetoencephalography (MEG) to examine the neural oscillato...
