Impact of depressed state on attention and language processing during news broadcasts: EEG analysis and machine learning approach

open access: yesScientific Reports, 2022
While information enriches daily life, it can also sometimes have a negative impact, depending on an individual’s mental state. We recorded electroencephalogram (EEG) signals from depressed and non-depressed individuals classified based on the Beck ...

The World as a Neural Network [PDF]

open access: yesEntropy, 2020
We discuss a possibility that the entire universe on its most fundamental level is a neural network. We identify two different types of dynamical degrees of freedom: “trainable” variables (e.g., bias vector or weight matrix) and “hidden” variables (e.g., state vector of neurons).

The pedunculopontine tegmental nucleus as a motor and cognitive interface between the cerebellum and basal ganglia

open access: yesFrontiers in Neuroanatomy, 2016
As an important component of ascending activating systems, brainstem cholinergic neurons in the pedunculopontine tegmental nucleus (PPTg) are involved in the regulation of motor control (locomotion, posture and gaze) and cognitive processes (attention ...

Contour detection by CORF operator [PDF]

open access: yes, 2012
We propose a contour operator, called CORF, inspired by the properties of simple cells in visual cortex. It combines, by a weighted geometric mean, the blurred responses of difference-of-Gaussian operators that model cells in the lateral geniculate ...

Neural network approximation [PDF]

open access: yesActa Numerica, 2021
Neural networks (NNs) are the method of choice for building learning algorithms. They are now being investigated for other numerical tasks such as solving high-dimensional partial differential equations. Their popularity stems from their empirical success on several challenging learning problems (computer chess/Go, autonomous navigation, face ...

Reward and behavioral factors contributing to the tonic activity of monkey pedunculopontine tegmental nucleus neurons during saccade tasks

open access: yesFrontiers in Systems Neuroscience, 2016
The pedunculopontine tegmental nucleus (PPTg) in the brainstem plays a role in controlling reinforcement learning and executing conditioned behavior. We previously examined activity of PPTg neurons in monkeys during a reward-conditioned, visually guided ...

A new neural network technique for the design of multilayered microwave shielded bandpass filters [PDF]

open access: yes, 2009
In this work, we propose a novel technique based on neural networks, for the design of microwave filters in shielded printed technology. The technique uses radial basis function neural networks to represent the non linear relations between the quality ...

Adaptive Learning Gabor Filter for Finger-Vein Recognition

open access: yesIEEE Access, 2019
Presently, finger-vein recognition is a new research direction in the field of biometric recognition. The Gabor filter has been extensively used for finger-vein recognition; however, its parameters are difficult to adjust.

Enhanced academic motivation in university students following a 2-week online gratitude journal intervention

open access: yesBMC Psychology, 2021
Background Past studies have associated gratitude interventions with a host of positive outcomes. However, there is a dearth of research regarding the impact such interventions have on the academic motivation of university students, thought to be a ...

How two brains make one synchronized mind in the inferior frontal corex: fNIRS-based hyperscanning during cooperative singing

open access: yesFrontiers in Psychology, 2015
One form of communication that is common in all cultures is people singing together. Singing together reflects an index of cognitive synchronization and cooperation of human brains.
