Neural Regulation

39.8K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Physiology of Emotion01:20

Physiology of Emotion

1.3K
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Labeling Emotion01:20

Labeling Emotion

231
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)01:15

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

494
Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

Neural Circuits01:25

Neural Circuits

1.5K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Area of Science:

  • Neuroscience
  • Machine Learning
  • Affective Computing

Background:

  • Electroencephalography (EEG) based emotion recognition is crucial for understanding user affective states.
  • Current methods often overlook the structural information between brain regions, hindering accurate high-level EEG feature representation.
  • This limitation can lead to performance degradation in emotion recognition systems.

Purpose of the Study:

  • To propose a novel Nuclear Norm regularized Deep Neural Network (NRDNN) framework for EEG-based emotion recognition.
  • To effectively capture and leverage the structural information among different brain regions in EEG decoding.
  • To improve the accuracy and robustness of machine perception of users' affective states.

Main Methods:

  • Utilizing deep neural networks to learn high-level feature representations for individual brain regions.
  • Implementing a region-attention layer to automatically learn the contribution weights of each brain region.
  • Employing nuclear norm regularization on a stacked feature matrix to capture structural information across brain regions.
  • Developing an efficient end-to-end framework for EEG signal processing.

Main Results:

  • The proposed NRDNN framework successfully learns high-level EEG representations while considering inter-regional structural information.
  • The region-attention mechanism effectively adjusts the contributions of different brain regions.
  • Experimental results on a public emotion EEG dataset demonstrate state-of-the-art performance.
  • The NRDNN framework shows significant improvements by leveraging structural information.

Conclusions:

  • The NRDNN framework offers an effective approach for EEG-based emotion recognition by integrating structural information.
  • The method enhances machine perception of affective states through improved EEG feature learning.
  • The findings highlight the importance of considering inter-regional brain dynamics for advanced emotion recognition systems.
