Neural Circuits

1.7K
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...

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

  • To propose an interpretable deep learning model for COVID-19 detection using chest CT scans.
  • To enhance diagnostic accuracy and provide transparent reasoning for predictions.
  • To evaluate the model's performance against COVID-19, normal, and pneumonia patient data.

Main Methods:

  • Development of an interpretable deep learning model employing a positive reasoning process.
  • Training and validation of the model using a dataset of chest CT scans from COVID-19 positive, healthy individuals, and pneumonia patients.
  • Performance evaluation using metrics such as accuracy, precision, recall, and F-score.

Main Results:

  • The proposed interpretable deep learning model achieved high performance metrics.
  • Accuracy: 99.48%
  • Precision, Recall, and F-score: 0.99 for all.

Conclusions:
