	abstract = {A neural network is a machine learning algorithm that can learn and make predictions by adjusting the strength of the connections between nodes. The sigmoid function is commonly used as an activation function in these nodes. This study explores the potential applicability of biological materials in the development of alternative activation functions. Inspired by the fact that acetylcholine induces intestinal contractions that follow a sigmoid function, we used pharmacological data obtained from guinea pig ilea in a layered neural network for image classification tasks. We found that the intestinal data-based neural network with the same structure as a conventional three-layer perceptron achieved an impressive classification accuracy of 85.7\% {\textpm} 0.6\% based on the MNIST handwritten digit dataset (chance = 10\%). Additionally, the neural network was trained to determine whether objects in photographs collected from the internet were digestible, achieving an accuracy of 88.5\% {\textpm} 0.9\% (chance = 50\%). Our approach highlights the potential applicability of intestine data in neural computations based on pharmacological mechanisms.Competing Interest StatementThe authors have declared no competing interest.},
