Classification of Neurotransmitters

Classification of Neurotransmitters

Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Neural Regulation

Neural Regulation

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.

Purpose of the Study:

To develop a novel deep learning framework for joint analysis of neuroimaging and genetic data.
To improve the accuracy of disease classification and feature selection in complex brain diseases.
To enhance the interpretability of deep learning models in medical research.

Main Methods:

Construction of brain region-gene networks to represent pathogenetic factor associations.
Development of a feature information aggregation model for brain region and gene nodes.
Proposal of a feature information aggregation and diffusion generative adversarial network (FIAD-GAN) incorporating novel convolution and deconvolution operations.

Main Results:

FIAD-GAN achieved superior performance in various disease classification tasks.
The model successfully extracted brain regions and genes strongly associated with Alzheimer's disease (AD).
Improved interpretability of the deep learning framework was demonstrated.

Conclusions:

FIAD-GAN offers a novel and efficient method for joint analysis of neuroimaging and genetic data.
